I also have a problem with reverse sometimes not alot maybe once a month where reverse sticks and I have to give it a little rev to kick in. No prob with the other gears just reverse.
If its the 4.0L SOHC then there is a TSB or service action to replace the timing chain tensioner, install an oil restricter in the oil passage and replace the intake gaskets because of a rough idle issue. Once you remove the intake the tensioner and oil passage is accessible. There is a full parts package that includes everything from Ford.
