ive never changed it. what exactly do i change?

HCCAFan

The fluid and filter in the trans! I have a manual so I can't be of much help as to how you would do yours.

Heater core is very time consuming, I think book rate is 7 or 8 hrs labor.

Change trans fluid and filter...

Step 1: put container under trans pan
Step 2: remove trans pan drain plug (if applicable)
Step 3: Remove trans pan (trans filter will be staring right at you)
Step 4: Clean trans pan and replace filter
Step 5: Replace gasket and reinstall trans pan
Step 6: Put fluid in the trans dipstick tube (should be about 4 quarts)

LUUUUUUUCAAAAS.
Add Lucas Trans Fluid/Service in a bottle. I was not at all convinced until mine started giving me issues. Lucas did the trick.

lucas covered up the problem for now it will come back to haunt you just my words of experience

At 200,000 miles, on an unknown (not cared for) 46RH.......Ill give a kidney to keep it on the road.

You probably have a valid point.
I dont have $2000.00
And on a 1993, I can justify $10.00 for the Lucas.

YMMV

I had a similar problem with my 2004 Jeep Grand Cherokee, where it would back up real slow in Reverse, and when I put it in Drive, it would take about 3 to 4 seconds before it actually went into gear, jerk forward, and then slowly pick up speed, after driving about 1/2 block. When I stopped at a stop light, it would sometimes vibrate, and shut off. I had to shift it to neutral or park, and start it back up. I replaced the Throttle Position Sensor, but that didn't solve the problem. I finally gave in, and took it to the transmission shop, where I have had filter and fluid changes, and other work, done there before. The mechanic drove it, ran some diagnostic tests, and thought it was a solenoid pack that I needed. The cost of that, plus labor, would have run over $1,000; but when he dropped the transmission pan, he saw that one of the 2 filters, in there, had become loose, to the extent, that this was causing all of the problems. Replacement of this filter, transmission fluid, and labor, only came to a little over $200; much to my relief, and smile on my face. Even the Manager was surprised that a loose filter, was the source of the troubles, and that replacing it, solved the problem. Hope this can help someone else, with similar problems.
