TOYOTA issued a recall on the LS 430 model

On certain vehicles, a tab on the collar for the planetary gear assembly, an inner part of the automatic transmission, can receive greater force than what it is designed for when the accelerator pedal is operated quickly. This could cause a small piece of metal to be torn from the collar. In the worst case, this small piece of metal may get caught in the parking lock mechanism, causing the parking lock system to be inoperative when the transmission shift lever is placed in the "P" (PARK) position. Correction: Dealers will replace the automatic transmission.
