2000 Dodge Grand Caravan Sport with 3.8L and 76.5K miles. Transmission fluid was changed at 60K miles. Getting two check engine codes:
1. P0700 (General Transmission problem)
2. P0740 (Torque Converter Clutch Circuit)
My Indy thinks its something in the tranny proper.
For that matter, so does the dealer (2nd opinion).
After clearing the codes, driving above 50 mph for more than a few miles causes them to re-log.
I do have an extended warranty on this, so money is less of an issue.
My primary concern is the proper diagnosis and repair of the problem with the best parts available. That being the case, should I go with my Indy (who seems fairly competent and he said he could do it), a transmission shop (like AAMCO or something), or the dealer?
I had read somewhere that someone thought the non-dealer tranny shops used _better_ parts than the dealer. This could be a pump or clutch fix or a full rebuild...or even a remanufactured one. I have little or no experience with automatic transmissions (my first car, a '75 LTD doesn't really count, making the Dodge my first one).
Any input would be greatly appreciated. BTW, I live in Phoenix, Arizona.
