Evening all,
After a bit of advice, I have just finished my car except for paint and have been trying to get the miles in to iron out any potential issues, unfortunately I have found one that now needs ironing out...
So far I’ve driven around 150 fairly sedate miles in the car and they have been largely problem free, mainly just small tweaks and tightening everything multiple times. However on my last drive I developed an issue I think is gearbox related, I have developed throwback through the gear shift, it is only noticeable under load so I can drive around at 25-30 mph with no real issue but as soon as I accelerate beyond that the gear shift noticeably throws forwards and backwards and the car surges, there is also a knocking sound from the read, something is not right. I have put the car up on ramps and checked all mountings between the gearbox and the engine and the engine and gearbox mounts to the car, all seem fine, next I’ve removed the driveshafts and checked them and the CV’s and again all seems fine so now I’m stumped.
The gearbox was reconditioned by Chris Cole about 6 years ago but has only done 150 miles since (yes I filled it with oil), I have asked Chris but he was not sure what it could be either, he did say he would take a look at it but as he’s so busy it would not be until after the summer and I’d really like to get this sorted before then as I have the paint booked!
I appreciate its not much to go on and I will try and get out with a passenger to assist in the diagnosis too.
Any suggestions as to what it could be will greatly appreciated, fingers crossed for an easy fix but I’m sure that’s wishful thinking...
Thanks
