01m trans not aways in gear when starting off from a stop.
When I come to a stop or slow down amost to a stop and then try to go again, the trans seems to be out of gear. The engine revs. up and suddenly the trans will bang into gear Also would like to know if the trans. module control is also the same ECM used for engine.

Trans output sensor?? speed sensor maybe? Did the speedometer start working? This is where you have to start. Important feature for shifting. This is electrical and checking wires for continuity. If it always goes in gear and drives, I would look hard at replacing the solenoid package. It's on the front side of the transmission. Costs around $300. You have to remove the cooler lines, a sensor, and 3 bolts to remove it. Clean it, around/behind it first. You absolutely do NOT want any dirt getting in the holes on the transmission.
1999 cavelier manual trans: My son was shifting his manual trans really rough (ramming through the gears to try to beat someone out at a light) and ended up not being able to put it into anything but 3 and 4 (straight up and down). We noticed that the shifter cable, that actuates the position of the arm on the transmission, had pulled away from a "c" clip and was not held into place about 8-10 inches down the cable away from the trans. The cable needs to be secured into that clip in order to let the wire inside move the trans. lever to shift. Otherwise you will be stuck on what ever "rail" your trans is on at the time of disconnection. It would be the first thing that I would check.
It sounds like you need transmission fluid and filter change. This is one of the most overlooked maintenance items. It should be changed every 50k (30k if you tow a trailer) The delay in engaging gear is sign that trans fluid is tired or REALLY cold. In cold weather this is a normal symptom on cold morning starts but goes away when warm. I'd get it changed and soon, before it turns into a $$$ repair.
Hi, Four wheel drive is a traction devise. Not a braking devise. So, no it will not help you stop faster. That said, on slippery conditions when you let off the gas the extra, "traction" will help slow you down if you do not slide. Hope this helps you out. Wayne
I think it's done for. How many miles do you have on the car?? This is the 4sp auto right ?? The average life of this trans, the 01M is around 140,000- 160,000 mi. Some more, some much less. The only thing you can do-
1st check to make sure floormat isn't in the way of the accelereator pedal travel
Put key in ign.
Turn to on position BUT DON'T START IT
Right after you turn the key press and hold the accelerator right to the floor and hold for 7 seconds.
Release pedal and turn off key.
This has reset the fuzzy logic of the trans. No promise this can make it better though, and no promise that it won't make it worse. The first 10 miles or so might be a bit rough because the trans is trying to re-learn it's job again.
The 01M is very expensive. $4000-4500 average to replace.
OK this is a very common problem. there is a 4 pin connector on the trans. (just below the air box area sometimes blue or grey)(in a shape of a box) that is your TCC soleniod switch connector. just dissconnect that and see what happens. if your problem stops then you need a TCC solenoid. what that does is it locks up your converter at 40mph+ or HWY speeds to save on gas. another way to test it is when your slowing down and it feels like your driving a stick shift and it wont get out of gear and stalls. if that is what is happing thats your problem. just dissconnect it if you want but i remomend getting it fixed. DO NOT REBUILD TRANS. many trans shops try and pull a rebuild on this.
