Hello,I'm newbie with BMW. Got my e36 320i M50b20 manual ORIGINAL (stated by previous owner)I'm having this problem with my gearbox. Mostly in the morning after cold start I put in the 1st gear. When I release the clutch the is tendency to jump off the neutral. Or traffic light when engage 1st gear it will jump back to neutral. But not everytime. But once a while only. Check with my mech 1 say gearbox Sudah kong Liao. 1 say dunno wat selector kong. 1 say clutch kong. Seems like something kong. And then mech says this gearbox parts Susah dapat. Another mech friend say straight buy 325 gearbox. Walau. So what u guys suggest??
