[rocket1]

I have a 4.9 w/700r4 8.8 w/4.10 &35" tires. jeep runs great until tranny shifts into overdrive & locks up drops rpm's down to 800 leaving me with no power this (novak) stage #2 tranny locks up automatically when it shifts into od they claim this is normal for 700r4 just doesn't work for mine . Is anybody a auto tranny man or can anyone help?

what adapter are you using on that 700r4?

Dont know about the novak, but all old 700r4 ' s have an electrical lock-up. This can be either un-hooked or you can tap into the line with an old g.m., vacuum operated electrical switch, which wouldnt allow lock-up untill partial throttle opening .These were used on the old rwd g.m. cars equipted with a 350 turbo hydromatic and lock-up converter.
