Exactly my thoughts as well, Lav. After the initial issue of the hose coming loose and the fluid loss, the topping off and correct filling procedure fixed that particular issue. The TSB definitely helped the pre-existing shifting issue.

More knowledgeable members may disagree and hopefully will chime in if they do.

Go Dodgers!
Yes I was wondering that as well, if it's okay to drive in S all the time. Like you, I wouldn't imagine it being a problem but you never know. I'd rather just bear it until I get the TSB done than cause any issues by leaving it in S. Other than the lurch, the tranny is flawless. Shifts beautifully. Let's hope someone will chime in!

I put the car through its paces this morning in areas that typically caused it to downshift hard, and it shifted smoothly. Very happy with the update.

It's like I'm driving the BEST possible car to sit in traffic like this, but not when I contantly have to baby it to avoid that unnecessary downshift. Trying to stay above 13-15 MPH here is almost impossible, and if you don't, it will needlessly downshift to first. Hence the "lurch" and "jerkiness". Transmission shifts beautifully, however.

Does leaving it in "S" actually "fix" this issue? That would be amazing as a temporary fix until I have the cat serviced.
If your car jerks when coming to a stop and also doesn't downshift properly,then it's most likely the the engine ecu. My 06 gs430 had this problem. I ended up putting a used trans and it was the same. After researching, I replaced the ecu and problem was solved.

I have it too. It's really not that bad... Not bad enough to replace the transmission..

exactly the problem i'm having! Similar "lurch" and "jerkiness" in slow bumper to bumper Bay Area traffic. Did D/F #1 last year. Dealer did the recent D/F. Indy said they did the TSB but maybe got it wrong or something. May go to dealer and have them check.

Yikes yeah it's the worst. We moved away from LA about a year and a half ago; luckily here in nice, medium-sized Knoxville the issue hardly ever presents itself because here you can actually attain a cruising speed, and literal bumper to bumper gridlock is very rare. But if we were still out there I would have gone to the dealer, too. That lurch was beyond frustrating out there in that traffic.

Hope you get it sorted out! Trust me I know how annoying it is in a huge city with traffic like that!

Thanks. Yeah it's irritating but still a great car. Tried -S- and it seems to work (on an empty country road anyway). I don't have to deal with gridlock very often so it's not a huge problem. Congrats on Knoxville.
