In an earlier life in the 1970s I made a living rebuilding these gearboxes, among other things. Looks like you need a set of syncro rings, three dogs, a spring, a set of mainshaft bearings, and a counter shaft. The countergear has rollers that get packed into it and held in with grease. Those rollers eventually erode the layshaft or countershaft. If you can't source a good replacement I've resorted to reinstalling the shaft turned 180°, as the wear occurs on the top surface of the shaft, as load forces the layshaft and mainshaft apart. Be sure the countergear bearing surface is ok though. You also need to replace that worn shift fork, and get a set of seals and bearings. Not that big a deal to rebuild these things. Have fun!
Thank you Erik!! I will be pining your comment for others to see since it's a lot of great information! I was hoping I could flip the counter shaft and reuse most of the parts. I am going to TRY to rebuild this transmission. Probably not in the near future as I have more pressing matter's to attend to. I have a lead on a good used trans that I can chuck in to get the car driving.
@@DeanofMachines Not as I recall. You should go through the manual though as there may be specs to check. Wear of the brass part of the gearbox cover from the shifter cross pin seems to be a common problem. I fabricated sheet brass pieces to fit in there, but it's too early to tell if it'll last. I think someone in the UK sells rebuilt covers on an exchange basis, but they're not cheap. Good luck!
@@103erik Amazoncars in the UK does the exchanged cover deal. It's too pricey for me. I like the brass/bronze sheet idea. This'll take some pondering me thinks
1989 for the B. wall. Thx for getting after this online. I haver a J type. it really helps us RUclips mechanics. I recommend power washing that beast of a trans before taking it apart.
I'll be road tripping this car in September and I NEED to at least drive it before then. I chucked an M40 in the car for the time being. Hoping to have brakes done soon.
That M41 looks like toast. Here's hoping that the replacement looks/works a little better. I hope you get it installed before your trip. Adding the M41 was the best thing I did with mine.
Thanks again for letting me steal it for the weekend! It's the only reason I want to get an OD unit in my car for the trip. It's nice to engage it and just putt putt along
Regarding the comments above when switching from a M40 to a M41 with OD - yes the tunnel may make it fit - however, wouldn't you need to change the driveshaft to the diff - or am I missing somethin? @DeanofMachines @@DeanofMachines
@@RonAskew-ey5gk Good question! It depends on the car you have. The early cars had a different drive shaft than the 66/67 that I own. It would take a bit of research but the info is out there.
That overdrive unit takes up almost as much room as the transmission itself! I were thinking about installing one in my Amazon, but see now it would never fit. Would need to replace the tunnel. Interesting to see the gearbox being disassembled. Doesn't look too bad with the right tools at hand. Perhaps I should get a second gearbox myself and have a go at rebuilding it.
Overdrive probably wasn't a thought in 1958, unfortunately! It will not fit my '58 Amazon without cutting and welding in the tunnel. I've looked underneath, and there's just enough room for a normal gearbox before it slants down. :-)

@@DeanofMachines VP Autoparts has most of the parts you need. Layshaft is $72, sync rings $25/ea., shift dogs
@@103erik They are really good about getting parts to me in a couple days. You didn't notice any other damage that concerned you?

Your pointing hand finally healed. A miracle.
Its back and smaller than ever!
Transmission work is always an adventure😊
You got that right! I'm gearing up for round two. No pun intended...

Happy to put it out there if it helps someone!
I can relate to your efforts. I’ve spared every expense possible on my 66. It runs.

Wow deep cut, Nancy Kerrigan," Why me, why me"😢 also those jalepino poppers looked yummy and the volvo contenr was good too!😉
Chucko! Welcome back! Its always nice when you show your face around here
10 seconds in and I’m here to celebrate the no-more-black-tape Mickey pointer!
I still have it. But the new mini one is metal handled and collapsible.

I have done everything to my Volvo when I was younger. Now I’m of the mind to let other people bang their heads over things. 🤣
Sometimes its best to pay someone else to deal with our problems.
😮 that’s a project and then some, interesting to see how you are going to get it going again, good luck 🤗🤗🤗🤗
Thank you! Its going to take some parts and a lot of time!

I think your videos are great! Thank you for so much useful information!
Glad you like them! Do you have a favorite?
Always something....
You think everything is fine until it's not fine.
Nice dive into the trans Dean. Looking forward to seeing how the rebuild goes. Thanks for lots of details on examining the damage.
I was very surprised to see how banged up it was. Hopefully I can get a deal on a complete one!
Oh man, we still get product made in 2023 that has Made in West Germany stamped into it. They do not let you forget.
To be fair, it's usually pretty robust!

I highly recommend giving it a shot and seeing how it comes apart first hand
You should not need to replace your tunnel to fit an OD in an Amazon(Unless it's an early car)

@@togst Oh for sure. The early cars are MUCH different than my 66 and 67
Wow…that is not good. Much good luck with finding a substitute transmission and rebuilding the overdrive transmission.
It's a bit sad to see, isn't it? I've already lined up a solution I think. Now I just need to make it all happen.
You seem to know lots about the transmission and such. Do you have a repair manual?
@@t.g.998 unfortunately I do not have a manual. Just looking on the interwebs
Why am I so sad about this transmission. next chapter: tv tray port job.
Atleast the motor is holding it together.
Can't go wrong with a good gearbox strip and rebuild
That's 1 of the smallest iv ever seen

I have dreams of turning one into a toaster.
@@DeanofMachines I dare you to 😂😂
