No such TRANS code of 6 for F100's. It's either a C or a G.
C = Ford Type 3.03 3 Speed Manual all Syncromesh Transmission.
G = MX Cruise-O-Matic.
17 = Ford 9" Rear Axle / 3.25-1 / non Limited Slip / 3,300 lb. Rear Axle Capacity.
5,000 lbs. Gross Vehicle Weight Rating.
172 net HP @ 4,000 RPM.
24 = Jacksonville FL Ford District Sales Office, where the original selling dealer ordered the truck from.

You were mis-informed, it is not a large truck trans.
i know at 60 mph the motor it at a high rpm and according to rear end plate it has 350 gears tag # wdm-m 3 50 6 b 301 i just thought since its a large ruck trans the gears ratio is different from a medium truck trans
TRANS code 6 is a Spicer 5 Speed Direct Manual Transmission only available in F750 and larger trucks.
The smallest large truck that was available with an A/T were F750's which came with Trans-Matic's.
There is no way your F100 has a Trans-Matic. You would have to cut a huge hole in the floor pan for its trans case to fit.
The Warranty Plate that the TRANS code is located on is prolly corroded, making the 6 appear as a G.
The axle ratio has been changed if it has 3.50's. The AXLE code for an F100 with a 9 inch with a 3.50-1 ratio is 08.
