well heres one i hope you guys can help me with. when driveing in overdrive trans will shift out of lockup but only between 50-60. been two the dealer two times and thay sead my linkages were bad and put some springs on the them. but it still does it and thay don"t have a clue whats up with it. anyone ever have this or know whats going on with the trans. thanks

 

1. Most dealers can't fix a 1995 CTD. Don't go there.
2. I've never fixed this problem, but I have seen it discussed on this forum many times. Do a search.

 

Check your TPS.. mine did about exactly what you saying... hope this helps
