1999 expedition AWD automatic transmission. Transmission is popping only when under a load to accelerate or pass. Makes a whining noise while in reverse but hits all of the gears and shifts fine. There are no warning lights (check engine, ABS) on and push button OD works fine. Fluid level is good and I recently changed out fluid and filter but with no improvement. So, i dont have a clue?????

Have you ever changed the transmission fluid flush and replaced the transmission filter?

replace the torque converter or try to get the transmission flushed first by a professional auto trans outfit

SOURCE: 1999 F250 only goes in reverse, no forward gears.

I believe that reverse is operated by a brake band. So it seems to be stuck. It is operated by a piston, and the seal could have swelled and caused too much friction. But you could loosen up the adjustor so that it is disengaged, in order to get forward gears again. Perhaps you can force the piston to retract as well, once you drop the pan again.

SOURCE: I have a 1966 Ford Falcon with a C4 transmission.

I would begin by replacing the filter if its not new, 2 possibility of issue, faulty shifting module or defective transmission rebuilt. just because it has been rebuilt does not mean the individual work on it did a good job. the less cost effective way is to locate used modulator from ebay or junk yard, if that does not rectified the issue than more likely it will be the tranny. the bad part is that I dont know of a company offer a bench test for the tranny modulator.

on the bottom of the transmission pan you will find a nut with a hex or torx in the middle you remove the center plug when the truck is hot and running on a level serface the trans fluod will dribble out if it does not dribble out it is low if it runs out fast a steedy streem it is over full now their is a part that screws into this for a fill if you remove the pan you will see how it works the pan has a pipe/ stack that when full of fluid the top of the pipe is at the full point if you remove the large nut the stack and plug will come out the best way to change the trans fluid is take it to some place that has a fluid exchange equment this will get all the fluid out including the torque converter
