How Much Love 4L80E I am thinking about putting a 4L80E in my TA because it will mostly be drag raced but i also want the over drive. originally i wanted a TR6060 but my track times will be all over the place. And it would be a bit slower than the A4. My car will be around 950hp at the crank.
For those who have done it or heard about it, how much love do you have to give the trans tunnel? I am really not fond of banging it out and a 4L60E is out of the question.

Gordon,
A couple people down here have done the 4L80E conversion in there 98+ F-Bodys.
One is a 750 RWHP sc'ed set-up and the other is big stroker motor set-up + spray. A company here in Lauderdale called ATF Transmissions, who builds alot of 6-7 second drag cars, did them both and tuned them.
They are working great from what I hear. Daily drivers and track cars.

Its a very simple swap and you already have a 4l60 even simpler yet.
As said you have to cut out area where that big frakin 4l80 main plug comes out. I used 90 degree fittings or you would have to do some BFH or notching where the trans fittings come out.I did modify the 90 degree to have the long tube the factory ones does be sure to do that properly if you do change to 90s.
My RPM 4l80 came pretrimmed with the ears cut off and not sure if any other grinding on there. It was done and repainted before I got it.
It fit fine.Since my car has aps twin turbos I had to further do some clearancing for the drivers side downpipe and for my wastegate bolt on passenger side easy enough.
I got hptuners segment swap to run the new trans. Got flexplate from speed inc ,got converter from yank for 4l80. Got lokar short dipstick by accident and then ordered the longer 36 inch one its much better. Got bmr crossmember with torque arm mounted on it. I had to use conversion harness you don't well just do the 4l60 to 4l80 part.
I wanted overdrive and trans to take the big power..maybe 1000rwhp sometimes and likely around 800rwhp daily driving.
Find out next season how it does for me. Car is 99% street but will see dyno and track a few times before track retirement but it will still get driven hard off track on occasion.I don't baby my cars.
Another viable option because the 4l80 is so much money is a turbo 400 with maybe 3.08 gears. Still can work good track or highway but personally hate gears much lower than my current 3.54.
