Leo,

I have a '98 Ram with automatic transmission. What I hear you are saying is your transmission is hunting for direct drive or overdrive. This is a very common complaint from Ram owners with automatic transmissions from that time period.

Over the years this has happened to me three times. It happened when I was up to speed and around 55 mph. Twice I cleaned the ground connections at both batteries (it's a diesel) and solved my problem for a few years. The third time I had the transmission shop put in a Wiring Filter to solve the problem for ever ($10.00 cheap).

What is happening is the electrical controls for the transmission is sensing electrical 'noise' around the wiring from/to the TPS. This noise is usually comes from a bad ground. This 'noise' is telling the transmission to shift either to direct or OD.

If I were to have this for the first time I would just have the electrical noise filter put in the line.
