The Jimmy surges when it gets into overdrive like it is going from 4th to overdrive again and again. Could this be the torque converter?

Overdrive problems are common with GMC Jimmy/ Chevy Blazers. The overdrive is failing. The vehicle can be driven in 3rd gear until the problem can be addressed. If you think it's the torque converter clutch, then see if you can locate a square four wire plug on the side of the transmission. Disconnect this plug and go for a drive. If the problem goes away, then the clutch is bad. The vehicle can be driven like this until the problem can be addressed. You will notice a decrease in fuel economy.

2000 gmc jimmy will not go into overdrive?


This is usually a transmission problem (probably the torque converter lock solenoid not engaging, and there can be a number of reasons for this). A transmission shop can sort this out.

My 98 GMC Jimmy accelerates really slowly but once past 40km/h it takes off fine and handles dropping gears going up hills fine. What would it be? Would it be my torque converter?


Sounds like theres no 1st gear. Have you put the shifter in 1 and seen if it went, if so try 2-3 if it still accelerates slowly its probally stuck in 1st or 2nd gear, when it goes in to the 3 rd gear it will accelerate normally, also in 4th (OverDrive)

The jeep grand cherolee lared 4WD V8 won't go into 4th gear


Possible you have a simple problem such as a bad solenoid and or maybe some kind of engine coolant temp sensor problem.The v-8 engine in this year did not have true computer controls, it did have a solenoid for lock-up torque converter and a solenoid for overdrive.It was basically just and old tech hydraulic transmission with two solenoids.Most likely unless the transmission has been rebuilt properly before you are at the beginning of the end.No overdrive in this year model usually means the clutch in the torque converter has shredded and stopped up the cooler and melted the overdrive unit.I would have someone to pull diagnostic codes and see if there is anything stored.You may want to remove the transmission pan and inspect for debris in filter.Good luck!

Transmission light on. Rpm go to 3000 when I'm doing 55mph.it not going into 4th gear (overdrive) what's wrong with my truck?


It seems as though your electronic "lock up" on the torque converter is not actuating. TCC lockup/Torque Converter Clutch lockup.

Car pulsates when shifting into overdrive.


Need to verify if its overdrive or the torque converter locking up. If its when it engages overdrive these transmissions are noted for the 4th clutch hub splines stripping out and 4th clutches slipping, Need to verify. Have vehicle checked for trans codes, a code P1811-long shift, max. adapt could be many things. If it just when the torque converter locks up it could be the converter itself or an EPC solenoid sticking especially with a P1811 code. Either way it is proablly handled best by a professional.

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

When my 95 comero 6 cyl trys to shift in overdrive it shakes shutters i have too continue to accelerate for the car to run rite


common and not good, need to verify whether its going into over drive or the torque convertor locking up which feels like a 5th gear. if its when the torque oncverter locks up then it will need to have the torque converter replaced and the valve body repair/replaced. if its 4th gear then it soounds like yoou got a slipping 2/4 band that needs diaged and repaired.

1996 GMC Jimmy will not shift into overdrive.


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.

My 2002 trailblazer is making a noise when I go over 45 mph and appears to not be going in gear quickly at that speed


Check your transmission fluid level and/or have the fluid changed. If problem persist have a transmission professional at a dealership or transmission shop service it.
