governor pressure solenoid in the transmission is going bad.
Nope. Not in the 93-95 years. They did not have them. 46RH = Hydraulic.
The TPS or IAC can cause weird jerky loss of power sometimes. Those are easy to test and relatively cheap to replace. When I sold my 95 5.2 is had 225k on it and was still going strong on the original motor and trans.
The first thing I would do IF I though it was the transmission is to make sure that the fluid is filled to the correct level. You have to warm it up to operating temp then shift it into N to check the fluid level. Then I would drop the pan and drain the fluid. Put a new filter in and new atf-4 and see if that helps.
To read the codes you cycle the ignition on off on off on then wait for the check engine light to start blinking. That tells you the codes. It may not be the trans at all.
Did you read the link Korea gave you? It tells you how. DO THIS FIRST
Might help you to search as its in the FAQ.. But here:
To display codes cycle the ingition key On-Off-On-Off-On within three seconds. Count the number of flashes, first digit, pause then second digit will be displayed in a series of flashes. (2 flashes, pause, 1 flash = 21)
