Re: 4L80E & TH400 Tech.

So now that my 4l80e is built... how about a slightly different kind of topic.

Proper "care?" of a 4l80e in high horsepower use. Not so much change the fluid etc, but how to treat it.

A few things I have read:

-race in 3rd not overdrive because it engages the front band? and 4th doesn't like high power full throttle shifts

-don't shift into neutral at high speed to prevent over spinning the direct drum

-there was something about how to do a proper burn out but I don't remember what it was

Anything else you guys can think of?
