I'd use the best parts you can get we just had our gearbox fixed to the tune of £2200 tho we were been taken for a ride as tinda lee were adamant that a 2.8 crd has a 6 speed box in it and I know it's a 4 speed box it went in with a niggle before box stuck in gear and having been told rebuild included sensors ect it didn't, is there any trust left in garages anymore to make matters worse there health check reported low oil, it wasn't, low tyre tread... They wasn't they originaly said £3000 all in I did lots of research and found other places were 1500-1650 so I complained did my homework and got them down to £2200 having found receipt from gearbox fluid change they had used ordinary fluid not our recommended oil I believe this is what killed my box
