1972 F100 4spd new process 435Posted by Keith _Md on October 22, 2002 at 13:12:45 from (63.118.38.222):
The question I have about this transmisson is can a over drive gear be added? in its original state this ia a creeper first and reverse transmisson, so under normal driving you only use three of the four forward gears. The problem I have is when I am on the highway, just to do 60 MPH I feel like the truck is turning high RPM's to acheive this speed and an over drive gear could eliminate this. My dad told me it might be possible to add a gear to it, but I need some expert advice on this. Thanks for any info. Keith
