01 transmission
 

one of my buddys has an 01 6 spd and when he shifts into 6th there is a faint grind what could be wrong with it?

has he been racin it..speed shiftin, sounds like a syncro

best thing he can do for the NV5600 is to change the oil about every 50k

no hes acually pretty easy on it just every once in a while he will run it hard but no speed shifting

i also agree, could be a syncro or heck even a bearing but i lean more towards the syncro. i say drain the tranny and see if you see any metal flakes in the fluid

Yep...sounds like a sycro to me as well. Drain it, inspect it and re-fill with fresh fluid!:U:

ok we will try that , thanks

Racing a 6speed :booo:
maybe he's not shifting into 6th right too,sometimes if a person times it just wrong it will kinda grind a little.

I've had Amsoil in my tranny for a while,still works good.
415k or so on it now.

Its also important to use the correct fluid.

Yeah,and the fluid that comes in the 5600 ain't cheap.

yeah like 2o bucks a quart:booo:
