TH400 or 4l80E for High HP Boost.. and gears
I have a glide and the only thing i wish i kinda had was lockup.
And not even for the street, drives great on the street........ but rather for the bigend of the track ..... the lockup of the 80e has me jelly in that one aspect

Only while on a grade which is all the time here in MT.
With a lock up or super tight converter this doesn't happen.
cant outshift the computer. i would not want to sacrifice my rear gear ratio to justify saving a few bucks. i love manually shifting when im street racing or messing around...but with any serious horsepower I honestly prefer to have my hands on the wheel as much as possible.
Ok well ive been looking at RPM 4l80e and circle d converter using factory ecu to control it. SOOO is this the way to go ?? Or anyone got any suggestions to save some money if i go 4l80e?
You can definitely outshift a computer, my th400 does it. Put it in drive and go. Best decision I made with my truck. cruising with 3.42 gears and a circle D 3200-3400 stall Im at 2,900 rpm at 70.

I went the 4l80 route in my build after weighing all the options. It came down to 3 things, lockup, OD and the ability to go full manual or automatic depending on my mood. I grabbed the Circle D 4000 rpm lockup billet converter to go with it.
4L80 in my GTO with a MVB from Jake's Performance and a TH400 RMVB from Rossler in the Camaro. The Camaro is more drag race oriented so I chose the lighter 400, the GTO is more of a cruiser so I wanted OD and lockup and didn't care about putting on a few pounds. Different strokes... but I really do love the OD and lockup for a street car. If I were building the Camaro in current times I would be highly considering a 4L80 but when I built it many years ago a good MVB setup for it wasn't really available.
Well thanks to MightyMouse for the info. Ill be going 4l80e. Im thinking something like a 3.20's gear what do yas think with 8-900 whp? Also I guess since we still got this thread going, converter? Circle D seems to be one of the best lock up converters on the market anyone got any input?
Can't speak for all of them just Jake's but it works flawlessly and it has a transbrake as well. He has a small box that supplies power to the solenoids with an additional wire that is grounded for the brake function. I prefer MVB for the simple fact that in low traction situations I can force a higher gear early and ride the converter out.
