I have a Mark 3 Spitfire that was upgraded by Jigsaw about 3 years ago to a stage 2 engine with a Type 9 gearbox (supplied by Frontline), amongst other mods.
It has had continual gearbox and clutch issues since day 1 and after the fourth return to Jigsaw and another big bill I lost faith and refused to return the car to them unless they undertook to honour their warranty for work done i.e. no cost to me.
They didn't... we fell out - and I managed to kill the then horrible grinding noise with a clutch fluid bleed. It had been returned to me with a new clutch cylinder!
The old problem is happening again - clunking of gearbox under load - suspect probable bearing failure.
Has anybody else had this happen to them with this conversion?
Can anybody recommend a specialist to look at it - the car is gorgeous to drive when it works!
I am based in Berks but it can go wherever to somebody who knows what they are doing!
