So I’m looking for help in identifying a manual transmission that I want to use to swap out the C6 in a 77 F150 4x4 with. I have some numbers but not sure how/where to look to see if theyre valid
I don’t want granny gear and was wondering if this one has granny, can I have someone replace the gears so its a 4 speed 4:1
It would be better to post a picture of the tranny from a few different angles. Just the casting numbers aren't going to help much in this situation.
Any idea of what the trans is out of?
If it does have a "granny" low gear, it's doubtful you'd be able to install a "taller" gear set to get rid of the super low first.
You also did not say what motor is going in front of the transmission as that can play into what can be used.
You did say it is a 4x4 how will it be used?
Weekend cruiser to crush paper cups or a mudd bogger?
Any old school trans you find will be 1 to 1, 4th gear, not over drive.
I dont know of any older 4 speed truck trans that dose not have a granny first gear?
What gear ratios are in the axles?

Gotya, I figured not, since theyre so rare
that picture is a 77 150 4wd with a manual reverse shift down not up.

400M is being rebuilt/bored
Its gonna be a weekend trip truck but lifted, divorced and lockers installed
I have a bell housing and adapter for the transfer case , been talking to a guy who has a 4:1 4 speed but he wants 1700 bucks
dont know about the gears, can’t find anything that tells me, I did call Ford to get a build sheet tho
Anybody know about this transmission or whats needed to get it in place on a 4wd 77 150
not sure if its a Ford or Borg but was told there were some used in Ford dump trucks
IMO it's a miserable transmission due to the big gap between 2nd and 3rd. Depending on gearing, and with a 400 in front of it, that might be tolerable. But a 5 speed would be better. That 4 speed OD was never offered in anything beyond an F or E 150. It is not a strong truck transmission, but rather a modified car transmission.

I believe that he said it was an srod, and that it was a tough trans with great bearings.
a few people have told me to stay away from the 5 speeds due to them being too light for the horsepower but my helper said today that there were some that could handle it in the F250
If you were doing it, what would you use?
The motor will be making around 500-600hp

I dont remember where reverse was for the SROD but I can tell you the BW T18 & the NP435 have reverse to the right and back to the seat as I have 1 of each for my 81 F100.
I would never use a any of the 3sp+OD transmissions as they are too weak and hard to get parts for.
The M5OD (1988>) is used in F250 trucks with 351's just watch as the later ones dont have speedo cable holes.

Is the transfer case "divorced"? If so then you are looking for a 4x2 transmission.
But then you say "adapter for the transfer case"?
I know the T18 & NP435 dont shift fast as they are a truck transmission and the gap between 2 & 3 a little big but they are strong and you can get parts for them. Unless you need the garnny first for heavy loads you drive them as 3sp transmissions.
If you want over drive with the T18 / NP435 look at Gear Vender's unit and you might be able to split 2nd gear before shifting to 3rd direct.
I do that with my NP435 and Advance Adapder's Range Spliter.

It is not divorced yet but I want to do that.
Its gonna be a complete restoration project so I have time
I’m almost done with my Daughters 78 F250 so I’m trying to gather good information while the motors is going through the shop and be ready as the weather allows
I found a 435 4 speed thats maybe worth using
400 bucks
