Gearbox issue, no 5th or reverse
I was driving home from Gatwick earlier and as I was shifting into 2nd the car shuddered pretty bad and started making a scraping metal sound. I've since lost 5th gear and reverse. Although I can on the odd occasion get into reverse but it takes a fair bit of doing and a good 5 minutes of time.
I heard from a few other threads that 5th gear is a common problem with this car and it shares a syncro with reverse.
Do you think this is my issue? And how easy of a repair is it?
I'll leave a couple videos below of my issue for reference:
The sound: https://youtu.be/3NaVF0rMOIM
The gears: https://youtu.be/9VAmOWdJnAs
Cheers
It's a rev2 tubby btw.

Re: Gearbox issue, no 5th or reverse
Before condemning the gearbox it may well be clutch related. Collapsed thrust bearing or broken/bent finger on the pressure plate.
Unfortunately the only way to know is to whip the box off.

Re: Gearbox issue, no 5th or reverse
Well surely if its clutch related then my other gears would be affected too? 1st though 4th works as beautifully as it ever has. I've driven it about 30 miles in this condition on my way home and I even did a quick full throttle pull through all 4 gears.

I'm reasonably certain its not clutch related. But to be honest I just want my car working again so i'm going to speak to my mechanic tomorrow. It's gonna cost me so much money but I just want it fixed.
Thanks for the input though. I invite all ideas.

Re: Gearbox issue, no 5th or reverse
Drain your gearbox oil and see what it looks like,if it silver or golden in colour then you have a problem.
Also 5th gear can be replaced without removing the gearbox,Toyota sells upgraded gear and the bearing.

Re: Gearbox issue, no 5th or reverse
Linkages perhaps ? the square brass ones can wear at the gearbox end of gear change cables you can reposition by rotating them 90 degrees to rectify, there are two, one could affect 1st and 5th at a guess.

Re: Gearbox issue, no 5th or reverse
Already replaced linkages.
With all the horrible scraping metal and grinding sounds coming from the gear box even in neutral with the clutch disengaged there is something borked in there for sure. I was reading some posts here and on other forums and other people seem to have had the same symptoms as me and it always ended up with the 5th gear syncro being destroyed in there.
There is also oil spewing out the CV joint which is nice. I managed to drive it up to my mechanic today. He is gonna drop the gearbox and i'm taking it to Steve at Rotherfield gearboxes near me. He is going to rebuild it.
Also where are these brass cubes people keep telling me about. I see it everywhere but I can't find a single picture. I gather it's somewhere under the shift lever?
Cheers
