When I'm out shopping for a 4T60, how can I spot the difference between it and a 4T60E? Also, what are the clues as to if it may be a 4T60HD?

4T60 has a 5 pin weatherpack connector on it.

4T60E has a 7 pin metripack 'round' connector on it

Sorry I didn't have a 5 pin weatherpack connector but the 4 pin connector show is a weatherpack connector. The two to the right are the 7 pin metripack connectors.

Very nice! Does the trans have any external markings like 4T60 on it?

The 4T60 will have a connection for a TV cable, while the 4T60E will not.
Note that they BOTH have vacuum modulators.

In 85 to 90 there were models of the 4T60 that had the 4 pin weatherpack connector as well as versions with the 5 pin weather pack connector. By 88 they were all using the 5 pin weatherpack connector.

This true no matter how many pin connectors it has?

Should be. The "E" version has no need for the TV cable as all the shift points are controlled by the PCM.

Saw that the pre 88 trans only uses three out of the 4 pins. The 88 trans has 5 pins and appears to use all 5. What are the other theory used for. The diagrams are too poor resolution for me to read it. Just trying to decide if I should look for the later trans. Plan on upgrading ECM.

There are several wiring variations:
One 4 Pin version uses 2 wires: +12V to the TCC with the TCC being internally grounded. Then another wire to the 4th gear pressure switch.
One 4 Pin version uses 3 wires: and has the 3rd gear pressure switch wired in series to the TCC and a ground. The 3rd wire goes to the 4th gear pressure switch.
One 4 Pin version uses 4 wires: 2 for the TCC, 1 for the 3rd gear switch, 1 for the 4th gear switch.

One 5 Pin version uses 4 wires: 2 for the TCC, 1 for the 3rd gear switch, 1 for the 4th gear switch.
One 5 Pin version uses 5 wires: 2 for the TCC, 1 for the 3rd gear switch, 1 for the 4th gear switch, one for the fluid temp.
One 5 Pin version uses 5 wires: 2 for the TCC, 1, for the 2nd gear pressure switch, 1 for the 3rd gear switch, 1 for the 4th gear switch, one for the fluid temp.

While going through the manual again, I noticed that the 4 Pin connector was used up through 90, only 1991 was all 5 pin .
