2 Nismos transmission failure after highway driving.

Baddriver

Ok, we were in a fun run along with 5 other mostly automatic 370s, 4 more GTRs, a wrx and an old lancer (non-evo), and a bunch of euro exotics going at an average of 140- mph. when it's time to pay at the toll gates...

Only the 2 nismos won't go forward. Exact same symptons. Heavy vibrations and loud clunking noise when we try to go forward (or back). No, smell of burnt clutch tho and last symptom, can't be pushed on neutral.

We had to wait 30-40 minutes or more before we can drive it forward again and had to wait a bit longer to let the car cool down.

Anyone else experienced this? Manual/Nismo owners? This is highway driving so shifting is minimal.... only heavy foot. yeah, I did linger on 5th gear a few times but most of the time, I was on 6th.

additional notes:
1. The other Nismo has an HKS oil cooler so engine temp isn't an issue.
2. yes, I did go on limp mode hehe.... my car limited to 5k for a while but I already let the engine temp revert to 2230ish before we stopped.
3. My friend's Nismo, had the tranny fluid change, then drove the car at 140+ mph again and the same thing happened. mine is still sitting in my garage.
4. cars seem to be fine when driven slowly for now.
5. My evo 9 with intake/exhaust/tune mods never gave me a single problem!!!!!

hehe... any info on other mt users would help!
