Need input from 6-spd track guys
1) Year of Car - 2006 MR
2) Estimated HP - 280 actual whp at 5500ft ASL in Denver (est 310whp at sea level)
3) Total Track Days on Tranny - 2
4) Tranny Oils Used - OEM, just switched to 1qt RL SP Heavy, approx 1.5qt MT-90
5) Total Miles on Tranny - 20k
The 2nd track day consisted of 4 solid 20 minute sessions in 97°F ambient temps.
No failure yet. IIRC at point of fluid change, the stock transmission fluid (with 20k miles) looked a little cloudy at best, but didn't seem to be saturated with metal particles. The drain oil was not filtered and drain plug is not magnetic, so it's impossible to guess the quantity of shavings or paticles.

I have a SCCA Touring 2 Lancer Evo that I run at a National Level, which means we have 40 minute straight races. Our cars get quite a bit more abuse than at HPDE due to the length of the races, usually after the 20 minute mark stuff starts to go crazy. I am pretty sure the transmission is out the door soon, had shifting issues at Pocono that I hadn't experienced before.
1) 2006
2) About 250whp, just a tune and exhaust.
3) 40+
4) Stock, I change it after every other race.
5) ~17,000
6) ~17,000
7) Soon, anticipating April of next year after the first race
8) Won't shift to 4th
9) 5 speed conversion and Setrab cooler.
10) Stock
I think the 6 speed failure is inevidable, but I think at a HPDE level most of the people should be OK, I would put on a Setrab cooler to be safe though, I think with that and frequent fluid changes you may be fine.

Tsurara, the # of track days (races) that you've gotten out of your 6-spd is crazy. What courses did you mostly run your car at? Are they fast tracks? What were your average speeds?
1) Year of Car - 2006
2) Estimated HP - 370/340 at time of failure (Mustang Dyno)
3) Total Track Days on Tranny - 3
4) Tranny Oils Used - Stock
5) Total Miles on Tranny - 8200
For the people who've experienced failures, please provide the following information:
6) Tranny Miles at Failure - 8200
7) Failure Date (Month/Year) - 9/2007
8) Type of Failure - 3-4 Shift Fork (possibly more)
9) Solution (rebuild, 5-spd conversion, tranny cooler) - New 6 speed
10) Oil Used during failure - Stock
Now with Redline Shockproof Lightweight and Exedy Twin HD (stock clutch before)
Looking into doing a tranny cooler

I plan to change tranny/diff fluids at 10k intervals since the car doesn't get all that much daily use.
