Can't find a transmission
 

I have a 04 G35 coupe early build. need a new transmission, but can't find one anywhere. Does anyone have any suggestions where I can get a rebuilt/remanufactured with a warranty, or suggestions on anyone who rebuilds these?

Car-part.com should bring up a few options in your area.

Tried that already
 

Thanks, but i've tried that alreay. All used over 150k miles. No warranty. I've already replaced this transmission once with higher milage Tranny and it didn't work out so well. I'd like something that's going to last a bit.
