91 talon won't go over 30mph/2500 rpms in a forward gear

[91TalonTSSEi]

hey all. I have a 91 talon TSi awd auto. I bought the car in rough shape and have been trying to get it close to drivable. In 1st, 2nd, or Drive the car will move very sluggish. With my foot to the floor i get about 2500 rpms.It has no problems getting to that point, it just wont' go anymore. The car has a supposed rebuilt transmission in it. I have full revs in neutral , dont know if that is important or not. Any idea on where to start? Also pulling codes from TCU and ECU show only constant short beeps....a normal condition correct?


Thanks in advance,

James
