Whats the best price for a 4l60e to get built up strong enough to not have to worry about it, and one that maybe shifts stronger.

And who does them.

Throw me some ideas since I found out you cant change your tranny fluid or else your tranny dies????

Thanks,

Try these guys, I have heard nothing but good things about them. Theya re probably more expensive than most places, but it will be worth it in the long run.
