I am replacing the flexplate in a 2004 F-150 Supercab 5.4L 4WD. Does any one know the secret for getting to and removing the two transmission-to-engine bolts on the top of the transmission??

Long extension over the top of the trans? Is there any access with a wrench from the top?

 

Lower the transmission and use a long extension with a swivel socket.

 

By "lower the transmission" - do you mean remove the crossmember and lower the rear end of the transmission a little to make more room on top?

Yes.
The cross member should have been removed by now.
It has to come out to replace the flex plate.

 

The crossmember is removed but I was afraid to lower the trasmission. I didn't know how far I could go and didn't want to risk damage to the motor mounts without asking the best way to get those bolts out. Besides - this trick is not in the Ford manual . . .

So would this be the correct procedure (starting with all transmission-to-engine bolts installed:

1. Lower the rear end of the transmission and remove the upper bolts. How much can I lower it?
2. Raise the transmission and remove the remainder of the bolts.
3. Remove transmission and replace flex plate.
4. Install transmission - lower bolts.
5. Lower the rear end of the transmission and install/torque the upper bolts.
6. Torque the remaining lower bolts

Thanks -
