Hi everyone. Got the codes from my gearbox yesterday p2500 p220a p2502. Can anybody help me decide what to do. I havechanged the oil and filter and check the levels everything ok. can't really afford to put a reconditioned gearbox in so looking on eBay at second-hand ones but very nervous about going down that route. Does anybody know how long it takes to roughly change a gearbox over?its C Class CDI Estate. Really don't know what to do... any advice would be great cheers everybody.
