Original trans, neither I nor anyone else has worked on it.
This appears to be a straightforward innternal failure. I plan on obtaining an exchange rebuilt. Question 1) Does the complete drivetrain (Cradle, engine & transaxle) need to be dropped out per service information, or can the cradle be droped and the transaxle be removed, leaving the engine in the van? Question 2) It appears a PCM relearn/flash needs to be done after transaxle exchange or rebuild. Does this need to be done at a dealer, or can an aftermarket scan tool do it? I have access to a Mastertech & Launch.
