Hey Guys,

I have a 2000 GS300 with 70k. The transmission fluid is clean and full.

When I was driving on the highway and I am not on the gas or the tranney from about 30 ish and the car rides down into the 20 mphish i get a downshift when the tranney shifts. Its like a little jerk when you downshift the rpms rise a little about 500k rpm. This happens once in a while.

When regular driving the car shifts up and down very smoothly. If i brake or gas the car the tranney is fine.
Should I add some kind of transmission additive? or should i jsut get a transmission flush?
Or this is nothing because the transmission is basically confused on what to do?
BTW: When are regular transmission fluids changed? What kind of fluid is used?

Thanks
Greg

make sure you use the correct type of transmission fluid. either get it from toyota/lexus, or if you use a regular type of tranny fluid you need to get an additive called "friction modifier" and add it into your tranny

hey tony,

i am not sure of the fluid. any way of finding out?
i just bought the car from an old man recently.
i dont know if it was ever changed.
the fluid looks like a dark purplish red.

thanks

New fluid is supposed to be cherry red. If it is getting really dark then it needs to be changed/flushed.
