Hey TA

I went thru the same dilemma myself this past summer. I swapped a RJ 502 into my GMC Safari, and really wanted to go with a 700R4. However, after talking to the boys at PATC, I decided to listren to their advice, as qwell as the advice of a few friends. Truth be told, I'm sure the 700R4 would hold up, I just don't know for how many months it'd do so. It all comes down to how you drive. PATC told me that with reasonable driving, I'd be good for about a year. Not worth the risk if you ask me...
I went with a PATC built-up 4L80E and a stand-alone Compushift computer. Tranny is a charm, and the computer is still capable of amazing me after 3+ months of driving. Matter of fact, I just got back from a 4000 mile trip with the truck, sorta like a "real" shakedown run LOL
