my buddy has 07 gs350 and we were driving to a local casino and experienced a transmission slip on the freeway incline entrance. The car hesitated, almost looking for a gear, and with a "thud" sound, the car jerked. I have 06 and never experience such thus arising the question, is it the transmission problem or something else? The car currently has 69k miles and he is only owner.

 

Don't worry unless happens aa few times

 

i have this issue on steep hills in seattle with a full load.

 

I hate to read something like this on a car I just bought although mine is a '11.
Reminds me of the Acura TL-S I just traded in.

 

Update:

Currently @ the dealership and my friend's gs350 needs a brand new transmission but its covered under Powertrain warranty. Talk about cutting it close, he has 67k miles and the warranty expires @ 70k.

 

Powertrain warranty on his 07 GS350 should have been extended to 6 yr / 100k per the letter we all got after the valve spring recalls.

 

I don't like reading this either as I have felt similar symptoms on my car. I am planning to take it to the dealer for a transmission drain/refill. I am at 90k miles and no warranty.
I am screwed if its a tranny issue!

 

gs450h is cvt should be different tranny

Well I had the tranny drain/refill done today and all checked out okay. Tranny is in good working condition. Lexus tech said the oil looked good for 90k miles. Glad I decided to get this done now.

Not sure what I felt those past couple of time but seems to have been nothing.

 

can anyone confirm this?..i just hit 72k and dont know if my car is still covered under the powertrain warranty..couldve sworn i felt my car slip in and out of gear the other night when i had put it in reverse but am not sure..

 

Sure, I can confirm what I got. Sorry about the quality, I just found the letter and took a quick picture of it with my cell phone. That $1500 just expired and I didn't even use it

 

damn, i never got that...does that mean my warranty didnt get extended?

 

if you got your valve springs replaced in your car, then the extended transmission warranty is given to you
