[Gwhut?]

Hello all! im in the soon to be proud once this is dealt with owner of a 05 G35 coupe.

I purchased the darn thing with a check engine light its the valve body. i got a replacement transmission asked for 05 got a 04, sure no problem NO! big problem i did not know of this 2004 2004.5 valve body change. now this trans has no vin number on it, yard i got it from refuses to find the car and give the vin.

ive been looking into ways to see if i can find out if i can use it or not but i come up with nothing any suggestions? best info ive found was on a ebay post.

judging by this they are selling the 03-04 valve body that has the tcu and the one im looking for is the 2nd one?

Seems unlikely you'd need to change out the entire valve body especially since the inside of your trans looks pretty clean, my guess is if there's an issue that it's a solenoid and the actual valve body is fine?

Thank you for the response elwesso that picture is of the replacement transmission I purchased have yet to open the one in the car I believe the code it gave is a p1757 or 1759 both of which or solenoid problems says this chart. When I first start to drive the car it runs fine for a few minutes then it'll bang or what ever it does when it goes into limp mode but after bout 20-25 mph it goes into 3rd gear and feels fine.

I don't have a lot of experience with the G35 transmission in particular, however most the time in Nissan transmissions the electronics inside are pretty reliable.. Probably about 8/10 times whenever there's a trans issue, the trans is junk and the whole thing needs replaced. Occasionally you can get lucky. I would just hate to see you go through the effort of all this just to find out there's something else that's messed up inside.

I know if you get a rebuilt trans from nissan, they put a brand new valve body in there, and last time I checked if you get them through one of our fine retailers like Infiniti of Scottsdale (www.infinitipartsusa.com) they're pretty reasonably priced compared to a local rebuild (which in mine and many others experiences hasn't ended well).

Another good place to check into is Level Ten or Import Performance Transmission, both in New Jersey. I had a Level 10 in my Q45 and it was a nice unit, survived a lot of abuse for a lot of miles.
