3 speed gear ratios
i have a 1966 F250 with a three speed manual transmission. The transmission code appears to be 3K4 while the tranny body code is C (or G) 5AR 7006 B. there is also a DIF stamped not far away from these other codes and a capital F in between these two.
does anyone know what the gear ratio is for this transmission?
thanks

tripleframe, thanks for the reply. do you know what the name is for this transmission i have? i saw elsewhere that these were called "top loaders" but i thought only the 4 speed trannies were the real top loaders. do you have a spec sheet you can refer me to where you got those ratios from? many thanks for sending over that info!!

The 3 speed is called a 3.03 top loader. They are very similar to the 4 speed top loader with only 3 forward gears. There should be a model number stamped into the trans. This would get you the exact information for your trans. This is where I bought the rebuild kit for mine. 3 Speed Trans (RAT/RAN/HEF) - Toms Bronco Parts
