Hello gurus,
I have a 93 es300. When I start the car in the morning or after 5-6 hours of rest, the car gives a jerk when shifting from first to the second(could be 2nd to 3rd too...). The problem is less felt if I let the car get heated up for about 5 minutes and start driving. It gets better as the car gets heated up. I feel very slight jerks for shifting of other gears too.

My car has 120K miles on it and has new timing belt. I have recently done transmission service on it, but no use. I have also taken it for a trasmission check and they reported no problem in transmission. I have observed considerable loss of power and acceleration from when I got the car around 60K miles. One more observation is that the problem got aggravated after changing the timing belt.

I can't seem to find the source of the problem and am worried that I might be damaging something internally by continuing driving without fixing

Please help....
