I would pull the pan and check the internal linkage. There is an S hook that attaches to the "rooster comb" that goes to the manual valve, it could have popped off. If not, then your reverse clutches are probably fried

If the internal linkage fell apart, you would be in drive all the time. If you can get neutral then it probably isn't the link. The low/rev and the direct clutches have to apply to go backwards. If you have good 3rd then the low/rev is bad. A test for that will be to see if you have good engine braking in manual low.

Is this in your step side in your other thread?

 

Good time to upgrade to a nice "built" transmission.  Jegs had some for 700-800 bucks that would handle up to 450-500hp.  Perfect amount of HP for that truck!

Wait! Four qts of fluid is minimal in an automatic!  Has this been all drained out including the convertor?  Will take like 13qts I think  or see a manual. Use the dipstick to see if enough is in it. Check in N most times at idle while running. Don't over-fill past the full mark or it foams and causes other problems. If not enough fluid in it to begin, then it won't work right till it is full or at least a minimal qt low.

Have you checked the trans fluid on the dipstick?

Start truck up, put in each gear, put in park and read the level on the dipstick. If its low, add until it hits the full mark. Those transmissions take 9-11 quarts from empty.

4 quarts is a good start. If that is all that is in it keep adding.

Like Poncho says, use the dipstick, don't guess. Adding 1 quart overfull won't hurt anything if you're unsure of your dipstick being the right one.
