need some help

[99ta]

ok the past couple of weeks my GTP has been acting up. it has been missing and bucking at cruise. don't feel it as much during accelleration. I was exploring spark issues, changed plugs and wires and was getting ready to change the coils. well my wife was driving it yesterday and she was slowing dow to make a turn and the car dowshifted real hard and when she went to take off she had to rev it real high to get it to go. 10 miles late the car wont move in any gear. I have had suspision of the tq convertor going bad. would that cause the car not to move at all? it is the tranny? I just had the tranny rebuilt 60k ago. please help as car is sitting in parking lot and I have no clue what to do with it next. thanks!

p0742 is the main code, p0741 set because of the 742.

 

Does the scan tool indicate Yes for TCC release pressure?

 

if no unplug the 20 way connector on the transmission and check again. then let me know. there is a few things it could be.

I don't have access to the scanner. a guys scanned it for me to ge the codes.
