I just replaced my tranny. It was working great
About 3 months ago, during my 25-mile commute to the ambulance base where I volunteer, my transmission started acting up. After a few minutes of driving normally, it started to upshift very hard. Each upshift was accompanied by a noticeable "Bang!" and it felt like the car was hitting a pot hole.
I immediately stopped and checked the tranny fluid at a service station, but the fluid level was fine and it didn't have any burnt smell. The car has 76K miles on it and the transmission fluid was changed at 50K per the maintenance schedule. I had no choice but to continue on to the base, driving very gently.
I made a stop about 5 minutes before arriving, to pick up dry cleaning. I was in the cleaners for about 8 minutes, and when I came out the hard shifting had completely disappeared. The car drove smoothly for the next 3 months.
Now, this problem seems to recur any time I drive the car even remotely hard. We're not talking about full-throttle accelerations here, since my everyday driving stays below 2500 RPM to save on gas. But if I'm in a hurry and start driving a touch harder - crossing over 3500 RPM - then the tranny will start shifting hard within minutes. Let it sit for 10 minutes with the engine off, and the problem is gone again
