4l65E WOT overdrive shift, DEAD! OK, here's what I got...
2006 GTO
P1SC @ 8psi w/ meth
Kooks 1 7/8" catless w/ 3" header back exhaust
Ford 8.8" rear (IRS), Trutrac, 4.56 gear
Weld 15"X10" 7.5" BS rear with a 275/50/15 MT DR, skinnies on front
3840lbs with driver
no idea on HP/TQ
car has 22k miles
After i got the 8.8 installed, it lasted about 3k miles. I figgured this was going to happen. It hit the rev limiter while shifting into overdrive @ 110mph. I immediately backed off, thinking, Thar she blows! I stopped, checked the fluid, no burnt smell or discoloration that I could tell. I got back home, pulled her in the shop, changed the fluid, and it looked a *little* dark, not strange smelling or anything. I did continue to drive the car about 200 more miles last week, the slipping got worse. It then began to slip in 3rd, so It's parked now.
My question- Will one of the sponsors be able to build a 4l65e trans to hold up in my application? Last summer before the headers and the gear swap I made about 8 passes at the local 1/8th mile. I guess I'll average about 10 to 15 passes next year. I don't drive the pi$$ out of it, not all of the time. I have another DD now and will expect to only put about 6k mi. a year on it.
Thanks for your help/ suggestions.

I guess you have your reasons to run that deep of a ratio, but it put you into OD at 110 MPH according to your story. I have had it hammered into my head to never shift into OD @ WOT.
Running a 9" in mine with Detroit Locker and 3.70 gears. Even with the juice I will still be in 3rd gear going thru the traps at 135 plus MPH. These 4L60E/4L65E trannies will EAT the 3-4 clutch packs at WOT.

I would be happy to discuss this build with you. Apparently what you have experienced is failure of the 3/4 clutch pack. It is possible that the band burned, but more than likely the clutches are gone. It is not at all abnormal in a stock application to see that happen.
Give me a call and I'll help you make your decision.

Those gears are low but a well built 60 or 65e should be able to handle what your doing . And any of the sponsors here including us should be able to handle the task. Give me a call if you would like to ask questions or 
of you have yahoo messenger.
Thanks
Thanks

I'm using EFILIVE and I have tuned the TCM for WOT OD. I'm running this gear because most of the local tracks are 1/8th mi. And, I just love the pull on the bottom.
I work offshore in Nigeria, I won't be back in Mississippi until December 20th. I just want to minimize my downtime. I'll be sending you guys a PM, Thanks ACE and Performabuilt.
