The 'box in my R33 GTR is showing signs of synchro issues on 1st and 3rd. I know there are a lot of threads out there discussing the refurb versus 2nd hand box dilemma - the box in question is a used one fitted about four years ago. Currently there are a few used boxes for sale in the order of £600 for around 40,000km but I know the risks of going the 'cheap and easy' route. The biggest issue for me, as the Skyline is my daily drive, would be the turnaround time for getting my box refurbished. Can anyone comment from recent experience? The idea of bussing to/from work every day for months while parts ship from Japan is what out me off going the refurb route last time.
