Default new Tremec TKX 5speed is out! 8000rpm shifts rated at 600 ft/lbs

For those of you unhappy with your TKO600 here is the newest offering from Tremec..... the TKX 5speed!
https://www.hotrod.com/articles/trem...ssion-install/

Higher RPM shifting and smoother shifting

I'm sure the torque rating is very conservative.... as the T56 Magnum is rated at 700 ft/lbs .... and plenty of us are pushing 1000rwtq thru them without issues.

Has anyone driven the TKX yet? How does it compare to a T56 Magnum (Fstyle)?

I've got my TKX in the car since summer last year but the build isn't done so I haven't driven it yet. No mod to the trans tunnel was required. I am coming from a T-5Z with a small block ford making 350hp. The car now has an LS7 making over 500whp. Should be fun

I have installed two.

One replaced a TKO and the customer was ecstatic. Shifts are so much cleaner.

The other replaced a Richmond 5 speed and that was also significantly nicer to drive.

Shift throws seemed long to me but both cars had relatively tall shifters and I am comparing to the 6" stick on my T56. I didn't get to really wail on either car so I can not comment on high rpm shifting.

I just sold a customer a close ratio TKX with the .81 5th gear. Hopefully he will be driving it this month and give us some feedback. LS swapped 70's C10 truck
