Transmission Issues
Want to see if anyone has any experience with two different issues I've had so far.
1. Sometimes, when shifting between Park/Drive/Neutral, I experience a jerk (not all the time though).
I've read a couple threads, where other LS500 owners experience something similar.
Is this "normal" for the LS500s? Or early signs of transmission failure?
Don't know if it's worth mentioning, I have the automatic emergency/parking brake feature on.
So the emergency/parking brake turns on when I put the car into Park.
Note: I have the Luxury Package with Air Suspension.
The rear struts raise up when in Reverse and then back down to regular height when in Drive.
Don't know if that may contribute to what I'm experiencing.
2. I believe this is common for LS500s....but does anyone else experience a delay in throttle response?
Happens very rarely...
Sometimes I hit the gas and the car goes abnormally slow, then randomly jolts and picks up speed.
Turbo lag perhaps?
Here is a thread of other LS500 owners with the same issue (https://www.clublexus.com/forums/ls-...-purchase.html)

The jerk is not just with shifting into Reverse...but just between Park/Neutral/Drive in general.
It doesn't happen all the time, just sometimes.
You haven't had that at all?

Did you do the TSB?
It may be due to the jerk who designed the shifter.
I suppose the shifter in my ‘02 LS430 is too old fashioned, but it works flawlessly.
See how beautiful it is:

The different shift modes seem fairly useless too. There’s not much difference in acceleration times whether I am running in Normal, Sport, or Sport+ other than
more noise from the fake noise generator thingy.
I pretty much pamper the LS500, although I do full throttle runs often, leaving the shifter in “D”.
Top three gears I believe are all overdriven, so they are pretty useless in town. The 10 speed, coupled with the very high ( low numerically ) final drive ratio makes for an excellent interstate machine.
The ‘02’s five speed works flawlessly after 23 years. I got my very first transmission fluid service at my Lexus dealer this year. It doesn’t jerk, slip, or leak and performs flawlessly.
I hope the 10 speed holds up as well. Lord knows what a new 10 speed might cost in a few years.

But based on the issues that the TSB is meant to address, I don't know if this will technically resolve my issues.
CVT and V6 TT feels like a downgrade to me, conceptually.
Do you ever get the delay in throttle response?

It surprises me only because its rare occurrence. Seems as if its on the same road and and I get caught at a light unexpected at a certain speed.
since reading this I am more aware of backing out of driveway and trying to replicate "the jerk". Perhaps I have finally mastered this type of transmission switching as not to engage the gas sooner then its actually in gear? Maybe?
