New-to-me 2013 Grand Caravan RT with 119,000 miles. After the van has been driven around 20 minutes it will start stalling inconsistently at stops, prior to this it runs great before warmed up. Just prior to stalling the RPMs bounce around 500, and if shifted into neutral quickly the van will not stall and I can idle fine at the stop, but when shifting back into drive it will stall unless gassing it quick. Also when it dies, it will start again fine in neutral or park, but when shifting to drive it will want to die again. There are no check engine lights on. Sometimes it will do it every stop, and sometimes 1/10 stops. In order to fix this the previous owner had the transmission, torque converter, solenoid block, and TIPM replaced recently which did not change anything. I have a new MAP sensor on the way. What else could be causing this problem? Thank you so much for any advice.

Rebuilder didn't have a warranty? That soon after most places would cover it. Some places might even if they didn't have a warranty on it just to keep the customer happy and their reputation untarnished, since the issues were almost immediate. Sure worth a shot.
Agreed, it doesn't seem likely that a new transmission would have the same issue as the old if the problem is in the trans. PCM and/or wiring are the most likely causes.
If this were a GM product, all that goes out the window though. Their transmissions can eat themselves in days if not correctly programmed. Went through 3 reman trans in a month on a G8. First one lasted a weekend and had as much shavings in the pan as the one we took out, second one had shavings in the pan from pre-shipment testing so we rejected it before install, 3rd one finally worked, but took many attempts over 3 days to program it right.

On that one the vapor canister solved it. All other parts of the EVAP system were performing as they should. The rich purge fumes were causing the PCM to dial back the fuel enough that it couldn't run. The truck would run fine up until the purge opened. Oddly enough it threw a lean code while in the shop.
