Drawing a bit of a blank so far. Don't want to go with the local auto guy who ash never done the angle gear of rear diff before. Phoned P&R in Leeds who wouldn't touch it and even warned me off faffing with the transmission at all for fear of "stirring up a hornet's nest". I know they are no fans of modding so no surprise they didn't think much of the remap plans...
...but has anyone ever heard of running into problems by just servicing the transmission?
