last night on the on ramp to the highway going about 30mph, i punch it, and it downshifts to first like normal, but as its pulling it really slips bad. its like it would grab, and slip out again like 4-5 times, i dont really know how to explain it. you could really feel it surge and buck. it only happens at WOT. Oh also, when you're going about 50-55mph and as it shifts into 4th it kinda slips and revs the motor before it shifts, but its always done that. the WOT thing just started last night.
