I have mentioned this before. My car had never shifted smooth from 1st to 2nd since I bought it new with 20 miles. I changed the transmission fluid at about 13K miles with Amsoil GL-4 fluid. The Amsoil worked great, it got rid of the notchiness 90% of the time. The only issue I had was that the problem came back within 3000-4000 miles. Since the oil is expensive, I decided to try my luck with Redline oil MT-85. When I initially put it in, I would get smooth shifts 80% of the time. Yet within 200 miles, the smoothness was completely gone. Now I get a notch every 3 or 4 shifts, absolutely annoying. So if you are ever in the market for transmission, I highly recommend staying away from the redline. You might end up making a $80 mistake like I did.
