when the engine is warm all the gears work fine
My car has 100000 miles.
My car has a manual transmission.
Hi there. Try using 75/90 Synthetic transmission oil in the transmission. This may help the transmission for the shifting issue. This is a normal condition during a break in period, however, with 100,000 miles on the transmission the synchronizers could be worn out for the gears 1st and 2nd. I recommend seeking out a professional, such as one from Your Mechanic, to help you diagnose your transmission issue.
