if you live in a cold climate (cold winters) allys don't like cold weather they tend to blow tranny cooler lines, when left parked and running. Last winter many chubbys were stuck due to broken tranny lines and there was a waiting list for replacements. Allys are ok, but a number of tranmission shops are offering build up kits just as they do for the Dodge trannys, makes ya wonder if they are as good as they say? My brother has a 05 3500 2wd drw auto, he hauls rvs cross the states and canada 250,000 miles on stock tranny no problems!?
I have 120,000 on my auto and no issues.
If he has a pile of cash burnin a hole in his pocket go for aftermarket built tranny as Quig19 said, ATS, Suncoast, Level10, Georend (sp) or NADP. He'll be looking at $3000 to $6000 for a tranny, the ally won't be any cheaper by the time you get the right adapters etc.
The "real" tranny experts advise against tranny flushes, best thing to do is simply drain the pan and replace the filter every 30k miles.
