thanks for replying. I see what you're saying, I just don't quite see how that would make it hard to shift .................

Picture this: The synchro assy uses friction to match the speed of different gears. If the transmission shafts are difficult to turn then the synchro assy has to work harder. When you step on your clutch pedal, you are releasing the disc and input from the clutch/flywheel so that the input shaft can spin freely and the sunchro can match speeds with the gear you are shifting to.

Ahhhhhh , I gotcha now. Okay so an unseated, preloaded bearing cannn be an issue.

Anther person had a hard shifting problem because of supposedly not having a gasket between the transmission and adapter housing which supposedly caused binding because the mainshaft was bottoming out in the input shaft of the transfer case , pushing in on the mainshaft making it harder to turn. He ended up using 2 gaskets.

All I used between the tranny and adapter housing was anerobic sealant. They sell paper gaskets. I believe the sealant would do a better job sealing.

Damn , so I gotta make sure all bearings and thrustwashers are properly installed, the synch. assemblies, and blocking rings are made right, correct snap rings are in correct place, and I guess see if the mainshaft is bottoming out in the input shaft.

We've had a few warmer days here and after getting off the highway on my way to work the jeep is all warmed up and it shifts into 2nd fine. 2nd and 3rd gear still seems a little unsynchronized some times and it's making me wonder if the blocking rings are a little defective but for the most part it's shifting fine at these warmer temperatures.

Yes , why do you ask ? also I wonder what is helping it shift better the expansion of the parts or the thinning out of the lube ?

I was wondering whether you went back to the synthetic lube, that's all.

Yep gl4. Do you think it would be okay to try 50w motor oil or some REDLINE MTL , i've heard about ?

I've always wondered about Redline MTL. Try it and see if it makes a difference.

I have sta-lube(crc) 85w90 gl4 in my tranny now and it shifts better when hot and therefore thinner at about 85 weight .So it seems to be the oil warming up and getting thinner that is making it shift better. So the fluid I ordered will be thinner cold than my 85w-90 is hot.
Here is the fluid I ordered. The redline I ordered is a gl4 75w-80 so it will already be 80(thin) even when still cold. The reason I got 75w-80 is because even when my 85w-90 is warm it's still a little-notchy I guess

drained and refilled my tranny with the REDLINE MTL. It feels a little better- a little less clunky but it still feels like things aren't quite synchronized and are notchy...........Can I live with it ? -don't know. If I pull the tranny and it turns out my bearings are seated then I would replace the synchros and maybe the 1st/2nd synchronizer assembly but I would just be replacing them with crown or omix ada ,which is what is already in there so...............

UPDATE: I went on a test drive this morning. It was about 40 degrees. It wasn't as hard to shift but still not nice. Want to do another test drive when it's even colder......

UPDATE: my expert brothet in law says its shifting normal-to good. Hes good. But it still feels a little clunky and like its not quite lining up in there. And his reply to that was that it feels more "trucky"(more heavy duty) to him. When he had a t18 it would kinda go into gear like that. I don't know though
