Transmission????

Scott
Get on YouTube and search for “Rick Stivers T-90 Teardown” video, it will walk you through step by step tear down and rebuild of your tranny.
He also has the teardown and rebuild of your transfer case, you may as well go through it while you have them both on the bench!!!

You aren't annoying anyone Scott. This is what the forum is for, and this is how we get the information! There is a lot of support captured here over many years. Be sure to search the tech sections for subjects that have been encountered before.

When you look at Rick's guide, be sure to make this correction. https://willysjeepforum.kaiserwillys...-Stivers-Guide

It is important to note, the Willys Universal Manual does a great job of walking you right through the transmission. I would highly recommend following it after watching Rick's video.

At this point I think you have done as thorough an investigation as you can over the internet! If we have communicated what is going on back and forth correctly, I would say the reverse idler area is at fault. I am anxious to see what is going on in there.

It is strange - and I've noticed it over several years now - topics seem to run in cycles.

We go deeply into the innards of engines; cooling, oiling, valves, and a lot of carburetors. Then we go off on electrical topics; generators/alternators, regulators, gauges. But - this last month we have been in gear school with the lessons on how to set up a differential and your questions about the innards of the transmission.

Then there are the metal magicians who are in a whole different world of their own .....

You think we'd know a little by now - but we're all still learning.

So a quick question. Doing parts inspection and making a shopping list. The reverse idler gear that the supplier list says 15 tooth count. The one in my transmission is a 16 tooth count. Would this make a difference?
My reverse gear is a 29 tooth count, which is what they list in catalog for replacement.

Up until the mid to late 60's T90's had 16 teeth. For some reason the tooth count was phased in to 15 in the late 60's. You will find both 16 and 15 in T90's from the mid 60's and later. The gears are interchangeable.

Ok. So your saying I should be good with a 15 tooth gear.
Thanks for that info.
