Car will just slip into neutral . Doesn't matter what gear it's in . Can only drive maybe 100 feet before it does that. Have to restart car for it to go into gear again and can go another 100 feet. Code said TCM was bad. We changed that and car still does it

My car has 191000 miles.
My car has an automatic transmission.

Hi there. Assuming you replaced the TCM (transmission control module) with a factory part, a transmission shift relearn procedure should have been performed. It could be that you have a TCM connector or wiring issue if the same code has returned.

Time needs to be spent to confirm the diagnoses. It could be you received a faulty TCM. A low transmission fluid level could cause the symptom of feeling like the transmission slips into neutral. The low transmission fluid level would allow the vehicle to move a short distance, until the filter could no longer pick up fluid.

When fluid drains back into the pan, the filter can again pick up the fluid until the fluid level goes below the filter. I recommend having the transmission slippage inspected and diagnosed by a certified technician, such as one from YourMechanic.
