Anyone else had a gearbox problem like this before?

[JBliss]

Hi all

Yesterday i was out for a drive. Sat at a set of lights and went for a reasonably quick getaway. Got a little wheel hop and then an almighty bang and lost all drive.

upon a brief inspection it looks like the gearbox has cracked/broken near the rear engine mount and deposited its contents everywhere.. I wont be able to have a proper look until the engine is out

The car will still go into gear, clutch feels fine, but there is no drive whatsoever.

I thought the rear mount was supposed to absorb any force, but it appears the gearbox has taken the impact. Could the rear mount be past it?



If anyone has a 5 speed box for sale, let me know!

I have a Noble spec MTX75 5-speed box with a standard open diff if yours is scrap.

i suspect the diff has gone and the box has broken from inside out !

make sure you get the atb fitted to the new box

Hmm, sounds likely and would explain the complete lack of drive.
i wonder if it was the diff or the engine mount that caused the problem. Seems like the rear mount has seen better days.

I was just about to put the car up for sale, so I'll just be replacing like for like I think.
I will get some pictures of the box when it's out of the car.

hi mine did the same half way round the nurburg and it was the diff that caused the problem.

Can and engine mount cause a problem like this?...recently i have been feeling a bit more engine vibration than normal and every now and then it can feel a bit of judder on acceleration on when cornering hard on track when suspension is on its hardest setting...somebody told me it could be tyre hopping on the limits of grip ..but for me that did not quite fit..its hardly noticeable to be honest but i prefer to catch things early and this is something i was going to start investigating..

OP... Your diff has exploded is my bet, bummer it's taken the box housing with it :-(... Shouldn't be expensive to find a replacement but the swop is going to cost the most.

Chris, I recon your drive shafts are bottoming out, mine did this on track and I destroyed the cv joints :-(
