TRE Transmissions.
well that is actually good enough as the problem gear for us are the upper 3. and i don't mind keeping the 6th gear since no one gets to use that gear on most tracks. i guess the question is how much will these gears and a rebuild from shep cost. I just hope its reasonable.

Call Shep Trans and see what they have to say about the 6 Speed Now 
3rd ,4th and 5th gear upgrade

Next to the stock weak 4th gear that the 6 sp loves to eat.

+1 for pricing on the shep 6 speed upgrade total cost.
Really? ...the base of the gears are twice as thick...with more surface area to boot. Though Its gonna depend on what power you are looking to push through it.

I'm Probably a little late on this, but I spoke with John@TRE and Trevor@Sheptrans, and both were very excited about the service they offer for the 6-speeds, but willingly admitted that these transmissions will not hold anywhere near the power the 5-speeds will.
I had planned on throwing the 6-speed on my car and trying to pump 700awhp through it, but after careful though, I decided it would be risky, not cost effective, and I'm sure Emery@STM wouldn't want to clean up the mess after if blew up on his dyno

I'll make one to continue on the discussion. Since this really has gone off of the TRE topic, here is a new thread https://www.evolutionm.net/forums/ev...ml#post8083681 on discussing all possible options of upgrading the 6 speed.
