I have 93 RX7 with a MT. When the Tranny is cold it shifts into all gears, although on GL5 75w90. Before that I has using Neo 70-90HD and had the same problem. When I had bought the car it supposedly had Redline MT90 in it. It is hard to remember since that was 2 years ago, but the problem seem to happen less, but still present.
Do you guys think it might be thinning out as it warms up? Or maybe the synthetics are just too slippery for the sycros? I am debating whether trying dino juice in the right weight or the new amsoil 75w110. What do you guys think?
