just a thought.

Yah that would be interesting to find out, but i'm not about to take **** off my $2000 tranny to see if i can hold a gear, i never really need it to do that, i was just more curious. I don't think Chuck would like that if i sent him back a broken *** tranny and want it rebuilt even though i fudged it up, haha. Not saying it would break it, but it's perfect the way it is, i just wanted to see if i could tune it to hold. I have a good buddy that i can try the same thing i tried on my truck, see if i can tune it to hold gears on a STOCK tranny.
