Re: Does your NP435 make whirng noises?

They are noisy trannys.
I have rebuilt mine 3 times (due to cracking the cases), and everytime I rebuild it, it sounds a little different, but it allways chatters and/or growls, and does a little shifter shimmy. The first rebuild and my most recent rebuild were completed by experienced tranny guys who shimmed the tranny properly and checked it out. Both guys said the noise was pretty much inheirant in the NP435 and to not worry about it.
I have run mine often in the 4000 + rpm, 75 to 80 mph range, on long trips, with no problems,...other than the noise.
