I recently thought I had a TPS problem on my '96 JGC, so installed a new one. But that didn't change the 2 - 3 upshift delay problem I was experiencing. So, I measured the voltages. Had 5 volts from the PCM. With both new and old TPS installed, I got .6 volts closed, and 3.9 volts full open. I don't know why I didn't get 4.5 volts as the spec says. I returned the new TPS to the store. My problem turned out to be the Throttle Valve Cable Adjustment. The spec says to precisely align the cable end to the attachment stud but that allowed the cable to have slack in it, I guess from being stretched with time. I adjusted the cable to have a very minor tension at closed throttle, and my shift problem went away. Good luck!
