Just to let you know that I just got my care back from the tranny shop. I had not had a problem at all and just the other night after picking up my son , got in my car and it hesitated to go in reverse but it and it bucked real hard twice. Did a little of the same ..but anyway...the tranny place has to replace the lock nut on the main shaft. Remove side cover of transmission, replace self loking nut on main shaft ..nut came lose ...$320.00 So I was very happy I didn't have to have a valve job, sylenoids replaced or rebuilt tranny.

2001 hyundai elantra goes in2 reverse but won't go backwards all other gears r perfect


Most automatic transmissions have a separate belt for reverse and all forward gears, The reverse belt is commonly lighter duty that the forward belt (some Chryslers were affected so much it was advised to not shift into reverse until the engine had warmed up and the automatic choke idled down) Thus your car would be in "reverse" but with no motion getting to the gears.

In turbo hydro 700 why would forward gears make the rear wheels go in reverse


Your differential is upside down. Ford model T's had the same problem. It was possible to mount the rear axle upside down which made the car go forward in reverse and backward in forward gears.

The reverse is going faster than forward


do you mean you have four reverse gears and only one forward gear or do you mean your rpms aren't going up as well in forward as in reverse

All forward gears work excep the reverse any ideas?


It sounds like you have the Auto box and in it you have 2 bands 1 is the forward and the other one is the Reverse ,so if your forward gears are working ok then the fluids ok so its either the reverse Pump or the Band which drives the reverse gear is worn or buggered .
So your answer is to go to the AUTO MATIC shop and get them to check it out{ IT MIGHT BE THEY CAN ADJUST IT IN TIME IF NOT TO BAD}. AND THAT WILL SAVE YOU A LOT OF MONEY.

98 vw beetle wont go in reverse


I have a 1998 and I just confronted the same problem. It seems to take like 1 gear in reserve and like 2 gear in 1 gear. Any thoughts? I don't really it should be the transmission since it still works going forward in 2 different gears. Thanks.

The reverse gears are not working.if you put the reverse gears it will accelerate infront instead.what do i do?


It sounds like the reverse band broke. Typically with automatic transmission when you put the transmission in reverse a couple things happen. Usually, the forward clutch engages and the reverse band engages holding the reverse drum from turning, which causes the planetery gears to make the vehicle move backwards. If the band breaks there is nothing told hold that drum from turning and you have a forward gear. The bad news is the trany is going to have to come out to be repaired and usually the reverse drum is one of the first things to go into the trany, so it has to be completely disassembled. Take it to a transmission shop have them check it, hopefully it's something simpler.

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.
