My problem started out with the normal od lock and unlock issues. I cleaned all the grounds and tightened them and did the same with the battery terminal connections. That seemed to solve the problem for about a week and a half then it started again. I ended up replacing the APPS and that worked for all of three days. Recently I have replaced the alternator along with the brake light switch. Now when I drive it if I barely accelerate the rpms will shoot way up to 2500 or so. It will shift normal when doing this however it will usually start the od lock and unlock a few minutes later. it will lock and unlock several times before downshifting a gear and sometimes staying in third. sometimes it will downshift without warning going 75 mph down the highway. I have tested the new alternator to make sure it was good and not sending to much AC current and it checked out fine. I am at a bit of a loss on this one. Any help would be great.
