Auto trans stalls in gears

Could be alot of things.

I would just reset the eec by unhooking the battery and seeing if it continues.

Then I would check for vacuum leaks.

Then I would do voltage tests on all the sensors.

Then I would check compression on each cylinder.

Then I would check for exhaust leaks/obstructions.


If you got the IAC from AutoZone, that's probably the problem. Never get AutoZone electric components.
