My Griff is just on 40k miles, but the mileometer has stopped altogether at 39,999, and the trip counter is not running either. I am confident that it has not been clocked, but I am a little concerned. I have done about 50 miles without it working now. Does this sound familiar to anyone?
Very common. Mine stopped at 29,999 and didn't start back up on its own accord after about 100 miles ish.
Its gone back to Kings for a variety of bits and pieces, including this.
The bad news is that TVR don't stock Griff speedos anymore (which I found a bit alarming given how recent it is since they stopped building them). Mine has been taken out and sent to TVR, who will send it for repair then return it. For some reason they won't let the dealer send it to the repairer direct. Been without the car for 3 weeks so far. At least I have a Cerb Speed 6 as a loan car whilst it is sorted.
I am rather worried about TVR's (lack of) stocks of Griff parts. Some dealers still have new Griff 100's for sale - yet TVR don't hold spares for them. I thought car manufacturers were required to make spares available for 7 years after the demise of a model?
I think Speedy Cables (?) are the people who do the repairs on the speedos - someone here might be able to confirm.

It must happen with X9,999 miles on the clock because that's when the greatest force is needed to turn all the wheels over. Clearly the force from the cable or whatever can't overcome the load - like when an battery clock stops with the second hand at 9pm.
Only TVR could make a speedo system that can't do this simple task!

My speedo stopped turning at 12,337 miles and hasn't worked since. Neither has the trip.I was told it will have to go to a repair shop. I hope it starts again pon its own soon as it sounds a real pain to remove dash and speedo, get repaired (180 pds!) and reinstall.
Suppose I have done about 50 miles since at varying speeds, speedo works fine but no change to the mileometer.

yours is NOT the typical 999 rollover failure - which seems to occur because there's too many digits to rotate and not enough energy to do it (!) - it sounds like something is actually broken rather than the normal TVR 'just about do the job if you're lucky' design fault. Don't hold your breath waiting for it to fix itself!

Drop out the dash - take out speedo - clobber it a few times - replace. Worked regularly on my old S3 which had a habit of jamming.
It's the mechanical mechanism for turning the numbers over that's at fault. It's electrically driven by the amplified pulses from a sensor in the transmission, so driving hard, fast or long won't help !
