This just started happening. While driving on a level surface at slower speeds, the speedometer works fine, and the engine doesn't surge or have trouble shifting. When I'm going up or down hill or over speeds or 40 I have this issue. The engine surge is like it is waiting too long to shift up or down and then it does so too quickly and jerks. I'm not certain if it is the 3.0 or 3.8 V6 engine.

Faulty speed sensor,speedometer,connections. Need scan test results.

Check where speedo cable goes into trans or rear end probably broken.

could be either of these issues but most likely cable or speedo head needs lubrication

Thank you, folks. That sounds like it isn't as major as what I'd been told. Do you have an estimate of how much it will cost to repair -- just a ball park, so we can set the money aside? Thanks again!!

could be 2 to 3 hundred depending on damage or condition of parts
