Where can I get information putting in a 4L80E in place of a 4L60e?
As of this morning, a conversion is what I'm thinking. After having mine "built" by a reputable builder, lost 3rd after about a month of on/off driving. Too many times, as far as I'm concerned. Ever since I got into the LS swap realm (10 years ago), 80E conversions have been proven to last under high powered applications (500+hp/450+ftlbs, bench) better than most "built" 60E transmissions. I'm at that crossroads now. Read the referenced stickie earlier this morning.
Well, you could get a manual valvebody for your 4l80e, that would elminate the need to get a standalone controller, which seems to me would be right in the 1000 dollar range if you wanted to have the ability to program every aspect of the transmissions behavior.
Its not going to be cheap, and while i guess the 4l60e is kind of weak, I thought performabilt really made a nice one (they have their black edition stage 3 or whatever, 1000hp+ capacity), but a weak design IS a weak design.
I'm not going to argue, but how long a transmission lasts under stock power on a detuned car is not relevant. They last a long time it seems. Under stock power. Put a load on them AND don't take care of them and they will die early. And even earlier if you add power. More line pressure is your friend, as are frequent fluid changes and extra filtration. The slush box tuning kills them even sooner yet.
I bet a tuned and programmed 4l60e will last 300k miles or more buckled to a stock b body LT1.
This thread is about power though. I know people build 60e to withstand 800+hp. Stock is a different story.

I just talked to the guy a PB. Explained to him what I've been having trouble with (concerning my "built" unit). He was truly concerned with giving my builder the benefit of the doubt (after telling him about the build), and offering suggestions to assess. Truth be told, I'll get the unit repaired (since it's under a 12k mile warranty, with less than 1k on it). However, I may repair it, and just buy another unit from PB if the next repair fails. I don't have the patience to R&R every month. So, THANK YOU to the guy at PB, whom answers the phone after 3pm ET (when the shop guys quit for the day...

The new 4L75E parts are out making the 4L60E series a lot stronger.
They are fair and easy to talk to.
I am using their Stage Two for drag racing and love it.
Using another for the tow car and keeps breaking..
So looking at PerformaBuilt one designed for Towing..
Yes, have had 80E in wife's SS for 3 years.Has anyone here actually ran a 4L80e on the factory computer?
I would love to know details.
