I have 171000 on my 03 2500 4x4 tranny grinds from 6th to 5th gear not bad but starting to happen alot. If I shift down slow will not do it. I pull trailers alot and have never had tranny hot or cluth.

 

Bad news - probablly take a tear down to repiar.
Good news - Can probablly drive very long time without repair if can stand scrape on downshift.

 

is that a nv 5600? if so, it sounds like the syncro's are going....i had mine repaired for the same symptoms for 1900 dollars back in '02

 

Regardless of who repairs it, be aware this trans has been out of production for a while now and most replacement parts are junk. That, and the fact that no one seems to know what to do with them to rebuild them properly. I'm almost to the point of considering an auto conversion.

 

Do you think it might be in my clutch does not feel right seems slow to disengage. A

 

When the shop that was messing up my 5600 played around with the clutch hydraulics... apparently did not know what they were doing there either.... when the hydraulics get weak, the clutch will tend to engage, not disengage. Very strange feeling sitting at a light and it starts to creep forward when the clutch pedal is on the floor!

 

Fixed Tranny injector rail leaking fuel running down front of bellhousing got big enough to start leaking under truck fixed leak just tightend nut.Took about 200 miles to start shifting right. Dodged a bullet there. But thanks for the help & input.
