1990 Dodge Dakota Question: tach surges at 60+mph



rondu67, 3.9L V6, South Bend, IN, May 16, 2011, 20:55

as i'm driving at 60+mph, it seems like the tranny down shifts and the tach revs up to about 3000rpm, then goes back down, then back up and so on. What could be causing this? Tranny was recently rebuilt

    Sounds like a possible issue with the torque converter or torque converter clutch. I would advise you to return to the place where the transmission was rebuilt and have them recheck their work.
