SOURCE: GEARBOX WONT GO INTO GEAR

hi from uk could you please give a little more info ? what make/model car ? has this problem occured suddenly? has car been layed up off road some time prior to this unable to select gears ? this problem sounds very much like the clutch drive plate is either stuck to flywheel hence question above ? or it is sticking on primary/spigot shaft for some reason and failing to disengage drive to g/box? how does clutch pedal feel ? you might try selecting 2nd gear with clutch fully pressed and h/brake on then try starting engine if engine starts ?runs then put slight revs on and slip clutch a few times this may work if plate is sticking? if you come back with update may be able to advise further

SOURCE: Replacing the clutch on a 1998 Saturn SL1

It is very difficult for you to disengage the clutch by hand or with any leverage you can get outside the transmission. There is over 200 lbs of force clamping on the clutch disc.

If you replaced the clutch and took the slave cylinder out of the transmission without putting a brick under the clutch pedal or disconnecting the pivot arm from the pedal then you ruined the hydraulics. Buy a new PRE-BLED system from a local auto store. Generally this is the problem.

Either that or the clutch fork is bent or you installed the throwout bearing backwards (or simply fell off the fork which is not all that uncommon).

I have a 1998 Dodge Dakota 3.9 with a 5 speed. I am having difficulties with the clutch and am trying to figure out if it is the clutch needing replaced or if it is the hydraulics.


Bad hydraulics (leaking/spongy) and worn out clutch have opposite symptoms. If the clutch does NOT ENGAGE - get the vehicle moving - you probably need to replace the clutch and/or pressure plate.
If the clutch does NOT DISENGAGE - you can't get the transmission into gear, or there is difficulty or grinding when trying to shift between gears - your hydraulic system is not moving the clutch release arm far enough to disengage the clutch.

2002 toyota celica clutch is there an adjustment or is it hydraulic?it also smells like burning clutch?


its a hydraulic clutch. the burning smell could be a sign that the fluid in the master cylinder is low and there isn't enough pressure being applied to the flywheel, causing the clutch to slip. if the clutch disengages at near the end of the pedals "throw", as you disengage the pedal, than its a sign your clutch plate needs to be replaced. but to me it just sounds like a hydraulic pressure issue.

The Clutch disc and Release Bearing for the TD4-Freelander, were replaced recently. The Pressure Plate was still in a good condition.Gears difficult to engage.Please advise.Tks.John.


Most likely still has air in hydraulic clutch slave system. Many transmisions will have dificulty shifting if clutch doesn't full disengage. If air is in system it won't allow full disengage thus difficulty in shifting even possible grinding gears

Hydraulic clutch is not disengaging, when put into 1st gear the engine conks out. Replaced the master cylinder and bled the line - still conks out. Do I need too replace the slave cylinder or what?


as per your description problem not clutch since able to start in gear and drive without stall problem sounds more like a fuel delivery not the clutch

Clutch is sticking and wont go into any gear


if you have just replaced the clutch the the plate is in back to front and the hub is hitting the flywheel bolts.
if you haven't then other problems can be bad clutch cable not fully disengaging clutch, air in a hydraulic system or oil / grease on the clutch plate ( normally indicated by a shuddering or slipping clutch

2001 CRD Grand Voyager - clutch won't disengage.


Is there any fluid on the ground near the transmission? It's possible the clutch actuating cylinder has failed. If it was air in the line you would have noticed it the day you got it back. The master cylinder is on the firewall next to the brake master. You can add fluid if it's low. If it's empty then there may be a loose fitting or the bleeder screw on the actuating cylinder may be loose too.

How do I adjust the clutch in my 2005 F-250 Superduty with a 6.0L Diesel


The clutch on this vehicle is hydraulically operated and as such there isn't any actual adjustments that can be made. A worn clutch disc can cause the clutch not to engage until the pedal is very high up while a problem with the hydraulics can prevent the clutch from fully disengaging which will cause the gears to grind when trying to shift into first or reverse. Hope this helps a bit with your question.

Clutch doesn't want to disengage when the pedal is depressed. Oil level seems fine. Runs through the gears fine when the engine is off. I may mention here that it is a manual transmission. The problem...


It sounds like your hydraulics might have gone bad. They are no longer pressing the pressure plate hard enough in order to disengage the clutch disc from the flywheel.

If the pedal feels any different this may be an indication that the hydraulics are bad. Otherwise it could be the pressure plate fingers are worn enough where it won't have the spring pressure needed to push on the outer diaphragm to disengage the clutch.

Also there is no "oil" in a manual Saturn transmission, it is ATF, the same stuff you put in your automatic transmission.

02 dodge 2500 clutch not releasing


An hydraulic clutch line can be bled. There should be a bleeder screw on the cylinder at the end of the line running from the master clutch-cylinder.

My 2001 lincoln ls wont go into 4th or 5th gears. Took it to a trans shop and they recommended a rebuild for 3000+ dollars. But Ive been reading that alot of lincolns with the same problem getting err


call your dealer to get an estimate too.

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.
The Intermediate One-Way Clutch is a sprag type one-way clutch.
  • The Intermediate One-Way Clutch connects the intermediate assembly to the input shell and sun gear assembly in third gear.
One-Way Clutch — Low/Reverse
For component location, refer to Disassembled Views in this section.
The low/reverse one-way clutch is a sprag type one-way clutch.
  • The low/reverse one-way clutch holds the low/reverse drum and low/reverse planetary assembly to the case in 1st and 2nd gear.
  • In all other gears the low/reverse one-way clutch overruns.
