Re: Trans Failure
I got GM to pay for my first 4l60e. It went @ 48k. My second one went @ 110k. I'm now on 146k, and it's all good. I had the last one built to the hilt, 10 clutches in the 3-4 band, HD servo pistons, shift kit, larger pump, and stainless sprag. As well as an extra clutch in reverse. Cost me about 1400 bucks. Find a performance shop, most of them will build them pretty good is you ask.
PS-I also bought a oversize pan from summit for 100 bucks. It's aluminum, and holds 2 extra quarts, don't forget about a front tranny cooler too.
