I have just bought a 2001 GS300 with 45K miles, and I want to flush the tranny -- requires 16 quarts of Type T-IV fluid. My local Toyota dealer sold me a product in bulk called BG 3134 (4 gallons in a single bladder) that he says they use instead of Type T-IV. The dealer technician tells me they use it in Toyotas when they do a transmission flush.
Anyone try this product, and do you know if it will harm the GS transmission?!
