Tallyho Posted July 22, 2018 Author Share Posted July 22, 2018 All good info guys! I did a little digging and came up with the info that the 351 had the t18 and the 460 would have had a t19. T18 had a non synchro 1st granny 6.32:1 ratio to compensate for the lack of power for the 351. While the t18 had a synchronized 1st gear of 4:1 which really isn't a granny low. I'm thinking my truck has a t19 because 1st is all but useless for normal driving. While researching this I could out my reverse ratio is 7.44:1 which makes it incredible slow in reverse while plowing lol. I meant that I believe I have a t18...

Gary Lewis Posted July 22, 2018 Share Posted July 22, 2018 I meant that I believe I have a t18... Yes, you should have a T18. As for the 1st gear ratio, don't believe everything you read on the internet. I prefer to believe factory documentation, and I have some on this site that says the CA-spec 460's with a T-19 got 5.11 first gears and the 49-state trucks got 6.32 first gears. Check out the whole of this thread: http://forum.garysgaragemahal.com/No-headaches-6-9-Diesel-td9311i20.html. Or, go through the Powertrains tab on the 1983 Ford Light Trucks Facts Book.

Yes, if you read that thread that's the site that Jonathan sent me to. However, it doesn't fit with Ford's publications, so I believe Ford.
