My 95 Ford Explorer will only shift and move in the reverse gear what’s the problem

What is your question?

When shifting the gears it moves in reverse but does not drive forward in the drive gear or the second gear or the first gear sometimes. But sometimes I shift it into the 2nd or 1st gear and it will drive forward then I’ll shift back into drive and it will continue to drive forward. It doesn’t have any leaks, and it does not run hot and it shift just fine but it seems as if the gear doesn’t lock in every time I shift from R to N to D to 2 to 1 the only one it catches while shifting is the R

What makes this problem better or worse?

The more I let it run the less likely it is to go into the appropriate gear
