Thought it might be my injectors or spark plugs but now i think its my tranny it does it randomly feels like its not transitioning into the next gear like its stalling then jerking....? 01 IS AUTO Trans.....

 

i just spent 300 on strusts + 2 installed, oil change 40$, gaskets 500, both front ball joints 400, and im trying to find this sound coming from the front i have no idea what it is its a moving part like the cv joint or something in the front that moves when the car moves slowing down or speeding up is when u hear it when ur going u wont hear it but youll feel it like the cars being held back by something u can feel it in the peddle now & it sounds like a whewwww wheewww whewwww whewwww wheewww wheewwww whewww....??? HELP PLZ

 

Use E Shift and see if keeping it in gear still produces those symptoms, then shift to see if it is your trans.

 

Check your transmission fluids before its to late. if your fluid looks like its darker then average trans oil then you might need to change it. Also, the trans fluid is more water then motor oil and red like cool aid. If you haven't changed your oil or dont remember the last time you flush your trans oil, change it. My cousin had problems with his transmission in his 01 IS300 and he flushed his fluid and it did the deed. Hope i helped

 

Funny you say that i was just thinking about how i should have got a flush instead of just a fluid change for the tranny....& btw DONT EVER GO TO AAMCO to get your fluid changed they over filled mine and i drained it a little it helped a little but it still jerks some.....sometimes it feels like its not catching....somebody said something to me about spyder gears or something like that?? like itll rev like its in neutral then slip into the gear and catch....& its an auto LoL not funny smh

 

i did and itll jerk but not slip but....btw the lower tranny mount the one bolted on the under carrage looks good...could this also be from bad wheel bearings maybe? i just wanna figure all this sheet out what a headache smh....

 

Did the symptoms start before or after the fluid change?

Auto transmissions are very delicate when it comes to flush/fluid change.

 

it actually started before....thats why i got the change thinking it'd help now im thinkin i should of got a flush....~_~*sigh

 

How did you know if the tranny fluid was to much? I not sure how it is for our cars but if iam correct, you should check your fluids when its running. So it may seem alot when its at cold start but is correct onces running. I would get a fluid flush at Lexus asap.

 

i was at a Lexus/Toyota mechanic shop and it was way over bro a quart at least.....but ya ima probably get a flush here in the near future it runs way better after they drained it a little....but its still jerking around 40-50 when its changing gears...it hesitates then boom itll happen...jumps forward or trys to....
