2008 grand caravan stalls when shifted into Drive. I am eventually able to get it going with some acceleration and it drives fine until it goes back down to first gear at a stop. Replaced torque converter. No change. Performed pcm flash and quick learn. No change. Any ideas?

 

Dirty IAC, throttle body, poor state of tune. Sounds like you are just throwing parts at it. Check engine light on?

 

It had a torque converter code when it was brought to me with the new part. I replaced the torque converter and cleared the code. Drove it several miles and couldn't get any codes to come up. I'll probably run a flight recording this weekend and see if anything pops up.
