Thank you Brian and Maria for this new video, as always full of all your great tips and the knowledge that you share! It tells a lot about the quality work that you do when you consider so many small details. Always looking forward to more!
Brian... Since more than a year ago I filled my T90 transmission and transfer case with the heavy duty oil I bought from you it shifts perfectly. Thanks, Juan
Hi Brian, another great video! Thanks for taking time away from your busy day to share this information. You break it down in a logical progression for the average guy to understand.
I used to rebuild T90s for customers (Retired from Willys Overland Motors a decade ago). I had original Willys Overland tools to work with. Makes a difference for the ease of rebuilding. The factory dummy shaft for rebuilding the cluster gear comes right to the end of the cluster gear with the thrust washers on it. That set up allows the cluster gear to simply drop in to place with out much fuss. I also had customers bring their transmissions to me after they had attempted the rebuild themselves. They did everything right. The issue was the quality of the reproduction parts was terrible. Cluster gears that had the outside diameters of the gears themselves were too large. Countershafts that fell through the cases, etc. I was doing this type of work from 1997 to 2009 and from what you are saying the quality of parts from Omix is still crap. They were selling junk back then. Worn used parts were more reliable than their new parts.
Thx Brian & Maria, not yet back on our Cj5, but saved to my watch list favorites when time comes to get back on it. Only drove it 100 feet since I got in Nov 2019 but when I do open up the tanny will know now what to look for. Stay cool up there,,101 again here today, and kicking our butt's. Bear & Sammie, TX.
Hopefully soon you will be back on the Jeep, but I do know how other projects often get in the way of progress. Starting to cool down a bit here and we are enjoying the 80's for a few days now. Hope your A/C in the shop is working good.
Hello Brian I’m a tool maker by trade just asking here ;could you take a clean up cut in that case and make a hardened washer the correct thickness to bring it back to specks? Thank you for sharing your outstanding skills and knowledge you are one hell of a talented man 👍
What lube are you using? What is the fit between counter shaft and case bores or holes? How are you sealing front end of counter shaft in case bore or hole?
Very informative, thank you. Just finished rebuilding my D18 T-case and want to dive into my T90. Used Novak Conversions for parts. Any issues? I planned to use Novak for the T90 parts but now you have me thinking some more. I was disappointed when I received my D18 kit and found bearings made in Japan instead of USA made Timken. Recommendation?
Thanks for a very informative video Brian! I have removed the transmission case from my CJ2a due to a oil leak from the balancing shaft. Someone filled the hole where the shaft comes through the case with RTV to try and seal it up. I see in my original service manual there is a gasket that goes between the front of the case and the bellhousing. I could not source a gasket from the suppliers. Can I use a normal paper gasket?
You should use a gasket between the front bearing retainer and the case. some early transmissions had a full gasket but it isn't necessary. If you need one you can cut it from regular gasket paper. Be sure the shaft or the case is not worn out. Should be a very tight fit that lube can not get past.
no, it will still harm the yellow metals in that transmission as well. 80w-90 is designed for hypoid gears such as in a front or rear end. The extreme pressure additives needed for the hypoid wiping action is bad for transmissions.
Interesting how the counter shaft can't be shimmed like the T84... A thicker metal spacer, behind the thrust washer on the back, lapped to give proper spec seems like the right solution... I guess I'm missing something.
countershafts should never be shimmed. The T84 Mainshaft is shimmed NOT the cluster gear. The cluster gear needs to be in the exact factory location in the case in order to have the proper clearance between gears. Shimming it can cause lots of trouble.
Hi, Im looking to buy a rebuilt t-90 for my 1953 m38A1. Do you have anything available.Thanks Jay. Im using my wifes email. could drive to conn. to pick up if necessary.

Glad you enjoyed it!
Thanks Brian. I am thankful you take the time to document your approach to discovery and repair.
You’re knowledge sharing is so generous!
Thanks, always good to have you watching and sharing your comments.
Great information thank you. Got to write those numbers down. Going to make a binder to go with my manuals
Glad it was helpful!

Thanks for the long term update. I have been using this lube for over 25 years and all my Jeep vehicles still shift perfectly.

Great video. I watch them all!
Is there any machining process that can salvage an out-of-spec case?
Do you have similar case measurements for a T-84?
What lube are you using? What is the fit between counter shaft and case bores or holes? How are you sealing front end of counter shaft in case bore or hole?

Love your approach man!
Thanks for watching.
Great video and awesome information. How does one get in touch with you? Do you have a website?
I don't have a website but you can contact me directly at metalshaper@comcast.net
Fantastic knowledge as usual !!
Glad you think so!
Thank you again Brian
Always great information!
appreciate you watching and taking the time to comment
Looks like you're staying plenty busy! Taker easy.
Super busy around here , hope all is well in your world.

Is regular 80w90 good for t176?
no, it will still harm the yellow metals in that transmission as well. 80w-90 is designed for hypoid gears such as in a front or rear end. The extreme pressure additives needed for the hypoid wiping action is bad for transmissions.

Just purchased a cj2a would like to purchase your trans. lubes
Thanks Brian
You bet!
Like the way you do thanks 👍
Thank you too!
Thanks for the info.

Mane shaft dia.
Great hard to find material.
Hopefully it will help out some people that are rebuilding their own transmissions
