I'm probably going to have them do it one more time next month to get a higher ratio of new fluid in the car.

Was this only when in manual mode? How much did you pay for the drain and fill?

Of course I wasn't aiming for change more maintenance but still I thought I may loose the 3rd gear funny business but did not.

My hard shifting was in automatic mode, not manual...that's what improved. I get little/no hard shifting in manual mode, regardless of gear(s).

My IS 200t has done the same thing since ive had it for over 2 years now. I bet you notice it worse when its colder out too or in the mornings. Interesting enough my driving style has adapted to the jerk and i just ease into the breaks differently ahaha.

What is the engine doing during this? My LS430 had that problem and it was a sticky throttle (throttle not closing due to being somewhat gummed up). Toyota dealer sprayed the intake with cleaner and problem was solved.
