Read the stickies. Didn't find the info I was looking for. Want a write up, or directions to info about these trannies. What is a "built" 4L60E? How much do these trannies cost (W/ general install cost range if possible)? What fails on the 4L60E? P.S. Will my 4L60E hold up to 450hp? It's a dd, and I drive it rather modestly. No track visits, no canyon carving(too many speeding tickets), etc..I've got a vig2800. Tranny cooler and shift kit(will they help?) My trans seems fine now. Hard shifts ever since the stall and tune. Is that bad? Sorry for all the rookie ?s. Thanks!
