kam-325i 5 Report post Posted September 28, 2015 (edited) Hello All. Ive got a random "crunch" whenever my selespeed changes into 2nd from either 1st or 3rd, It does not happen all the time, but its there now and again, the same noise as though the synchromesh is worn. I want to replace the gearbox, I heard that there is two types of selector rods fitted to geaboxs, and that an early selespeed unit wont fit a later box, is this correct, or can I just us any 5 speed manual gearbox. Car is a 2000 156 2.0TS. Thanks chaps. Edited September 28, 2015 by kam-325i Quote Share this post Link to post Share on other sites
Smaky 73 Report post Posted September 28, 2015 You can use any SELESPEED box from either a 156, 147 or GT, but crunching in 2nd is normally just a clutch rod and calibration, but there is always debris involved and it's best to strip and clean out the gearbox. 1 Quote Share this post Link to post Share on other sites
kam-325i 5 Report post Posted September 30, 2015 I was kinda hoping for that answer !!! Clutch rod should be 28.5mm ? Quote Share this post Link to post Share on other sites
Smaky 73 Report post Posted October 5, 2015 28mm - 28.5, shorter the better Quote Share this post Link to post Share on other sites
