Hi all.
Could any of you tell me if there are any differences between the T5 gearboxes across the TVR range? I
I know the bellhousings will vary between the cars and that the later ones had the S10 tailhousing.
Apart from this though are all the input shafts,output shafts and ratios the same? if so, I assume a Cerbera box would fit a Chimaera would fit a Tuscan etc.....
Many thanks, Chris.

Thank you all for the helpful information.
It would appear then that apart from the differences in the tail housing, all T5 boxes specified for the Chimaera, Griffith and AJP V8 Cerbera should be interchangeable, I assume all the input shafts on these boxes are the same?
Many Thanks, Chris.

Just to mirror Dave's (Chimpongas) post, the T5/3.45 BTR diff combo in mine is coping well with lots of horsepower, torque & running in the Speed Championship. It had the famous 5th gear mod around 8 years ago, all I do is change the fluid regularly and have had no problems, (although this could of course be famous last words!!!).
Just out of curiosity, and I know I have asked this before, but does your gearbox make any audible noise when the car is ticking over? Most I have heard have been near silent, even with the roof on.....Thanks for the replies.
I know I am going on and on about my gearbox but I still feel it's not right.....
All of the cars I have sat in and listened to seem quiet, almost silent . Mine is a year 2000, 31k miles Chimaera.
Mine still makes a "whirring" noise which is distinctly audible on tickover. The box has been out four times and "rebuilt" (my definition of a rebuild would include at least new bearings but they say they're ok) by three different specialists and none have cured it and I have spent (wasted?) thousands and am at a loss now. The last person reccomended sound insulation......
The gear change is better than it was but the noise is still there! I know I'm a perfectionist in some ways but it's not right....
Anyone got a reasonably priced T5 for sale?!!!!
Regards Chris

Thanks for the advice about this.
The first "specialist" took the box and new bearings supposedly fitted but the gearchange after was horrid and the noise still there.
The second "specialist" told me that the bearings had not been replaced so they fitted new bearings to the mainshaft only and a new 3rd gear synchro. It was still noisy so they took the box out and increased the preload on the bearings.
After about 1500 miles and out of "warranty" the 1st to 2nd change often baulked so having lost faith I took it to another specialist who took the box out and replaced the 1st gear synchro. I asked for a full rebuild kit to be fitted but when I picked the car up they said that the bearings looked ok but they had fitted a different gearset to try and eliminate the noise but that had made no difference so they hadn't charged me for this. I suspect my gears were better and newer to be honest. They told me to add extra sound insulation.....
All three people who have had the box apart are well respected specialists often recommended on this forum. Perhaps they are all missing something? To the best of my knowledge a complete set of bearings has not yet been fitted and it still makes this noise. New release bearings have been fitted each time the box has been out, new bronze spigot bush and last time a Ford needle roller spigot bush was fitted. I am at a loss now as to what to do. All I know is it shouldn't be noisy like it is!

No ducking needed so no need to worry!
The noise occurs when the car is stationary so I doubt it will be the diff. Pressing the clutch in eliminates the noise completely.
New release bearings at each removal and new spigot bushes too suggests these should be ok.
I am not expecting my car to be like a Rolls Royce in terms of refinement and noise levels but a mechanical noise that shouldn't be there does bother me when it should have been sorted. I sat in a similar age and mileage car to mine (amongst others) at Central and even with my ear firmly on the tunnel could not hear anything like the noise mine is making.....
Thanks again. Chris.
