I have a manual transmission. Sometimes on 1-2 and 2-3 shifts I get a "tick" or a slight grind. It happens more when the weather is cold. I'm worried that my synchros are going bad. I'm thinking about getting rid of the car before this happnes because of the expense of a new tranny.
Synchronizers in manual may be going away on 2002 BMW M3
First thing first, try changing the transmission oil with a synthetic (red line) product. It is rare this does not cure the problem
