Verdict on current TKO 600 Transmission?

Anthony,

You are correct,I did have a problem with a tremec. The rectangle detents in the syncro assembly were cracking. This would cause the tranny to hang up on down shifts. The upshifting was always fine. The new detents were free from tremec and the tranny worked well after that.

I was downshifting into second or third at 5500 rpm into the lower gear and I was not to gentle at it. I don't think the tranny was designed to be downshifted at that high of an rpm into the next gear but with a red line of 8,000 rpm, 5500 or better was normal.

I decided to buy a jerrico after the downshift issues. Before I baught the jerrico, I was running at willow springs when I went over the hill (turn 6) in third gear, as I pushed in the clutch for a gear change, a giant boom sounded and it was coming from the tranny. I coasted to the pits and onto the trailor it went.

I allredy orderd a jerrico but I thought I had broken third gear for sure in the tremec. When I pulled the tranny, the motorsport clutch had exploded. The tremec was pulled apart and inspected. It was in perfect shape. I was road racing with slicks, a 675 hp, 525 ft pounds of torque motor with a 3.89 gear. I drove the tremec hard and never blew up third gear. The light weight of the car saved me, I think.

For the street, the tremec works great, for all out abuse, get a jerrico.
