I recently purchased an auto transmission off ebay and had it installed. The replacement trans is having a couple of issues. When driving at highway speeds it sometimes does not want to shift into or stay in O/D / 4th gear. When in O/D, if I turn off O/D, it will shift back into 3rd and the back into O/D when turned back on. The O/D light is working properly. Some times, I have to leave my foot off the accel pedal for a little while and let the RPM's drop some, before it will shift into O/D. Another thing that I noticed which may or not be related is that when cruising down from highway speeds, the RMP's will slowly decrease and decrease all the way down to idle! These are both new issues since replacement.
Any suggestions?
