Willys MB T84 Transmission Destroyed By Using The Wrong Lube

[@Phxphenom]

I want to buy an early sixties Willys truck and have Brian restore it. I have worked on a lot of little British cars and have a deep appreciation into what goes into restoration work. Brian is the only guy I would trust after watching his videos.

[@RFJP_G503]

Nice job explaining how to shim a T84… It’s a mystery to most 👍

[@metalshaperJeep]

Thanks for watching.

[@ginacoronel6872]

It's really great to see you are back!! Thank you for the great info and tips! Does the shimming on the main shaft apply to a T90 as well? Really sad to see a transmission be messed up from using the wrong oil. Hope you are doing well!

[@metalshaperJeep]

T90's don't need shims. By the time that transmission came out production was very accurate and the shims were no longer needed to properly put a transmission together.

[@juanzayas7719]

Brian... You convinced me a long time ago that you sell the best lubricants for the Willy Jeep T90/T18 combo. That's why a bought two gallons for my Willy and had it shipped to Puerto Rico. Juan

[@metalshaperJeep]

Thanks Juan, your transmission and transfer case will be safe for a lifetime. Thanks for watching.

[@jimhoran5445]

I’m glad you put out a video! I was ready to call out a search party for you! Lol

[@metalshaperJeep]

Hello Jim, my video views are way down and I am so busy I just didn't have it in me to make a video. Felt this information needed to be out there so I did some filming. I have lots of interesting projects in the shop but most youtube viewers have no interest. Trying to come up with some new content before I come back full time with videos.

[@aussiedazvk4djh889]

G'day Brian. wow that was an expensive exercise. 👍

[@metalshaperJeep]

You know the saying..... you can lead a horse to water but you can't make him drink!!!!

[@randallstewart8487]

Good to see you back Brian,missed you,good tips on the T-84,I will be buying some lube for my T-90 and D-18 transfer case within the next month or so,trans is already together,have to order a few parts for my transfer case and they will be ready to install and running your lubricant! Thanks Brian!

[@duckhunt1058]

I have watched countless videos and read countless threads including the TM section on the T84. I spent many hours working on it. I did get a NOS case as I wanted to start fresh. That included some NOS parts and some repro. I did use an old T case but didn't cut it. It helped a lot. One thing I remember is use all the gaskets needed for it as they play a part in the shimming of the transmission. I did a lot taking it apart and putting it back together. Some said the blocking rings had to be rather tight no slop and another where the gentlemen said slop is good in that area. I had that. Fast forward to today. I'm driving it and used GL1 at the moment and so far no popping out of second and no fluid loss either. I do check them quite often. I do maintain the oil change at around 500 miles just because why not. Won't hurt it. As another gentlemen here said the manual changed from GL1 to GL4. I'm curious as to what really happened to the transmission in this video. I've never seen that happen in any vehicle I have worked on. My first thought it low oil for that kind of metal failure. Just my opinion. Brian you have a different assembly process than what I have seen. I have saved for future reference. I like to see how others do it. One I did see is use an old bearing and open it up enough to take it on and off easier than a new bearing, I did that and I'll tell ya that saved me a lot of time. Again many ways people put them together.

[@ericfgs]

Installed your lube in my T18 last week. Drove it today. Great stuff. Clean smooth shifts. Highly recommended. Thanks Brian

[@RADIOACTIVEMASCULINITY]

I miss your videos!!!!!!! Did you repair that frame? I was really curious to see how you do frame repairs

[@metalshaperJeep]

Working on the MB frame now.

[@rob.gernert_FORD-GPW-94445]

Fantastic information. One more question .... which way does the "Wavy Washer" go on the shifter plate? Above or below the plate on the pin? TY

[@metalshaperJeep]

above the plate

[@lencost1]

Thank you for another valuable lessen!

[@johndoe43]

We have confusion. I thought gl5 was for rear ends and gl4 was for trans and t case. That's what the book says. Gl5 being high in phosphorus for the ring and pinion which you don't want on the brass or copper. For 30 yrs I ran gl5 in my trans and when I would change the fluid there would be a lot of brass in the fluid

[@pietervanderwalt2388]

Thanks for the video Brian!!

[@rowycoracing]

Good stuff thanks!

[@metalshaperJeep]

appreciate you watching, thank you

[@LetsBuildaWillysJeep]

Great video! Very helpful 👍

[@conceptalfa]

👍👍👍!

[@scubasteve7946]

I am sure that reverse idler bushing is bad also. Thanks for the education 👍👍

[@metalshaperJeep]

Yes it was and was replaced.

[@thomassawyer9478]

Amazing! What type of transmission would be ok with that GL4 lube? Something more modern?

[@metalshaperJeep]

GL4 is a rear end lube. Early transmissions need the proper viscosity and a safe for yellow metals formulation. Brass and bronze are extremely sensitive to extreme pressure additives.

[@joe3973]

What is the list of reasons the T-84 jumps out of second gear ?

[@bearsrodshop7067]

Like other's, great to have you back shooting some more great tips. Hey, mama Bear sees you are stating a mustache ??? Says it look's good,on you :)>,,,,,Best to Maria from Bear & Sammie.

[@wfravel18]

I will be buying

[@metalshaperJeep]

everything in stock and ready for shipping

[@storetapir]

Oh dear, that looks like one of those supposedly “NOS WOF” transmission cases sold by that parts guy in Texas. There is some suspicion in the community, that they are in fact old French made repros, as they are missing some of the casting info normally on WOF parts. Some had huge problems with these cases, myself included. Some of the bores for the shafts were drilled too close together in the case, making everything bind up when assembled. Took a while to figure that out…

[@duckhunt1058]

I bought one from him and so far no issues. Not hard to assemble the transmission either. It did have a fair amount of cosmoline on it.

[@wlogue]

Thanks Brian! It's been awhile, hows the v6? We had little old Madeline the 3b out in the neighborhood bushes today, pretty fun! Cheers bud!

[@metalshaperJeep]

The V6 is just about finished, just have to install distributor and plug wires. Have a 465 on the bench right now ready for rebuild that is going behind it. Hopefully it will be in the test stand and running very soon. Glad to hear you had your 3B out, always good to exercise them from time to time.

[@georgemace3102]

It’s such a shame that people will not take your professional advice and save themselves a lot of grief and money.

[@aafitter007]

Hi do you fit a gasket gearbox to transfer box yes or no ? Thanks colin

[@metalshaperJeep]

yes, gasket goes between transmission and transfer case

[@pietervanderwalt2388]

Hi Brian, I stay in South Africa. Will you be able to ship lube this way? I know the shipping won't be for free. Also not sure if UPS or Fedex will ship lube overseas?

[@bryanbdpp2895]

It was my transmission. I already had lube or I would have gotten it from Brian. It is looking like the oil I received was NOT what it was supposed to be. Waiting for further analysis and explanation from oil company...

[@lawrencemathews6182]

What and where do you ream before the main gear goes in?

[@metalshaperJeep]

There are two bushings in the cluster gear. when they are installed into the gear they get smaller and must be reamed to size so the countershaft will fit thru and have the proper clearance for lubricant around it. If the bushing are not reamed to size first the bushings will seize on the shaft and cause trouble.

[@lawrencemathews6182]

@@metalshaperJeep got it. Thank you.

[@spymaine89]

explain please how could a bad lube. cause damage, you make a lube? what about the ww2 lubes ?

[@metalshaperJeep]

extreme pressure additives in the wrong lube will eat away brass and bronze. This is a fact that people don't understand. My lubricants are yellow metal safe and I have been using and selling them for over 30 years with no problems. Do not use any type of lube with extreme pressure additives in an early transmission or transfer case.
