SRK Posted August 21, 2003 Share Posted August 21, 2003 Toyota Type IV trans fluid is synthetic, and I would recommend staying with it rather than changing to another brand. These transmissions last a long time on the dealer supplied products, so there is less incentive to switch. The synthetic gear oil may be a good idea though.

tansupplyman Posted August 21, 2003 Share Posted August 21, 2003 You could also use Redline syn. in the diff.; but match the type[wt.]; Redline is super!!!!!! Use the man. transmission fluid in any straight shift(other car!) and SPEED shift at 0 degrees!!!!! But stay with Lexus on tran. fluid---I need to change that also.
