LT95 Issues

My LT95 recently stuffed itself while going down the highway. Other than the fact that the thing screams like all 95's and Faireys, the only indication something is wrong with it is it won't stay in high range. It drives normal in low, but when shifted into high it clunks into and out of neutral loudly and forcefully (broke my shift knob).

Went into the transfer case this morning to rule out a quick repair with what replacement parts I have available. Some interesting gasket material on the transfer case and the overdrive. Seems to have held up great though.

All of the gears have a small bit of play to them at some point depending on whether its in high or low. Having never opened this kind of transmission before, I have no idea whats normal. Also beyond the copious amounts of metal shavings, no huge amount of visible damage and no sign of where that big chunk of metal came from.

Any experienced eyes out there that can help me out here?

Are the shavings magnetic? If not then they are probably from the layshaft shims. when they let go, you get a bunch of play, enough so that it can pop out of high.

Some of the shavings are magnetic. A lot of them are brass.

Sounds like the shims went. You'll need to check how much float there is. You can re-shim without removing the transmission (fiddly job) or if you're up to it find a tapper roller bearing kit ($$) and make it much stronger. Or replace it with a new or used unit. A few of us have a spare LT95 sitting in the garage.

I never took one of those apart but what I believe is the low range (small) gear on the intermediate shaft looks like it might be discolored as if from heat. Or it could just be covered in oil. I would check that out. You could always just rig up a big rubber band and save for an LT85 setup.

If one were to swap gearboxes from an LT95, to something else, why an 85? the late spec R380s were stronger, right?

Yeah, I'd probably detonate the LT85 behind the 6.5. The R380 is probably stronger than the 85, but the 95 is said to be stronger than both.

The gear is certainly discolored. Looks to be baked on oil from... overheating?. Otherwise it looks like it didn't sustain any damage. That is the low range gear though, so unsure why it would have gotten so hot.

I always thought the LT85 was the strongest 5 speed

So thanks to everyone that sent me manuals and words of encouragement. Took it apart a couple weeks ago and ordered up some repair parts from John Craddock. About 500 bucks later they arrived (yesterday) and I rebuilt the transmission this afternoon. Went pretty quick and was done in a few hours, to include having to fabricate two tools to get the intermediate shaft out (it was really welded in there from the melted bearings). Turns out the thrust bearings were gone, hence the bronze bits, and two of the three needle bearings were completely without their plastic bearing races. Why are they made of plastic? Pretty crazy... All new gears, bearings, washers, seals and shafts in the transfer case. Not bad!

Anywho, the gear box is back up and running!
