Was driving home from the track last Friday(made 3 runs)...and the trans started slipping...cruising was OK but when taking off at a light the RPM's would hit 3000 before the car started moving then it was very sluggish after that if I gave it throttle...on level ground if I take my foot off the brake idling at 1000 RPM's the car doesn't move at all...and it used to...I do have a PTC conv and it's pretty loose but the car has never acted like this...so something is wrong...does this sound like the trans or could it be the conv?...I have another conv to swap in and see if the problem still exists but before I do that is there anything else I can do to determine whether it trans or conv?...also I did check the TV cable...didn't re-adjust it but it looked like it was in the same spot(number of ridges showing are same as always)...
