I HAVE A 1990 FORETRAVEL CLASS A MOTORHOME (GAS PUSHER) WITH A FORD C6 TRANS WITH NO OVERDRIVE. I HAVE BEEN TOLD THAT GEARVENDOR HAS A DEVICE THAT WILL GIVE ME 3 MORE GEARS. DOES ANYONE KNOW ANYTHING ABOUT THIS?
Gear Vendors have been around for years and they have an excellent reputation. They do build both an under drive and an over drive. It installs between the transmission and the rear end and bacically gives you the same thing as putting in a two speed rear end.
