nv4500 still shifts hard

My new tranny is still hard to shift. It's hard to shift even with the jeep off and the clutch in. I bled the clutch again and adjusted the linkage until the clutch has to be about 1/2 way out before it engages and it is still hard. If I have it running and put it in 4th first, then the other gears start to go in easier. But, if I let the clutch out in N again, push it in, and go for 1st or 2nd, it doesn't want to go. Anybody got any ideas?

Re: nv4500 still shifts hard

I don't recall, was this a brand new assembly? Sounds like maybe the shifter assembly is tight (fresh) or binding (used). Or more likely the synchros are not working well. Have you tried driving and shifting without the clutch. If you have never done it before, you might want to find someone who drives truck and have them try it. My guess would be that the synchros/shift collars are not sliding together smoothly for some reason.

If the tranny is brand new, a little rpm shifting without the clutch usually smooths things up pretty quick.

Re: nv4500 still shifts hard

hehe, nice try extinctjeep. Yes, it is a brand new tranny. It does feel like it's in a bind. The base of the shifter makes a pop sound when it does go into a gear, but once it's in one it doesn't do it anymore if you take it in and out of gear. And it doesn't ever make any grinding noise or anything in the transmission, maybe it just needs some break in time?

Re: nv4500 still shifts hard

Hey, glad to hear that you finally got it in! I had that exact problem with mine for the first week or so. I had to readjust the clutch 2-3 times in the first month (keep in mind I have a mechanical linkage/clutch).

It would be real hard to get into 1st gear, a little less in second, and not at all in 3rd. I could put it into 3rd, and then go to 1st with no problems what so-ever.

Basically, I had to move the clutch adjuster out (like you would if the clutch were wearing) by 3-4 turns per adjustment. Not sure how you do that with a hydro clutch, but I'm sure there is an analogous adjustment.

Re: nv4500 still shifts hard

Thanks for the info bluseman. I can use some tips from those that have worked with this tranny before. I have been playing with it and driving it around a little, close to home, and it is starting to get better. I orderded my rear driveshaft Monday, so I'll soon be able to put it back into 2 wheel and see how it drives then. Between the tranny, lift, and being in 4 hi front wheel drive, it's hard to tell what's working right and what's not. It's getting close though![img]/wwwthreads_images/icons/smile.gif[/img]

Re: nv4500 still shifts hard

How strange. I did the bending on the shifter tonight and it shifts almost perfectly now. 5th is still stiff. I'm not sure, but I think the heat loosened some stuff up. It took a lot of bending to get back to the factory opening and not hit anywhere through all gears. It looks stock again, except for the 4x4 shifter which I still have some work to do on that linkage. I wish I had a good camera to do a write up on it all. The one I have has no flash, so the pictures are only good if it's REAL bright out. Just a little update.
