Yes, that spline destruction looks very much like it has been caused by the lock nut not being locked. I seem to recall Toyota did have a problem with that at that time so it strongly suggests that's the original gearbox. Not that that's much help as that gearbox looks pretty rogered...
There is another error in the manual (depending on which manual you have, 2 very similar are available online). Following the assembly procedure at the point of tightening the big plate over the 2 bearings (x5 M8 screws) it says to go for 42nm when the correct torque is 21nm. It can be recognized looking at the exploded view (also in the manual) or checking the same procedure on the other version of the manual.
@@EnginesandUnfinishedBusiness if it's broken and useless then theres nothing better than to pull it apart and find out why it's broken and useless :^)
I would say the fault was the bolt by either poor fitment previous or wear. Being loose would cause the gear to chatter on the shaft therefore create the syncro to not engage fully and letting the gear pop back out also groan but at higher speed not noticeable!
Be happy you need a new trans. Rebuilding one without the proper tools and equipment would be a nightmare. By the time you buy a press, some tools to help press parts on/off the shafts and a dial indicator, you may already be at the price of a junkyard trans. I tore into a manual trans once. The clutch master cylinder failed when a novice manual transmission driver was behind the wheel on a solo drive. She didn't realize the clutch wasn't getting disengaged. "Stuff" happened and the car got stuck in first gear. In the tear down, found that a syncro was stuck to a gear. Threw everything I had at it, including fire and a 12 ton press. Broke the shaft trying to get the thing torn apart. Ended up buying a junkyard transmission. I was looking forward to the challenge of putting that thing back together too.
That was our thinking, to repair it we’d spend more on tools than the cost of a used transmission, and even then there’d be no guarantee we’d be able to fix it 😖 it was interesting to get look at gearbox internals though 😊
I'm going to guess it's an MGTF... Boxters, Elise's, exiges, vx220's are all quite expensive..... Though they did say it was a project.... Nope! It's gonna be an MGTF!
Guarantee the spline damage was due to the loose lock nut, I've had exactly the same issue happen with the output shaft to sprocket splines on my motorbike before. Without the gear retained properly it can wear sideways on the shaft and chews up the teeth like that.
Interesting, thanks for the info 😊 it’s surprising that it managed to come undone as its reverse threaded, maybe it was never installed correctly from the factory 🤔

I have the exact same car as you, same year, same model same colour! Loving the video series keep it up!
Samesies!
that cardboard diagram bolt holder is genius!!!
Thanks! It really helps as I have a terrible memory 😆
I want that new project to be a Lotus. It'd be a lot of fun to watch
everybody knows gearboxes run on pixies and black magic .. once you open one you can never get the pixies back in
On the plus side, our workshop is now full of pixies 👍
Happy birthday Matt, like the happy Gilmore reference too!!!
Interesting video seeing some of the internals worn like that.

Brave work indeed. This would scare the living crap outta me! Great work. fascinating to watch...
Yeah, not sure we would have been brave enough to crack the gearbox open if we weren’t already pretty sure that a new gearbox would be required 😖

Lotus. Any Lotus, tho an Esprit would be incredible. Also Fiat X1/9.
Hey could u make a video taking the diff out of the trans

At least you didn’t completely break the top housing like I did
Hmm... an Elise? Maybe even a VX220!
I wish, The VX220 is my all time dream car!! - Sophie
Happy Birthday Matt 🎉🎂🍰🎁🍾... is the new project and mg midget ???

Happy Birthday! Also... Do you have a Vauxhall version of the Pontiac Fiero in the UK?
Wait... Karmann Ghia...nvm that's still rear engined.
Nope, no fieros in the uk 😕
We call snap rings Jesus rings. Like Jesus Christ where did it go
Do I detect a few AvE references?
Maybe some sort of 80s Mid engine Fiat?
Smart Fortwo...
Mr2 gearbox can works an a 3s engine
I'm going fiat x19 too or bond bug ?????
I like your name, it reminds me of bread.
I bet your new project is a 1998 Honda CB500 Motorcycle with 55,000 miles.
That’s amazing! Got any predictions for the lottery numbers? 😂
Umm, 12?
honda beat or Autozam AZ-1
I dont care about your birthday, we are here to watch the mechanical videos
MGF!
Fiat x1/9 or a MGF
As an American, I have no idea WTF Yorkshire pudding is. Sounds interesting though..
Matt Huhn ...You've never seen the fluffy bun things you pour gravy over?
Sadly no...
That’s sad you have never tasted the delights of a Yorkshire pudding. My thoughts are with you.
Getting a Porsche Boxster I bet
We forgot to say in the video that it only cost £535, definitely rules out boxters 😂
Nsx
Supra?
not mid engined
🤦🏽♂️
