G 35 TRANSMISSION WHINE[please help]

[keeper95]

The transmission in my G35 has a whine as it goes through the gear changes.This is the automatic transmission.I bought this car wrecked ,but there was no damage to the transmission or drive train.This car has not been driven for two years,and had only 1600 miles on it when i bought it,but as i recall, when i bought the car it had a slight whine,it seems to be louder now since it has been sitting for so long.The whining is only through the gear changes ,then it's quiet.I wanted to ask if anybody might know what's causing this.I was wondering if it could be a stuck valve or maybe the pump,or could it be the line pressure.Unfortunately i don't have a warranty,because the car had a salvage title,so as you can see i need help.My email is [email protected] I would certainly appreciate anyone's help. Thanks,Ronnie

You might try having a transmission flush done...

Hows the fluid look and the condition...

Might post this in the G35 forum as well, if you havent already.

the fluid looks fine.

I recommend you have it thoroughly inspected by your local Infiniti dealer and then go from there. I'm not saying to pay to have it fixed there, just pay them 1 hour of diagnostic time to figure it out. It'll be worth your while. Any further questions, we're here!

A whine between shifts. Hmmm, as above, take it to a dealer and have them run a little diag on it. The old G20's had a high clutch whistle between shifts that sounded like the tires chirping. Whining normally indicates lack of lubrication, imbalance or improper flow of fluids. Where was the car wrecked? Although it might have seemed fine, drivetrains can transmit forces everywhere in all types of collisions. The whoe purspose of a transmission, driveshaft, rearend, axles and wheels is to deliever the power the engine makes to the ground (we all know this, not trying to anoy or insult people), so in a wreck, those forces will be fed throughout the car via this same system. Also, if its durring every shift, and not just certain shifts, it indicates different areas of the transmission. It wont be any of the gears, as they are specific. There are numerous bulletins pretaining to valve bodies on all different models of nissan and infiniti vehicle. It might be as simple as having the valve body replaced and reprogrammed, but dont take that as your first course of action. Have it thoroughly diagnosed by someone you trust. Thanks!

Hey Mark Thanks for the information.One of the reasons that i asked this question about the whine is that i was hoping maybe i could get an idea of what the problem might be.My reason for this is i'm about 140 miles from the nearest Infiniti dealer.Quess i should of thought of this before i bought the car, but it really never dawned on me at the time.Could a stuck valve body possibly be causing the problem.The transmission fluid looks good and it's full.So i know it's not a lack of fluid,but it may not be circulating as it should.Would the stuck valve body cause this.What are the other probable causes ,if you know.I really don't want to take it to the dealer for a couple reasons.I have no warranty ,so i'll have to pay for it anyway,and the dealer is so far away,it would be very inconvenient for me to take it there and then have to leave it, and their prices compared to someone else are outrageous.I thought maybe i could find a good shop close by.Tanks for your help.
