A999 as a street/strip trans.

I had a 998 built up with a performance TC and stayed with the lock up. Set up to shift at 5200. The unit you may have is hydraulic only operated lock up no electronics or solenoids involved. It locks up at about 40-45mph and works good,lowering rpms and has a real 1:1 feel to it like a 4spd. I would not eliminate it on your 999 which is
a heavier duty unit than the 998. I have to add 98mph is not doing well with the combo you have.

Sounds like you have built what i need to build.
She has been letting the trans shift itself (4k rpm or so) but with transmissions age, and her weak tiny "girl feet" I can hear it shift A LOT earlier than that at times.
Thought a later trans with PTKD would eliminate this, and I would like to change the governor weight to get it to shift at 5K or so as you did.
And I agree it's not "doing well" the 60' sucks ( cooper street tires) and the early shifting is killing it. And her lack of experience. But she is having a ball so far!!
I optimistically think it can be in the 12's...

Where did your converter come from??
