Hey guys, I've had this problem since I bought my truck, and have just gotten used to it in the way i drive, but it pops out of fifth. What I find wierd is that it only does it on deceleratation, or when going down a hill with no throttle. In my experience trannies usually pop out of gear on acceleration. I've read a bit about a locknut problem associated with 5th gear, could this be related to that, or maybe a chipped tooth/bad synchros? Thanks in advance!

 

Hi Tom, and welcome to the site; you'll find lots of good advice here, and most of it accurate! May I suggest that you fill in your signature line with what your truck is: make/model/year/tranny/etc, and include any mods that have been done to it. That way you'll get better (and more) responses.

 

Doh, I forgot that was my first post here, I'm been lurking and searching for a while, lots of good info here, just never got around to filling in my sig. Done now.

 

Is that the NV 4500 tranny? I guess it doesn't matter, but you might talk to Dan the Gear Man at Quad 4X4 in Roberts, Montana...I've never met anyone as knowledgeable.

 

Have to admit Quad 4x4 has a good explaination and seems to have a good fix for the 5th gear probs.

 

Sounds like the 5th gear synchronizer.

Heres an example...

Yep, sounds like the same problem. Stupid thing is, the synchros were done the week I bought the truck, unfortunately, I bought it in Ontario, and had to be home, so I didn't have time to ***** and whine about it. It would have taken them another 3 days to fix it, then I would have been late for my first day on a new job. Oh well, extended warranty will cover it, I'll just have to wait till spring when I can get my motorbike back on the road before I can give my truck up for a week! Thanks for the help guys.
