Been driving a car with a manual transmission for 6 years. I never had to replace the clutch but the transmission recently blew up on me. I was aware that my car was leaking transmission fluid for quite some time so I assumed that was the reason for the car's transmission failure. Upon further thought, I started questioning my shifting habits. Now I know all the basics, like don't hold the clutch down at a red light, don't ride the clutch blah blah blah. My questions are a little more specific to my own habits. For example, When I am in 1st gear (and lets say I am in the drive-through at a fast food place) and I want to inch forward because some space just became available. Is it OK to "half-shift" in order to inch forward in tight spots? (by "half shift" I mean this: So I am in 1st gear, I release the clutch halfway and give a little gas in order to get some acceleration, but then immediately depress the clutch and gently brake before fully engaging 1st gear so I don't crash into the car in front of me) Would a scenario like that damage my transmission?
Another question is if bad rev matching would damage the transmission. I know it could screw up the clutch but my main concern is about the transmission?
Is it just a myth that with manual transmissions the clutch will eventually need to be replaced, and the transmission should go for 100s of thousands of miles no problem?
I have a friend who insists that bad shifting will only damage the clutch...but I don't know if I believe him.
If anyone can tell me any other ways that bad shifting could damage the transmission I would love to know! Thanks!
