700r4 slips at takeoff under WOT
Hey guys,
Im having trouble with the tranny and im clueless as to what it might be...
first off, it shifts hard and high into 2 and 3 under light throttle even after i adjusted my tv... I was thinking maybe it had to do with the new 3.42 gears so i thought nothing of it... so tonight at the track when the light turned green i floored it and it stuttered and then just rev'ed to 4k like it was in neutral... I figuered that my carb wasnt perfectly tuned and I went for a second run but this time i took it abit easier than before... It did the same s*** again, run after run... I just doesnt do anything if u go wot from 0 mph
Ive searched on google and I read somewhere that it could be a pressure leak... I want to know what the tranny experts on here think...

Re: 700r4 slips at takeoff under WOT
When mine did that the cause was the (aftermarket
converted)torque converter blew it's thrust bearing and
plugged passages in the tranny's oil circuits with little
filings-had to drop the tranny,take it apart,muck out all
the particles,check the pump,and put the tranny back
together with a good torque converter and reinstall-has
been fine since
There are other possible causes for the slippage too...
