Did a search and couldn't find the transmission TSIB.

Going in for oil change tomorrow and hoped to get the TSIB done at the same time. I've found it's best to have the printed TSIB in hand when I do stuff like this, so if anyone has a link to it, I'd appreciate it.

Thanks!

Thank you!

However, I don't find the software "flash" update for the auto transmission I've read about here. I don't need the one for the 2007 - which was for hesitation from a standing start - the one I want is for occasional rough shifting and sloppy downshifts.

Anyone know that one?

Oh, well. I talked to my service writer and he said there isn't one for the LS460 - just the GS and ES.

Guess I'll live with it.

I can only tell you that my service record reads:

Dealer Reported 04/28/2009 Lexus of Cherry Hill 37909 0291537 HESITATION/BUMP FEEL UPON ACCEL FRM STOP 07LS460/4 ECU Reprog. Performed

It's been much better since...

Do you mean this TSIB?

No - mine doesn't have a hesitation on acceleration, it just sometimes shifts weirdly, and if I do a sudden acceleration from, say, 35 mph, it will often downshift with a *clunk*.

And I guess all of them do the over-revving thing whem you downshift, like it doesn't want to go ahead and upshift again and get on with life ...

I had experienced some random harsh low shifts. Once it felt like I was rear ended.
