Robust and reliable, the XR2’s BC fivespeed gearbox rarely causes much grief other than age-related wear and tear.
Typically, the gear linkage may feel sloppy; the gearchange was pretty vague as new, but you shouldn’t experience difficulty selecting gears. Crunching or notchiness could also be due to worn synchromesh, especially on second or third gears during downshifts.
A little noisiness is to be expected, but loud rumbling while driving means there’s not much life left in the ’box.
Fortunately, a gearbox rebuild isn’t the end of the world. Remember, though, that the final drive ratio was lowered from 3.58:1 to 3.84:1 in autumn 1986, and the later setup means slightly sharper acceleration.
The XR2’s standard clutch was a little 190mm plate, which doesn’t enjoy being drag-raced or coping with modifications. Check for slip by selecting second or third gear while stationary and letting your foot off the pedal; if the car stalls, the clutch is fine.
