Automatic issues - code 7, no reverse, won't shift

[liquidoblivion]

Blinking D4 light, code 7 is all it gives. It won't shift into reverse and you only get 1st gear in D4 or D3, you can manually shift to 2nd, but thats it. I have resistance tested the shift solenoids, tested good, and hot wired them to hear the click, both click, and TCM looks good, no burn marks or busted parts. I have gone through all the troubleshooting guides and nowhere have I found a issue like mine. I am figuring now I just need to swap the tranny but just wanted to see if anybody had any other ideas or suggestions before I do that. I really would like to find out why I am only have a code 7, seems most people when they have issues have a whole list of codes, and it wouldn't seem like any of this would keep it from shifting into reverse. One guide said the TCM isn't even needed for reverse, but then another talked about what solenoid should click when you shift into reverse, and I thought it was the TCM that activated the solenoids. Help!!

7 TPS - throttle position sensor
D4 can blink due to bad VSS as well.

TCM code 7, No CEL, and VSS seems to work just fine

How did you pull a code from your TCM?
You read it off the blinking D4?
This guy says solenoides...

1-Lock-up solenoid 'A' circuit open or shorted.
2-Lock-up solenoid 'B' circuit open or shorted.
3-Throttle Position Sensor circuit open or shorted.

5-Shift Lever Position Switch circuit shorted.
6-Shift Lever Position Switch circuit open.
7-Shift Solenoid 'A' circuit open or shorted.
8-Shift Solenoid 'B' circuit open or shorted.
9-Counter shaft or transmission speed pulse generator open or shorted.
10-Coolant Temperature Sensor open or shorted.
11-Engine RPM (Ignition coil signal) open or shorted.
