1993 olds achieva-gears won't shift-what sensors on transmission

I have a 1993 Olds Achieva and it will not shift gears. I have changed the tranny fluid, filter, and gasket. Did not help...I want to know what sensors it has on the transmission and if these could be what is keeping it from shifting...I know that there is a speed control sensor on the top of the trans axle. What else could keep it from shifting..where do I start troubleshooting...

Had this problem when I rebuilt my engine. Turns out, that I had plugged back in a sensor that was previously unplugged. There is a known manufacturer's defect on some Achievas where a sensor on the transmission was mounted upside-down. Symptoms caused by this are primarily the car staying in gear (and thus stalling) when stopped, and failing to downshift while slowing down. Just unplug this pesky sensor, located roughly underneath and to the battery side of the throttle body. Be careful, though, because I don't know if running long term in this configuration will lead to transmission damage (although my transmission doesn't show any signs of troubles now that the thing is disconnected.)

Filter or valve problem in the transmission. Transmissions also need regular fluid changes and filter changes and most people do not know this. You can do this yourself, or have someone do it.

Check oil light comes on in my 1994 olds achieva

In the oil pan on your car is a sensor that works the ckeck oil light. It is a two wire sensor that just unscrews. It has probably gone out, or hung up. It has a photo cell on it that can go out. If you replace it you might want to wait till your next oil change because you will lose all your oil. Good Luck
