sub par is an understatement, mine doesn't even work. you have a very very good point.

But Loctite makes some too so it might actually be legit.

What about a bushing? Provided the transmission output is in any kind of serviceable shape I could see having a machine shop bore out the t-case and make you a bushing to fit the transmission. Not sure if it would be financially feasible, guess that would depend just how bad you don't want to tear down the transmission.

I cleaned up the splines. I wish that the input shaft was in worse shape than the output but sadly the truck gods were not helping me out.

not too bad to do in a shed if you have the pullers

Looking for opinions on this. I was already planning on selling my truck as its getting rusty, I don't have a need for a 3/4 ton diesel, and most importantly, its not practical to have all my vehicles stick and if I ever get in a situation where I need my girlfriend to grab my truck to pick me up on the side of a trail with a busted sled or dirtbike, she needs to be able to drive it (she can drive stick in an emergency but she's deaf so she just stares at the tach the whole time and doesn't watch the road). So I have some options here:

sell it as is in non driving condition
pay for a trans rebuild/replacement and do the transfer case myself....and then sell it for more as a driving truck
part it out

I just bought a house so I don't have a lot of time to go rebuilding the trans myself and I don't have the tools or experience for it. I'm going to lose money on this no matter what, what's the best option to lose the least?
This is a rust belt truck so keep that in mind. let me know any other options I might've missed.

What's left of those splines will do the job for a test drive.

I hate screwing people over but it crossed my mind for sure. in its current state, the remaining splines is not enough as the truck cannot move under its own power. MAYBE if I replaced just the transfer case input shaft it would be able to hold up for a test drive.

I didn't realize they were that stripped out. If the truck were not rusted out it would be worth it to sell it as a runner, but in this case I guess I would call the junkyard and they can bring a tow truck to carry it off. Hand them the title and move on in life.

Have a shop replace the shaft in the transmission (do syncros while it’s apart) and it sounds like you are able to tackle the transfer case rebuild yourself.

Idahotrans.com has been helping me source parts for my transfer case maybe they could help you out with shafts and such?


I’d fix it and drive it.

I'm having a hard time finding a place that's willing to even touch a manual trans, let alone the beast that is the ZF6. So far I've found one shop near me that didn't immediately say "we don't do manuals" and they're yet to get back to me on a quote.

I realize that he's not local to you, but when I still ran the auto repair shop in Seattle, I found a good man in this company. He told me that he "cut his teeth" on rebuilding rear axles, etc. If you don't decide that he is someone you want to work with, at least give him a call and have a conversation with him about it. He was very reliable in every transaction that I ever did with him and also I sent a lot of work his way that I didn't have to touch because I didn't want to have to stand in the middle if there was a problem Only one customer that I know of had an issue, but there were ten others that were happy with his work.
He's in the town of Kent, WA. about 1/2 hour south of Seattle, WA.

I just thought of one other option. If you look at the damage done on the splines, about 2/3rds are damaged and the last 1/3 is untouched. The input of the transfer case only protrudes an inch or so beyond the flange and that leaves a lot of unused spline. I can get a new input shaft for about $80. I'm no machinist, but would it be possible to friction weld an extension onto the shaft and recut the splines on it so it actually uses all of the available splines in the transmission? Sorry, I know its possible, would it be financially feasible as opposed to tearing down the whole trans? Or maybe get a custom one ordered from whatever companies still make them?

If I were in your shoes I would probably looking into those Loctite or AMS products. This kind of thing appears to be what they are designed for. If I could find the data to justify giving it a try then that's what I'd try. Then list it at a fair discounted price and if/when someone asks why be straight with them and tell them the what happened, what product you used and what spec/data there is supporting it as a viable repair.

Oh, and tell your girlfriend to stop watching the tach and feel what the motor is doing through the shifter. Heck I don't know for certain on these trucks in particular but every other manual I've ever driven you can usually feel it in the floor board when it's time to shift.
