I am having a problem with this tranny....When cold it works beautiful...as it warms up the convertor attemps to lock then rapidly unlocks . After it's fully warm it just doesn't even try anymore...sounds like a bad pressure switch or something....

I took it to the tranny shop and the guy said he could not access the ECM (88 chevy truck) so he talked me into this...

He said he could install a check ball in the tranny (where?) to hydraulically lock the covertor as soon as it shifts in 2nd gear....

Boy it works...But I don't like it...so I want to do my mod....just lock it when it hit overdrive ...So it's only locked when in overdrive....

Question is...where did he install that check valve so I can take it out??? I guess I could ask him but I don't want to seem picky....

Really I just don't want to pay another $ 60.00 to take it out...

Thanks.........Doc
