Gear selection problem in a 1992 2.4 Diesel VW T4 Transporter.?

Question

I've had the transmission oil changed, and checked the linkage, but still have intermittent trouble selecting 1st and 2nd gear, mostly from a cold start. At what point do I know that a new gearbox is the answer? Obviously I want to know for sure what the problem is before spending out a large sum of money. Is there a common fault on these vans? Can anyone recommend a garage to make some checks, or a gearbox reconditioner, in the south of England? Thanks.

Answer 1

Answer 2
