For anyone looking for a tranny to rebuild, this is perfect for you. I have a 5AT transmission from a 2003 G35c for sale. The production date is 10/02. It shifts fine, but the tq converter has issues locking up and it jerks when too much tq is applied. For anyone that's interested, $300 + shipping or local pickup takes it. I decided to buy a used one and build that instead since my car is going to be in the shop all winter anyways. Let me know. Thanks.
