BEST TRANS for turbo build
The Best V8 Stories One Small Block at Time
whos your builder that will do a th400 for under $1000? cause that is cheap!
The difference between a glide for a 3500+ Lb car at 1000 rwhp and a TH400 is price. A $1000 glide will not live long in that environment whereas a TH400 in that price range can last a very long time. It would cost about $2K to make the glide as strong. But I'd rather have the $2K glide if those were my 2 choices.
So 3rd gear in a th400 is the same as 2nd gear in a glide. The only way you will get better rpm on the highway is with an overdrive, or by using the th400 like a glide. Using 1st, and 2nd at the track, and 3rd as the overdrive, but you would need a low gear in the rear end.
If the car has to be driven on the street alot, i would say 4l80e. But it will cost double what doing a th400 would cost. My trans built for 1400 whp or so was 1300 bucks, with a warranty.
Good luck bud.

who built your th400? are you running a t-brake?
And if you have a low CR engine like i do (8.7to1). it hated 6th gear alot you had to be moving faster than 85mph to use 6th. but in this state there are to many potholes to be on the look out for to use it anyway LOL
so if you want to go auto and you like to drive your car alot like i do, save the money or hunt around for a deal, they are out there. and just do a 4L80 and be done with it
and for the die hard M6 guys my car is WAY more of a handfull with a auto. than when it had a M6. it hits the tires way harder
Ive bought prob around 7 rossler trans.....never regretted it...all th400's with brakes or 4l80e's.......Carls 4l80e is hands down the best trans Ive ever used. And I ve used......100's.....The 4l80e is around 4000 or up....
