OLDSMOBILE CIERA SENSOR PROBLEM

1996 Oldsmobile Ciera • 251,000 miles

Changed 4T60E transmission and car ran at wot so I unplugged all sensors(tps, maf, egr, and iac) and still had same problem. Had new maf, tps, iac, and egr in it already. Got tps code so changed it out again. No difference. Replaced computer with idenjtical one and no change. Idles very high and will not shift until 35 mph and 50 mph. Changed modulator and no difference. Will tps sensor wires cause rough shift if no signal going to them and does tps need to be set prior to installation
