I found an LS430 thread where there was a TSB for low speed shifting:

Anyone know if this is a common problem for the gs? I have a 99. I've done two drain and fills recently. My transmission shifts fine except for this one slow speed turn in my neighborhood. It never wants to engage immediately and slips a bit.

....maybe your transmission is starting to die

Might be your car. We don't use the same tranny as the 04-06 LS430.

i have that same problem in mine. my friend has the same problem as his as well. it seems to be common. its only when you slow down to make a slow turn. from a dead stop it shifts perfectly. i heard there was a reflash that needs to get done for the ecu and it cures it.

I think it's a software issue as well. My car shifts perfectly from a dead stop.
