My 84 190e 2.3 w/ 190k on it. A month ago became hard to **** into the lower gears (1st and 2nd). After a while and a stretch of 100+ degree weather the shifting became worse. It liked to pop out of 3rd gear and made a whining sound in 3rd. Two days before it finally got stuck in gear for good, I heard a clunking noise when accelerating in second and was reduced to the use of 3rd 4th and 5th gear. Sounds like a bad transmission. Is it normal for a manual trans to go out.
