4th gear failure is a common problem with this transmission, assuming it is an automatic. You should have the vehicle checked for codes by a qualified repair center with the proper scan tool. Also, check fluid level and condition. More often than not, the trans loses 3rd and 4th gear, as these are working off the same set of clutches. 3-4 clutches apply in 3rd, and when the 4th shift is made the 2-4 band applies giving you overdrive. If you have no engine braking in manual 3rd, you definitely have a mechanical failure, no 4th could be an electrical, or mechanical fault.

1996 4l60 shifting in and out of overdrive


Time for an overhaul on the transmission or replacement. 4L60's are notoriious for the overdrive clutch to give the "hail mary".
Try replacing the transmission filter first.

MY 1996 GMC JIMMY 4 WHEEL DRIVE HAS ALL OF A SUDDEN WHILE DRIVING DOWN ROAD LOST 3RD AND OVERDRIVE. HAVE A CODE PO700 WHAT CAN THE TROUBLE BE?


P0700 means EATX Controller DTC Present. That means that there is an internal fault inside of the transmission control module, so you'll need a new module.

I have a 1996 Jimmy 4x4 vortex engine, the tranny will shift from overdrive to a lower gear all by itself while going down the highway causing the rpms to go up over 3000. I pull over and shut the engine...


Hello,

A couple of things come to mind that can cause the issue you are having;

1. Make sure your transmission fluid level isn't low.

2. If your transmission fluid hasn't been changed in a long time, you could have some deposits
built up in the valve body, or the screening could be partially clogged.

3. You may have a faulty shift solenoid/shift motor.

Number 3 is most likely your problem.

I hope this helps you.

My 96 jimmy studders and does not want to change to the 4th gear when in drive,when in overdrive it wont change to 5th gear(overdrive)will the tps sensor do that


Make sure the engine is running right, sometimes they wont shift if the engine is missing or losing vacuum. Sounds like the computer system is sensing there is not enough torque to shift into the higher gears so it is preventing it. This could be caused by your engine not running right under load, bad gas, bad plugs or something that is causing your engine to miss under load

1996 GMC Jimmy will not shift in to first unless it has sat for a cupple hours


You'll have to connect the vehicle to a scanner and read the pressures @ the pressure control solenoid and the 1-2 shift solenoid to narrow down the problem.

I have a 1995 GMC Jimmy with auto trans., it wont shift into 2nd gear only shifts into drive when I get up to 2700 RPM and let off the gas and wont shift into overdrive at all. Does anyone know what causes...


Your going to have to get the Jimmy scaned before youhurt the transmission, It sounds like it's on a Limp mode which can range from a tune up to a bad ground. Good luck.
