Cold weather transmission noise
I have a 2004 Rubicon with the NV3550, with about 77k miles on it. We have had in the past month or two a lot of rather cold weather, and it appears if it's below 20 or so, for about 5 mins I have an intermittent whistling sound coming from the transmission. It use to start around 1800 RPM's in 2nd and 3rd gear. Then it stops after 5 mins. Then is fine for the rest of the trip. If it sits too long I have a little noise on the way home.
Is this just transmission fluid that may be low/old and needs to be changed? I am overdue, so it will be changed. It just seems like something is warming up then sounds fine.
