Transmission gear oil
My 01 Tacoma 4x4 has 100,000 miles on it, and someone suggested I change the transmission oil. When I drained it, it looked fine, and I had no previous transmission problems. I replaced it with Travelers brand 80-90 weight (it calls for 75-90). When it's cold, first and second gears are extremely stiff. I am thinking of changing the transmission oil again to a thinner weight. The Toyota dealership says they use Valvoline 75-90. The O'Reilly's store says Toyota recommends something called Redline. I do not have quick access to that brand of oil. Does Toyota recommend a synthetic transmission oil?
