My 02 Corolla gives a jerk when shifting from reverse to front gear. This is
much more noticable in colder climate. I came across a random article on
internet which mentioned that the automatic transmission could be bad? My
car has 53000 miles and I had once changed the transmission fluid around 50K
miles. Any suggestions?

During cold weather, the engine takes longer to warm up and so it idles at a
higher speed for a longer time. The higher the idle speed, the more shift
shock you will experience when changing directions.

I doubt if the transmission is bad. I would have a dealer take it for a
test drive for a professional evaluation to determine if the amount of shift
shock you are experiencing is normal or not.

If the shift shock is excessive, possible causes are idle speed too high and
bad engine or transmission mounts.
