did 48 f1s come with a 3spd hd trans in them or is mine a 4spd i never really checked and now the shifter is at one shop and the trans is in the other so i cant check right now without going to get the shifter but my trans has a pto cover on it and i didnt no they put ptos on three speeds maybe i have a four who knows lol

 

I haave a 47 ford that came with a strieght 6 and a 3 on the floor and my father had a 50 with a flat head V-8 and a 3 on the floor. There was also 3 on the tree available. That era was also available with a 4 spd. If HD means heavy duty it is most likely a 4 spd with 1st as a grany gear which was also normal. a lot of people discribe that trany as a 3 spd with a grany gear because normally you would start in second unless there is a heavy load a a need for low end low rpm power.

 

A heavy duty three speed was also available. I ran one in my 49 F-1 after breaking the standard three speed several times. My memory is that it had the 2-3 syncro but square cut gears at least in 1st and reverse.

Note: the 49 was running a 56 Buick nailhead back then-too much for the stock regular duty 3 speed.

 

so what tranny is in my truck because my tranny has a pto cover on it

 

I suspct that you have a 4 speed. I do not remember seeing a pto cover on my heavy duty 3 speed.

 

I don't see any PTO's on any 3-sp's in the parts catalog. Here's a quick way to tell when you are looking at it: left to right, rear bearing retainers for base 3-sp, HD 3-sp, and 4-sp straight-cut gearbox (crashbox).

 

so my tranny isnt a syncrhoed tranny

 

wait but mine is the one all the way to the left

 

None of them are "all" synchro'd. The 3-sp's are synchro'd on 2nd and 3rd only. The 4-sp shown is not at all synchro'd.

I have been told since I posted that HD 3-sp's installed in F-1's used the LD rear retainer, but the middle retainer in F-2's. That retainer allows use of the e-brake on the driveshaft.

 

well i dont have the ebrake on the driveshaft its part of the rear drum

 

What years do the pictures refer to.
My '52 F3 has a 4 spd but does not have the e-brake on the trans.
