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.
Go with your best option, but here's my experience.
After replacing about 15 transmissions and living with the aftermath of various shops, I've found that overall, new car dealers rarely have the shop expertise to reliably perform transmission repairs. Swapping in a new tranny, sure. As for national transmission repair chains, it's so hit or miss as to make me dismiss them altogether. Independent shops are great, but you want the backing of a nationwide warranty on their work in case you decide to relocate to Grand Rapids. So-my faith is in a reputable independent transmission specialty shop. How to pin one down in the sunny desert South is your mission.
