Jerking from Torque Converter, Overdrive, or Cruise Control?
Hey guys I'm confused about what might be causing this. I don't know if its the torque converter locking/unlocking, the overdrive going in and out, or if it's related to the cruise control.
The symptoms seem to occur while I'm using the cruise control. There is one section of road on my way home that has a very slight downgrade to it about 30 yards long. But like clockwork, if I have the cruise control set at 60 MPH as soon as I hit that slight downgrade my truck jerks like the tranny is going in and out of overdrive. Once I'm past the small downgrade it smooths out, and drives perfect. I know it's not a bumpy defect in the road at that spot because it's happen to me one other time on a different road.
I've done all the regular maintenance on this truck and it otherwise runs/drives like new. The only thing I haven't done is flush the tranny and install a new filter. It doesn't have any indicator lights or anything on and I hooked several scanners to it and it has no codes.
So does it sound like the torque converter, overdrive, or a cruise control issue? Is there a module or sensor or something that can go bad and cause these symptoms? I hope so. I don't really know where to start.
