Sticky: 370Z Transmission Failures (6MT)

DIGItonium

Hehe who knows about the extra power involved. It tops off at 380 ft-lbs right now. For daily driving it doesn't see much more than 2 PSI during the week. I'm pretty sure if my engine is taking a fair bit of abuse then my engine would have popped by now (knock on wood).

The original had to do with an issue with the aftermarket disk having too much marcel. It felt like the disk was constantly rubbing on the flywheel making it difficult to shift. Of course none of us realized that until the first day at the drag strip that I barely got out of the hole in 1st when things got worse. We pretty much attribute it to overheating from the 1hr wait in line with the stop and go traffic. Several times I had issues getting in gear.

The first replacement was fine, but I barely had it for a month when I had issues getting in 5th. It wasn't notchy. Half the time it took more effort going in, but never grinded. It got worse the next couple months which is when my tech tested it and decided on the replacement.

He doesn't think it was built quite right.

Just because I'm running turbos doesn't mean I abuse this car. It is my only vehicle and it is a daily driver. I pretty much baby this car. There are others running boost and drive it like it's stolen with no problems whereas I'm driving it to work on the freeway everyday. The only time I took it to the strip was when the clutch failed, and it has been 8 years. The 350z only been to the strip once.

[EDIT] Got word about my 3 month old transmission. Hopefully I can get a hold of it for synchro upgrades.
