I bought the lc300 from 09/2022 until now, it's been more than 2 years. However, Toyota still hasn't released a fix for the gearbox. My car shifts jerkily from 1st to 4th and downshifts from 4th to 3rd. Is Toyota ignoring the lc300 and no longer cares about it?
Good news for those experiencing similar problems. Today I used this grease to lubricate the drive shafts and the problem is 80% gone. Pump the grease until the black grease overflows. As for the long shaft, pump until it budges. well worth a try.
NLGI 2 grease.
