This thread was made in the GS430 section but the transmission is the same in our LS430's. At least, from what I understand. Correct me if I am wrong. I don't think I am brave enough to try this but maybe some will be interested. Apparently, Lexus set the position depending on the market. US, Euro, and Japan.

Here is also a shift kit available:

Guessing this only applies to the 01-03 with 5 speed as the 04-06 6 speed transmissions are sealed?

 

Honestly, I don't know exactly. The procedure involves dropping the pan. The 04-06 transmissions are not "sealed" they just lack a dipstick. It would be the same procedure for both.
