1995 Ford F Super Duty XL 8 Cyl 7.5L
Transmissions & Drivetrains
when I travel in mountainous areas my transmission will not come out of overdrive to lower gears unless I down shift.
Also the manuel off over drive button on the end of the gear shift at those times does not take it out of over drive. Let the motor home stop for a while and the transmission works fine again for 30 to 50 miles then it does it again.
