Transmission Help

I need some help identifying the transmission in my 66 ford f100. I have the 300 Straight 6 and a 4 speed on the floor.

I hope those of you that are at slick stock are having a great time.

NP435 was 1-ton and up, 1/2 ton and 3/4 ton had T18. At least my two half tons are T18's.

The '78 3/4 ton I scrapped a few years ago and the one ton I scrapped last year had NP435's which I have found is a lot more common here in Ok than T-18's or T-19's. All the 4 speed slick's I have ran accross have been T-98's ('61-'64) or NP435's ('65-'66). Tom

In 1966, there were 2 optional 4 speeds for F 100 and F 250 , the T18 was the regular duty 4 speed and the NP 435 was the heavy duty 4 speed.The F 350 series did not offer the T 18.

Tom got it right
actually it was the t98 not the t18 61-64
they started using the t18 in 65.
