Tremec TKX 5 speed behind Hellcat engine?

[Chopper1967]

Hello all,

has anyone leaned on a TKX manual trans hard enough to know the strength of this unit?

Just brainstorming trying to figure out a drivetrain combo, I would like the TKX for the simplicity and lack of mods to the floor to make it fit.

Thanks!

Its advertised to take up to 600 lb ft

I’d stick with the advertised torque ratings because we all know even with those they still let loose sometimes..

Check on cryogenic treatment. Not sure how much capacity it adds.

I will be putting one behind a 800hp NA G2 528 Hemi so I guess we will see.

Awesome!! Can't wait to see the results.

Here is a TKX behind a 6.4 crate Hemi using Holley mounts in a 67 B Body. Height of shifter "tower" and contact with the drivers side of tunnel result in more mods being needed than I hoped. I think I would get the tranny needed to match the power output of your engine.

Awesome, a 6.4 crate engine is definitely a possibility. did you consider the SST "perfect fit" kit? I'm wondering how well it fits.

I am using the SST kit but it is designed for tranny to be in stock location. The Holley mounts move the engine about an inch farther forward so I had to lengthen the slots in the tranny crossmember to get the bolts in.

Thanks for the info, you have an awesome project. I imagine the 6.4 and the TKX trans combo should be a bad *** combo!
