Hi Folks:

My 2003 CTD developed sudden tranny problems (as in, stopped at a gas station with no problems, then drove away 2 minutes later with several issues).

First, I noticed that the tranny no longer shifts into OD. Second, the take-off from stopped in 1st is mushy, like its slipping. Third, the gear indicator square on the dash does not show the "square" around the gear number when the motor is running. The indicator light is there for all gears when the ignition is in the "first" accessory position.

Have tested the transmission range sensor; it did not test out per the factory repair manual so I replaced it - no change or improvement.

No codes are showing on the dash display.

The truck has 112K on it - no issues with the tranny up until this incident. If anyone has any ideas or experienced these types of problems I would appreciate some suggestions.

Many thanks,

Andy
