From what I have read this is not too uncommon with Cerbies and 5th is a weak spot. Apparently some of the Gearboxes can drop a circlip that allows the Gear cluster to move.. sadly Gearbox out/strip/rebuild..

This is particularly ironic when cross-referenced to the other thread that says "a '98 4.5 Cerbera is reckoned to be the cornerstone in reliability"

Hope it's not too expensive

This seems to happen on cars which the driver has been (rightly) told to put the car into 5th before engaging reverse. This does help, but any gear before reverse will also work, using other gears instead of 5th all the time might make it a bit less prone to wear.

Yeah I have been told to use 5th before reverse which I have been doing then all of a sudden it goes tits up! You can imagine how this has gone with Mrs Bazza who I had convinced TVR ownership wasn't going to be a problem and now finds herself lending me her car for a week! lol

Is it that difficult to take the gearbox out yourself?
Its a bog standard box, and a trip to a gearbox specialist is likely to be much cheaper.

Only saying this to find out if anyone has any experience as I'm thinking about doing this on my 4.5 for a 5th gear syncromesh problem.

Hmmm time for a change of gear shift pattern for me then!

Good luck BigBazza.

Thanks for advice and support, as this appears to be a fairl common problem can anyone hazard a guess at what sort of financials I am looking at for a rebuild? I realise its only guesswork but I need to sleep this weekend and placate the current Mrs Bazza

Topcats tell me they do gearbox work, you may want to give them a call for a quote. Can't recommend them yet as I am using them for the first time at the moment.

TopCats Racing

Totally recommend them, based near Aylesbury.

Brian did my gearbox rebuild (lay and imput shafts, bearing and seals )

Call Warren and tell him Graham from TCR sent you!
(probably turn you away... )

Go create some weather...

Would be interested to know what kind of prices people have been quoted for such synchromesh issues... have a slight crunching when changing from 1st to 2nd above 5500 RPM. Was given an approximate quote of £650 from a dealer - definitely too much for now given that I rarely push the revs high enough in 1st to notice.

Walldonway, were looking at approx £1200 to take it out and do it, assuming that was the problem.

I know it's not quite the same, but once when I did a track day in the Scoob I came away with a *very* crunchy 5th gear. It would engage if you were going 60mph, but any more and there was no chance. I thought I'd shagged the gearbox

However, a quick trip to Scoobysport and some Silkolene SYN5 trans lube later and it was fine. Been fine for 60k miles since, too

If you have crunchy gears, it's worth trying some decent synthetic gear oil as it's a hell of a lot cheaper than a gearbox stripdown/rebuild. If it doesn't work, you haven't lost much.

Hi Bazza,

The Peril jumped out of 5th on the two mile straight at Bruntingthorpe and had to have the gear box out.

We took it to C D L Racing, the Tuscan race team based at Grays in Essex and they had the circlip groove machined wider so two clips could be fitted.

Apparently that is a Tuscan race car standard modification to the T5 box used in Cerbs and Tuscans.

Cost £650. approx.

CDL did a great job and I know thay have some engineers free at the mo as they are now not going to race in Aussie land.

As a matter of interest, Ray also engages 5th before reverse!!!...

Hope this helps
