SOURCE: clutch

the acuating cylinder for the clutch needs to be replaced. this explains why you ahve no resistance when you deprress the clutch peddle. when adjusted right you should have no more than 1-1 1/2 inches of free play in the clutch peddle. and since the car will be in gear with out the clutch being pressed tells me that the clutch itself is good. please rate this

SOURCE: cant shift? reverse grinds? and pressure in clutch is low

What you describe sounds very much like the clutch is failing to disengage.
Fluid level being fine and no leaks under the car is good, but doesnt mean there isnt something wrong with either the master cylinder, slave cylinder, or the associated parts.

Highly unlikely there is a fault with the flywheel or clutch as failures with these would normally give no drive in any gear.

SOURCE: turbo 350 trans no forward gears but does have reverse

It's either your servo, or your bands.
Either way, the tranny needs a good cheap shop repair.
I'd just get a warrantied salvage yard tranny if I were you and save a few hundred bucks.

Why would a vehicle in reverse move forward


The question is a little vague but I think I know what your referring to. All modern automatic transmissions have torque converters. This is the device that connects the engine to the transmission. All vehicle manufacturers like the trans to be nice and smooth shifting. That's great but it does come with some minor drawbacks. If you are facing slightly down hill and you put your car in reverse but do not step on the gas slightly I can guarantee that you will indeed roll forward. You can eliminate that issue by holding your left foot on the brake while you shift into reverse. Then, as soon as you feel the trans engage, gently depress the gas pedal with your right foot and it will eliminate that forward roll problem.

Shudder in reverse and seems to be slipping forward gears good


It is an auto I take it and the problem will be a reverse band/clutch pack solenoid servo. It it is a manual then the clutch works the same way in forward and reverse so if it was slipping in reverse ,it would also be slipping in forward gears as well. Run the fault codes to check for TCM and servo/solenoid faults.

Toyota sienna 2001 won't go in reverse but it goes forward


Does it crunch? If you lift the clutch and then press it down whilst trying to get it into reverse as this lets the cogs move allowing you to slip the drive into the gears this may allow you to get it into reverse. So here's the steps:
1 start the the engine
2 drive the car for about 10 kms
3 try and get the vehicle into reverse
4 lift the clutch whilst holding the stick in the gate ( you should feel the cogs turning and shaking the stick)
5 then push the clutch down again
6 if it still won't go repeat step 4/5
if it still won't work then try and get it into reverse whilst stationary and then start the engine it will jolt but can free up the gears!

hope this helps :)

I have 2005 Chevy Suburban; when you engage the gear in drive the truck would move but won't get out of the first gear. I've checked my transmission fluid and its ok. It also responds to reverse when you...


Common problem probably a 4L60E transmission The low and reverse clutches are the same ones The forward clutches are another set and then there are the 3-4 clutches in another pack. So you probably burn out the forward clutches or could be a stuck valve in the valve body. Time for a transmission specialist.

My son has a '91 Pulsar, 5 door hatch. When he changes into reverse, the gear "grates", we beleive the clutch needs to be adjusted, is this correct? (he has no bother with any other gear...


When the engine is idling and the gear box selector is in Neutral all the internals of the gearbox are rotating. Pushing in the Clutch disconnects the drive from the engine to the gearbox but it takes a few seconds for the gears in the box to cease rotating. All the forward gears have synchromesh so there will be no crunching noise ifa forward gear is selected immediately the clutch is pushed in before allowing the gears to stop spinning. On the other hand Reverse has No synchros and therefore selecting reverse before waiting a few seconds for the gears to stop spinning will produce the crunching noise you have described.
So it pays to wait a second or two after pushing in clutch before Reverse is selected to minimise the crunch and if the clutch appears to be working correctly in normal driving ,then no adjustment is necessary.

Clutch


It does sound like a clutch, but deserves to be more thouroughly checked out, Does the clutch pedal feel normal? is there a little free-travel at the top of the pedal stroke? do you see oil dripping under the car?
Clutches usually go out slowly, they start to slip under heavey load first, then gradually slip even under light loads in low gears. If an axle was loose, it could have spun in it's hub, with the hood open ans an observerstanding beside the car looking down at the axles, slowly let the clutch out (engine running, in reverse gear, ) being careful not to hit your assistant, if the axles turn- one of them, but the wheel doesn't this is your problem. If the axles don't turn with the clutch out, and engine still revs, well it's time for a clutch or transmission, Good luck, hoe this helps

4R100 or 4R70W?

Geartrain
Power is transmitted from the torque converter to the geartrain components through the input shaft and forward clutch cylinder.
  • By holding or driving certain members of the gearset, four forward ratios and one reverse ratio are obtained and transmitted to the output shaft. The ratios are as follows:


GEAR RATIO 1ST 2.71 to 1 2ND 1.54 to 1 3RD 1.00 to 1 4TH 0.71 to 1 REVERSE 2.18 to 1
Input Shaft
The input shaft is supported by two bushings in the stator support. End positioning of the input shaft is controlled by the splines in the converter turbine and the overdrive planet assembly.
Output Shaft
The output shaft is supported by two bushings in the case and by the slip-yoke and bushing in the extension housing. End positioning is controlled by the parking pawl gear and snap ring or shoulder and by the reverse ring gear hub and snap ring.
Overdrive System
The overdrive planetary system consists of the overdrive planet assembly, overdrive sun gear, overdrive ring gear, coast clutch cylinder, overdrive one-way clutch assembly and the center shaft, as shown in the following illustration. The overdrive planet assembly is splined to the input shaft. The overdrive sun gear is centered by a bushing on the input shaft and held in place laterally by needle bearings on the reactor support and the overdrive planet assembly. The overdrive sun gear is splined to the coast clutch cylinder, which in turn is splined to the overdrive one-way clutch inner race.
The outer race of the one-way clutch is splined to the overdrive ring gear, which is splined to the center shaft. The center shaft is centered by the forward planetary assembly and is laterally held by needle bearings on the center support and the overdrive planet assembly. The center shaft is splined into the forward clutch cylinder.
Two friction clutches are assembled in the overdrive planet assembly. The coast clutch is splined between the coast clutch cylinder and the overdrive ring gear. The coast clutch is activated to perform engine braking in MANUAL 1, MANUAL 2 and third gear with the transmission control switch engaged.
The overdrive clutch is splined between the case and the coast clutch cylinder. The overdrive clutch holds the coast clutch cylinder and, in turn, the overdrive sun gear, to permit the planet assembly to overdrive the ring gear.
--------------------------------------------------------------------------------------------
Forward Drive System
The forward drive system consists of the forward clutch cylinder, intermediate brake drum, intermediate one-way clutch, input shell, forward ring gear, forward ring gear hub, forward/reverse sun gear and the forward planetary carrier and forward planetary gears.
The forward clutch cylinder is splined on the center shaft. The forward ring gear is piloted on the forward ring gear hub. Thrust bearings on the forward planet assembly and forward clutch cylinder hold the forward ring gear hub in place.
The intermediate brake drum is radially supported by bushings on the center support and is laterally controlled by thrust washers on the forward clutch cylinder and center support. The intermediate brake drum has the inner race of the intermediate one-way clutch press-fitted on its pilot. The intermediate one-way clutch's outer race is splined to the intermediate friction clutch, which is splined to the case. The intermediate brake drum has lugs that are slotted into the input shell to form a mechanical connection. The input shell is splined into the forward/reverse sun gear. The forward/reverse sun gear is common to two planetary gearsets. The forward planet is splined to the output shaft and is laterally positioned by needle bearings on the sun gear and on the forward clutch cylinder, as shown in the following illustration.
Two friction clutch assemblies, the direct clutch and the forward clutch, are shown with the forward planetary assembly. The direct clutch assembly splines the forward clutch cylinder to the intermediate brake drum. The forward clutch assembly splines the forward clutch cylinder to the forward ring gear. The forward clutch is activated during all forward gears. While in third or fourth gear, both the direct and forward clutches are applied to hold the forward planetary assembly and enable it to act as a solid shaft.
In second gear, the intermediate clutch assembly holds the forward/reverse sun gears. It is applied, along with the intermediate one-way clutch, to hold the intermediate brake drum, input shell and forward/reverse sun gear. In higher gears, the one-way clutch overruns.
----------------------------------
Low and Reverse Drive System
The reverse planetary assembly consists of the reverse planetary carrier, reverse planet gears, the reverse ring gear, the reverse ring gear hub, the reverse clutch hub and the low-reverse one-way clutch assembly.
The reverse ring gear hub is splined to the output shaft and to the reverse ring gear. The reverse ring gear hub is laterally held by a needle bearing on the inner race of the low-reverse one-way clutch and a snap ring on the output shaft. The reverse planet assembly is splined to the low-reverse clutch hub. The low-reverse clutch hub is connected by the reverse clutch to the case. The inner race of the one-way clutch is bolted to the case.
The reverse clutch assembly is activated in REVERSE gear and in MANUAL 1. The reverse clutch bypasses the reverse one-way clutch during coast and MANUAL 1. The reverse clutch holds the reverse planet assembly in REVERSE gear to enable the sun gear to drive the reverse ring gear in the opposite direction.
-------------
Apply Components
The following information describes the operation of the three 4R100 one-way clutches.
One-Way Clutch—Overdrive
The overdrive one-way clutch, shown in the following illustration, transmits engine torque from the overdrive sun gear to the overdrive ring gear in first, second and third gear range. The overdrive one-way clutch transmits power when the sprags are engaged between the inner and outer races. The inner race is splined to the coast clutch cylinder, which in turn is splined to the overdrive sun gear. The outer race is splined to the overdrive ring gear.
The overdrive one-way clutch engages whenever the overdrive planetary system attempts to drive the overdrive sun gear clockwise when the overdrive ring gear has a counterclockwise torque from the vehicle. When torqued counterclockwise, the overdrive one-way clutch engages and acts as a wedge to lock the sun gear and the ring gear together. During coast, the overdrive one-way clutch enables the ring gear to overrun or spin at a faster rate than the sun gear.
The overdrive one-way clutch overruns when in overdrive (fourth gear). In overdrive, the coast clutch cylinder is held by the overdrive one-way clutch, which in turn holds the overdrive sun gear. This causes the overdrive planet assembly to walk around the sun gear and overdrive the overdrive ring gear. The inner race of the overdrive one-way clutch is thus held stationary while the outer race is allowed to overrun clockwise.

Shift Patterns Upshifts
Transmission upshifting is controlled by the powertrain control module. The PCM receives inputs from various engine or vehicle sensors and driver demands to control shift scheduling, shift feel and torque converter clutch (TCC) operation.
The PCM has an adaptive learn strategy to electronically control the transmission which will automatically adjust the shift feel. When the battery has been disconnected, or a new battery installed certain transmission operating parameters may be lost. The Powertrain Control Module (PCM) must re-learn these parameters. During this learning process you may experience slightly firm shifts, delayed, or early shifts. This operation is considered normal and will not affect the function of the transmission. Normal operation will return once these parameters are stored by the PCM.
---------------------------------------------------------------------
Apply Components Band — Overdrive
For component location, refer to Disassembled Views in this section.
During 2nd and 5th gear operation, hydraulic pressure is applied to the overdrive servo.
  • This pressure causes the piston to move and apply force to the band.
  • This action causes the overdrive band to hold the overdrive drum.
  • This causes the overdrive sun gear to be held stationary through the adapter plate and the overdrive drum.
Band — Low/Reverse
For component location, refer to Disassembled Views in this section.
During 2nd gear operation, 1st gear operation and reverse, hydraulic pressure is applied to the low/reverse servo.
  • This pressure causes the servo to move and apply force to the low/reverse band.
  • This action causes the low/reverse brake drum to be held.
  • This action causes the low/reverse planetary assembly to be held stationary.
Band — Intermediate
For component location, refer to Disassembled Views in this section.
During 3rd gear operation, hydraulic pressure is applied to the intermediate servo.
  • This pressure causes the servo to move and apply force to the intermediate band.
  • This action causes the direct clutch drum to be held.
  • The intermediate band holds the intermediate brake and direct clutch drum to the case in 3rd gear.
  • This causes the input shell and forward sun gear to be held stationary.
Clutches — Direct
For component location, refer to Disassembled Views in this section.
The direct clutch is a multi-disc clutch made up of steel and friction plates.
  • The direct clutch is applied with hydraulic pressure and disengaged by return springs and the exhaust of the hydraulic pressure.
  • It is housed in the direct clutch drum.
  • During 4th, 5th, and reverse gear application, the direct clutch is applied transferring torque from the forward clutch cylinder to the direct clutch drum.
  • This action causes the forward sun gear to drive the pinions of the low/reverse planetary carrier.
Clutches — Forward
For component location, refer to Disassembled Views in this section.
The forward clutch is a multi-disc clutch made up of steel and friction plates.
  • The forward clutch is applied with hydraulic pressure and disengaged by return springs and the exhaust of the hydraulic pressure.
  • The forward clutch is applied in all forward gears.
  • When applied, the forward clutch provides a direct mechanical coupling between the center shaft and the forward ring gear and hub.
Clutches — Coast
For component location, refer to Disassembled Views in this section.
The coast clutch is a multi-disc clutch made up of steel and friction plates.
  • The coast clutch is applied with hydraulic pressure and disengaged by return springs and the exhaust of the hydraulic pressure.
  • The coast clutch is housed in the overdrive drum.
  • The coast clutch is applied when in 1st, 3rd, D4, and reverse positions.
  • When applied, the coast clutch locks the overdrive sun gear to the overdrive planetary carrier, thus preventing the one-way clutch from overrunning when the vehicle is coasting.
    • This allows the use of engine compression to help slow the vehicle and provide engine braking.
Clutches — Intermediate
For component location, refer to Disassembled Views in this section.
The intermediate clutch is a multi-disc stationary clutch made up of steel and friction plates which are in a module assembly that includes the cylinder and frictions.
  • Applied with hydraulic pressure.
  • Disengaged by a return spring and releasing of hydraulic pressure.
  • Hydraulic pressure is feed through a feed tube in the case worm trail.
  • Uses a bonded piston in an aluminum housing.
  • Applied in during a 2-3 shift event.
  • Transfers torque from the sun gear to the planetary carrier.
  • Torque transfer causes the one way clutch to engage and holds the sun gear from turning, delivering 3rd gear.
One-Way Clutch — Direct
For component location, refer to Disassembled Views in this section.
The direct one-way clutch is a sprag-type one-way clutch that is pressed into the center shaft.
  • The direct one-way clutch is driven by the ring gear of the overdrive planetary carrier.
  • The direct one-way clutch holds and drives the outer splines of the center shaft in 1st, 3rd, 4th and reverse gears.
  • The direct one-way clutch overruns during all coast operations and at all times in 2nd and 5th gear.
One-Way Clutch — Intermediate
For component location, refer to Disassembled Views in this section.
