1-2 shift neutralizing when hot
At about 100k my 2000 started nuetralizing intermitently when the trans gets warm. Back when I used to work at a dealership I tore it down and found that the 1-2 shift accumulator piston felt loose in it's bore especially when compared to the others. Because I am cheap I did not replace the piston and accumulator body. I put a new seal on the piston, it felt great. Put the trans back together, trans worked great. About 9 months later it started doing it agian. I only work 6 miles from the house so it rarely gets warm enough. Add this to the fact that I'm cheap and I never tore it back down. It now has 212k.
