ok i pulled tran and completed a rebuild reinstalled trans. only code before rebuild was po700. now i start car eng will not rev above 2100 rpms trans shifts hard and have codes po123 117 108. checked all wiring and cleared code no change.

 

Did you pull the codes with a scanner or in the cluster? The cluster will not display transmission codes.

 

Make sure you're coolant level is good and your MAP sensor is plugged in.

 

ok well i pulled codes both ways. no trans codes. checked all wiring and plugs. now before i rebuilt the trans engine ran great. now i get engine codes po123 118 and 107 and thats before i even start the eng those codes will set . eng bogs with throttle and wont rev past 2100 rpm. temp gage not working either. checked and clean all grounds, computer 40 pin connections. weird all was good before rebuild. three sensors couldnt have went bad at same time. maybe pcm fried? ive built many of these trans never a problem.

 

And you're positive your ECT and MAP sensors are plugged in?
