Heres the problem: My 700r4 will not shift into OD, and 2nd rearly catches, and if it does it is upwards of 5,000rpm. 1st and 3rd still pull strong. Doing a search, it seems possible that it is the 2-4 band, but I want to make sure before I pull it out and drop it off as I don't know a lot when it comes to the inner workings of a tranny.

Also, what could have caused this? My fluid is beautiful, though there is a slight leak from the tailshaft. This is on (accourding to the friend I bought the car from) a Pro-Build 700r4 w/ a 2,800 stall. TV cable is adjusted properly. Though I do have a B&M shifter. Deffinetely has a corvette (type) servo.

I just started prom tuning with autoprom, and really started gaining a lot of tq w/ the tuning leading up to the tranny problem, so maybe that has something to do with it?

Thank you for any advise
