BMW 535D
before my gearbox went i could hit about 70 in 2nd gear, ive had the box overhauled completely so its more or less new and the guy that did it said all ratios were the same
however, ive had the car back for a few days and i can now only get to 65 in 2nd gear
do the new components just need time to settle in or has he f**ked up my ratios?
