2006 Pontiac Grand Prix V8 Front Wheel Drive Automatic 65000 miles
I have recently noticed a couple of issues with my 2006 Grand Prix GXP.
Problem 1 - While stopped at a stop light (car still in drive and it appears to idle fine), when I slowly accelerate when the light turns green, my car feels sluggish (~2-4 MPH) then I feel something lock (like a small slam that my car just went into gear) and then my car accelerates.
Problem 2 - If I am cruising at roughly 69-73 MPH, I see my RPMs bounce up and down a little bit. Then, my torque converter will lock (at about 2100 RPMs). If I start to slightly go uphill, car starts to shake a little bit and then my torque converter unlocks (goes up to about 2600 RPM) and the shaking stops.
Are these symptoms torque converter or tramissions problems or both?
have the same problem?
