I've now had a diesel geek quick shift fitted to mt TDI 150 for over a month now, say 2K miles. Fitting was relatively easy apart for finding the gear s elector locking pin for the final adjustment. In terms of driving the gear s elector is definatly shorter in both directions. The feel is more notchy and has lost refinement over the standard shifter. Whilst driving quickly over A roads the shifter is much improved, with less chance of missed gears, but round the town the 1st and 2nd gear changes are harder to work and add to driver fatigue. Overall I'm pleased, but you must be aware that the changer has pros and cons. I will keep you informed regarding durability over the next months.
