I Just got this car a bit ago and I find the Auto Trany a bit jumpy. In parking lots and just starting out it is quite touchy for sure. It ALSO SEEMS TO DEVELOP A BIT OF SLACK AT SLOW SPEEDS AND THEN SORT OF CATCHES UP AND JUMPS A BIT.

DOES THIS SOUND NORMAL.

THANKS FOR THE FEEDBACK.

 

yeah the is300 has quite short rear gearing. so it feels kinda touchy. just get used to it

 

the '01 were the worst
also, some have tried a grounding kit and has helped

 

just learn how much pressure to put on the accelerator. you dont have to push that hard for it to move fast . its a bit touchy when you are trying to push it hard. learn the tiptronics its fun

 

what year is it? because there is an ECU tranmission reflash that is free by the dealer. It revolved around autos that seem to be bogging then accelerating when in the most in opportune time.

 

I noticed this tranny is a bit different from other makes of cars. At first I thought something was wrong but swapped cars with another IS guy and we both noticed how this tranny stays consistent from car to car. It's definitely different than most.

To me the car seems soft in 1st and second and hooks up really well in third. It feels like a good Torque Convertor would make all the difference.

 

i did a search regarding about the down eshift to 2 gear problems, but couldnt find anything at all.

I was wondering if its normal that when u down shift to 2 gear with the e shift it does it hard not as smooth as from 4th to 3rd.

sorry for my newbie question..

thanks

 

it's possible that it downshifts harder, coz' 2nd gear is really low and it will suddenly put a lot of stress on tranny and has to rev much higher rpm

 

so actually its normal hu?
thanks a lot romin

 

well i am only imagining what's going on from what you described, so hopefully i am not mistaking anything
