Well it finally happened. I haven’t torn into it yet but was wondering if these New Venture 4500 Transmission Repair, NV4500 guys were still the way to go? There are companies on eBay and amazon that offer the same style fix for half the price, anybody had good results with the cheaper option?

Maybe you can fix it yourself? Pull the back off the trans while it’s in the truck. I replaced my 5th gear nut in the truck.

That said I had a competent driveline shop just rebuild it and replace what’s necessary.

It seems to be the way to go for 4WDs. Can't speak specifically to brands. Had to do mine last year (2WD, so that wasn't an option for me) and in my reading around, people w/4WDs who used that retainer style had very good (and permanent) luck.

I wanna say it was a kit like this.



It’s been 6 years or so since I did it. I don’t own the truck anymore though.

That’s the same style collar. Did y’all use the special gear nut wrench or something else?

I think you could probably just tap it tight with a screwdriver and a hammer. I think with that collar it is not necessary to have it torqued down (at least, not to some huge value. IIRC it's supposed to be at 315 ft/lbs with the standard lock washer setup). It literally cannot back off with that collar on though, so it just has to not be loose.

Yes, it’s somewhere around 300 ft pounds. I have a few different full float hub nut sockets that might fit. I’ll tear into it and see what I need before I order any parts. Truck is at work and I’ve debated just doing the job there since it’s on concrete.

All those things are band-aids. Some last longer than others, but it is dependent on how much the gear and shaft is worn, not the design or price. The only true fix is a fully splined shaft with a new gear.

I spoke with standard and they offer the fully splines shaft and updated nut. Their prices are on par with everyone else and they are local.

I never had a 5th gear problem with any of the Standard Transmission & Gear fully splined shafts I had installed.

This trans has supposedly already had a fix, but idk what the last fix included.

I went with All State for my rebuild kit. Fully splined main and the works. I’ll actually be doing the overhaul in the next few weeks. But it was the most cost effective rebuild kit I could find online with the fully splined main and new 5th gear.

The nut has a small torx screw that came loose. It had lock tight but didn’t hold. Gear, nut and shaft all look good. I guess when I put this nut on, I need to leave the torx screw loose enough for the gear to go on, tighten to 300 ft pounds and then tighten the torx screw down? I’m gonna get that collar for it and shouldn’t have any more problems.

I got it all back together, used loctite on the nut and torx screw. I used the retainer and it all went together fairly well. Time will tell how long it lasts

More often then not tack welding the nut on just creates a weak spot and the shaft shears. There is only one good fix that I have heard of that lasts, already recommended.

364,000 miles on truck, spot welded nut on about 150,000 miles ago! No problems.

I guess you don't know what "more often than not" means. It appears you must be one of the nots.
