4 Speed

I just picked up a nice two wheel drive 1980 f-100 today with a 300 six and a four speed and I am unsure as to what transmission it has. It has a synchronized first gear and the shift pattern is:

R-
1 3

2 OD

any help would be appreciated.

I should be one of these.
Tremec 4 Speed Manual RUG & RTS Manual Transmission Part, Rebuild Kits and Overhaul Kits

It's related to the old Ford toploader trannies.

How strong is that transmission compared to a T-18 or NP435?

It's got a Clark 4-speed O.D.

And a comparison...

think of a T-18 as a bulldozer. It's bullet proof.

And the 4 speed O.D. as a whimpering puppy.

....on the other hand, my 4OD has given me 175,000 miles of faithful service. Like they say, the dog is man's best friend!!

"Clark"? The 4 spd ods are not Clark. Tremec for Ford off the old Ford toploader pattern. OD is weak, but someone here has run one behind a 390 for some time.

Yes Tremec SROD…pretty weak and sloppy, however, I liked the OD so rebuilt mine and it’s been trouble free now for 3 years. That’s not to say I wouldn’t look at other options such as a “real” toploader if I came across one.
