Sorry to hear about your dad. Mine passed in 1999 so I know how tough it is. He was a pretty fair mechanic and taught me a lot about the way things work on cars and other things.
Anyway, sorry it took so long to get back - life issues.
I was able to test the Throttle Position Sensor after gerry rigging some jumper clips and using a hammer to flatten one side of some 14 ga copper wire to fit in the slots where the connector fits. That allowed me to jumper to a digital multi-meter and read the voltage. Specs call for 0.00v at idle to 4.5v at speed. I got 4.95v-4.96v at all settings. No one had one in stock anywhere within 25 miles of me.I had to mail order it from Advance Auto and got the new sensor yesterday afternoon. I hooked it up and connected my testing equipment. The readings don't make any sense to me. They run from 0.00v to 5.01v. But they just wander all over at idle and as I accelerate. Nothing holds steady until I get to around 2000 rpm where it sits at 5.01v. Bad module? Or another issue with whatever feeds it the info? The idle did, however, drop about 100 rpm from about 750 to 650. According to my Chilton manual, the specs are 450-750. So I guess that's just normal. There was something wrong with sensor I had, so it wasn't wasted money.
I took it out for a test drive of about 6 miles on the parkway and it's still the same. It does not shift into OD. 3,000rpm at 55 and slipping at start up.
The next part in the electronic chain to look at seems to be the Powertrain Control Module. That is not a test, it's just a replacement. After that I see there is supposed to be something under the dash called the Transmission Control Module. AutoZone calls it the Engine Control Computer on their site.
I'm wondering if it's just the torque converter and I'm spinning my wheels?
If you have any more ideas, I'm listening. Thanks. I appreciate the help.
