Engine/Transmission (1994 - 1998) Lost 5th NV4500

[davidb]

I have a 98 2500, 4x4, TST #11, GSK, 13" South Bend Clutch and I lost 5th gear this morning driving on a flat section of highway, not towing, doing about 70mph. No bang, pop, skip or anything. I'm assuming it's the nut backing off on the main shaft. I'd really appreciate some insite here. Can I access the nut from the back of the transmission after removing the transfer case but without dropping the transmission? Is there an upgraded nut available? Any help here is greatly appreciated!



Thanks,

David

It is on the rear of trans case. On 2wds, we remove the tail housing for access. There is a new upgraded nut, but on mine I just cleaned things with brake cleaner and reinstalled, banging the nut real tight. Has worked for 80k or so.

Yes, you can get to it without pulling the transmission. I would use the new Dodge nut, and use 680 locktite to mount the gear. That is how I did my '97 and it held for 200,000 + miles. This should also help

If you want to know what it looks like in there see pictures of my 5th gear fix at the top of this page: http://picasaweb.google.com/mark9474/TruckStuff. I didn't run mine real long before switching to the 6 speed but it sure was a pain to remove when I tore the transmission down later.

you can also get a new / improved nut from Quad 4x4. quad4x4.com
good stuff. . If the spline isn't damaged, go ahead and replace the old nut with the new/improved one... good luck.

Yeah mine just backed off, gear was ok, new nut from Dodge and lots of loctite. Still holding strong...
