Best Transmission for a 4x4 Modified Puller Truck

Post by TorqueZilla » Fri Mar 06, 2015 3:31 am

Building a 6200lb 4x4 Modified Pulling Truck and am looking for suggestions on what to use for a tranny. Obviously it needs to be automatic. Neutral Park and Reverse. CANNOT be a drop box/transferable type transmission. Anyone have any thoughts?

Are you saying it needs to be an OEM tranny? Also, what brand are we talking here? My brother and I have run TH400s for years, very tough especially when only using first gear.

Yes, the TH400 is the best OE automatic. It's capable of living behind well over 1500HP properly built. ATI has the best parts and torque converter, had plenty of success with it.

A Properly built c6 will take 1500hp with stock parts and live. 400 needs lots of dollars to survive at that level

727 will live behind any Mopar
and
there is a reason the blown BBC chevy's ran them
so it looks like any of the 3 speed big three can be made to work

Can you define properly built for the 1000-1200 hp bbc engines?

Thanks

For that use, you'll need the big severe duty intermediate sprag, the correct severe duty clutch packs, a steel forward input hub, and a good full manual valve body, with a deep pan and an Allison style brass screen filter. I'd strongly suggest a transmission shield. There are upgraded shafts, input, intermediate, and output, that could also be used. You can get all of that from ATI Performance Products, and they make the torque converters as well, I use their products almost exclusively. Consider that torque converter failure can severely damage both the transmission AND the engine.

Thanks, getting ready to head down the 1100 hp + BBC route in pulling so I've been doing my home work.
