Best kind of automatic transmission for high horsepower (1800+HP) - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Hey guys, as the name says I was wondering what the best kind of automatic transmission for ridiculously high horsepower numbers, like around 1800-2000+ horse. I'm going to be a building my Camaro that's gonna have that much power and the transmission is screwing me over because I can't find one. Thnx in advance for the information and plz be civil in your posts.

Guess I should also mention, I'm specifically looking for a 6-speed auto if possible but will do with 5 or more gears.

TH400

Could be my inexperience & lack of fully understanding of how autos work but is there a six speed variant of the th400 other than its grandkid the 6l80e which I was was already looking at but the highest rated one I found was 1,200 horse from PATC. Will google for information tho.

You can make a TH400 a six speed by adding a gear vendors overdrive.

They offer transmissions for 1500+hp and it mentions 2000hp+ combos as well.

Out of curiosity, what are you doing with the car you want 1800hp+ and a six speed auto, besides going REALLY fast?

Its gonna be a combo DD & drag car

TH400 is basically your only choice for that power.

Yup, that or a glide. Your at a minimum 1000hp off of what any 6 speed can handle, don't care who builds it.

Yeah TH400 with about $5k or more in just parts and if you have to have a 6 speed throw a GV on the rear like Blake said.

Well if it makes a difference, I'll be adding a trans cooler from Mishimoto to the setup, will that help a six speed or will it make no diff?

You're looking to make 2000hp and talking about running a cheap a$$ trans cooler.

Trans cooler don't necessarily increase holding power. It's the decrease in trans temps that help it live and live longer.

What are you doing for rear? That's alot of power.

Rat · 01-07-2015, 09:53 AM

If your talking 1800rwhp you better look at a Glide. Power Glide or a Turbo Glide.

I'm talking 1800+ @ the crank, altho some demented part of me wishes it was @ the wheels, tho it could be close because i'll be replacing the OEM motor mounts & bushings with ones from BMR Racing, altho with the motor mounts wont be using the poly will be using the pucks & adding sub-frame connectors from Granetelli Motorsports. Here are links to both:
