Transmission have 2000 chevy venture when driving the other day van trany stopped working. no reverse or drive gears. do you know where the transaxle drive sensor is located?

check fluid level in transmission . run the fault codes and look for a faulty TCM or torque converter clutch solenoid / servo

I believe given that transaxles history it has failed

Time for a rebuild

Trans is gone

I would make sure the trany oil is full and if it is then i would say you nned to rebuild the trany or replace it, good luck.

They way you replaced fluid is bad, you should of done a bg service, by dropping the pan theres still oldoil ,the converter is full and the lines and the cooler and inside trany, then when new fluid is added the cleaners in it loosen all the dirt and seend it through the trany, the bg flushes 100% of the old fluid so no mixing of old contiminated and new oil is taking place.

Chevy Venture transmissions have a high failure rate. I suggest you take it in for service.

sounds like reverse let go you need to have trany rebuilt. soory for the bad news, good luck.

First thing is to check the fluid level in the transmission, most vehicles have to be running at engine operating temp either in P or N, check your owners manual. Assuming your fluid is where it should be, that vehicle you have sorry to tell you are notorious for transmission failures, by what you described looks like your going to have to replace the trany or rebuild it, either way its not a cheap fix. My advise if the van is in really good condition put a used trany in it and trade it in for something else. You can look anywhere online about customer/ owner feed backs on 88-98 windstar vans and how bad the transmissions are on those Ford didn't get smart till 99 or 00 when they redisgned the drive train. If you keep driving it the way it is the trany will completely fail leaving you on the side of the road somewhere.
