Re: Noisy NV4500
I doubt that driveline angles would cause tranny noise. 5th gear had an issue with the nut backing off, but it might have been particular to the Dodge versions. The way you describe it as " high pitched whine and metallic" are indicative of the bearing going south. A few years ago I had the exact same noises from my Nissan's 5 speed. 4th gear was silent, shift into OD and it got ugly. I took it to Ramco and they rebuilt it. Sure enough, bearings related to the shaft with OD were shot. If one bearing is bad, replace them all. The synthetic oil for the 4500 is CRITICAL!...and expensive!
