147 selespeed gears crunching, Help !

Had selespeed ecu replaced by Desira of Norwich a while ago. Car came back with gears crunching between 3rd-4th and back down again from 5th . Asked them to sort it , they said as it's a new car to "put miles on it" . Has done about 1000 miles now , still crunching.
They have now bled the clutch and calibrated it , but still crunching .They "suspect wear in 3rd and 4th gear syncro gearbox" and say it requires stripping to confirm fault.
The gearbox has only done a 1000 miles from new , so how it can be "ware" i don't know.Especially as the fault only appeared after they replaced the ecu. I suspect they don't really know what they're doing even though they are an authorized dealer, this is Norfolk and not famed for the intelligence of it's mechanics ! Should i let them strip gearbox ? or take it somewhere else ? Have spoken to alfa workshop in Herts who seem to know what they're on about .
Any advice would be greatly appreciated ,

Re: 147 selespeed gears crunching, Help !

this sounds pretty much like the same problem i had on my car when i first got it.. it was new too and i had less than 150miles on it. sent it back to the dealer since it was under warranty and they told me there was some probs with my transmission assembly. honestly they weren't very specific about it. anyway, when i got the car back the sound was gone and the job order listed the part that was changed. this is the part number 55190961 (old part #46782759) on eper described as "TRANSMISSION AND DIFFERENTIAL UNIT".

So "thkc" had a complete new gearbox fitted (parts cost about £2000), Harry I hope your 1000mile old gearbox is under warranty...
