Bad powertrain mount or worn CV joint or high idle speed or torque converter problem.

Your trans fluid could be low or your trans is on it's way out the door.Some cars,reverse is the first to go.Good luck.If the fluid is not low,drop the pan replace the filter and put a trans additive in when you fill it up after the trans service.The best additive is called trans-x.

A "speed" sensor can affect the shifting of the trans.

The most common problem I have seen is a failed motor or trans mount.

Do you have a check engine light. I have had problems with my 01 Lanos and the check engine light came on and it was the oxygen sensor so that may be your problem

first check fuses,then bulbs,then reverse switch on trans mission,it might need replacing,its screw into your transmission.

I'm having the same problem with my trans. I've read online that these trans have a lot of problems with the input and output speed sensors.

Rev servo inop for some reason. Takeit to the trans shop.

Check transmission fluid level if full you have an internal trans. problem Check transmission fluid level if full you have an internal trans. problem

hey m8 check your trans fluid as i had the same problem there was no trans fluid filled it up and away it went

Maybe. If the trans is messed up enough it can drag the engine down. But this is very rare to the point where I would bet it isn't your problem

Your reverse light, neutral safety switch has a problem, remove it ( right side trans ) and take it apart ( 2-300 bucks new ) clean it and adjust it.

There are sensors inside the trans, outside the trans, and on the engine that will all affect shifting.

You need to have it checked for trouble codes. The trans computer defaults to 2nd gear when a problem is detected.

The rubber isolators in the engine mounts have worn out or the CV joints in the drive shafts are worn out.

There were three trans mission options. four speed five speed and 10 speed power shift with 2 reverse.

Is it an automatic? Time for a new transmission... If a stick and 1st, 3rd, 5th are ok, then you have a possible shift cable problem. You should be able to see them on top of the trans. If everthing is moving properly the trans has an internal problem.

On a 5-speed I'm pretty sure it is right next to where the shift tower gets bolted to the trans. It is a little ball that rides on the shifting rail. Should be pretty much the only sensor that is on the top center section of the trans.

Line pressure problem in trans due to low fluid, bad pump etc. Check fluid first.

It will default to second whenever the trans computer has detected a problem and set a code. You will need to have the transmission codes checked. It could be electrical or an internal trans problem.

because you have a problem with your transmission and it is now in limp mode.it is probley shifting hard into each gear to.. need to flush trans and reset computer
