My truck is a 57 with the stock 272 in it, I would like to find an automatic that will bolt up to the original motor. which one will fit?


Thanks, Derek

 

The 57 has the Ford-o-matic (FM) tranny. This would be a direct bolt on. In 59 they came out with the Cruise-o-matic (CM) tranny. The 272 was gone by 59, replaced by the 292. The FM tranny has a one piece case like a later C6. The CM has a 2 piece case ( separate bellhousing) You should be able to use either one if you can find one. I'd look for a parts truck so you could grab all the pieces needed to swap it over to a automatic. You could also look around and see if anyone makes a adapter kit to bolt a later C4 or C6 tranny to your Y block.

What Automatic Trans will work on 292 y-block?

Fordomatic, Mercomatic and Cruisomatic were built for Y's, 1954-64.
Parts and repairs are very pricey.
The Ford-O-Matic bellhousing for trucks differs from the car units. Also, FOM trucks had provisions for water/oil heat exchanger while the '55 cars were merely air cooled. To put an automatic into a truck, you'll need to locate a truck bellhousing for an automatic. Another option is the C4 kit from Flatomatic

http://www.flat-o.com/carproducts/yblock.htm I think most "trucks" with ATs will have the c-6 as it is much beefier than than the c-4.The C4 was available on all but the wildest SBF's in cars, the C6 came with the big blocks.
Light duty trucks with the 240, 300 & 302 had a C4. Ask Gene Benson at FlatoMatic which years he thinks are best. The C4 is the racers choice since it is an extremely effecient design and loses very little HP. Lots of mods available for up to 750 HP in drag applications plus it is cheap to obtain and build semi stock.
The C6 is a dog by comparison. Hey, you're going to need a cross member for that c-4, or something as basic as a tranny X member? <TABLE style="WIDTH: 629pt; BORDER-COLLAPSE: collapse" cellSpacing=0 cellPadding=0 width=838 border=0 x:str><TBODY><TR style="HEIGHT: 12.75pt" height=17><TD style="BORDER-RIGHT: #c1ccd9; BORDER-TOP: #c1ccd9; BORDER-LEFT: #c1ccd9; BORDER-BOTTOM: #c1ccd9; HEIGHT: 12.75pt; BACKGROUND-COLOR: transparent" height=17>C4</TD><TD style="BORDER-RIGHT: #c1ccd9; BORDER-TOP: #c1ccd9; BORDER-LEFT: #c1ccd9; BORDER-BOTTOM: #c1ccd9; BACKGROUND-COLOR: transparent" x:str='Built from 1964 - 1981? 17.18" long overall.

You'll need the truck bellhousing for the ford-o-matic. You can use a car or truck trans though as mine still has the passenger car mounting tabs on the rear of it. If you can find a parts truck, also grab the linkages, steering column, all of the coolant lines running from the motor as those are hard to find. If your not going stock, or it doesn't matter to you, I'd go AOD or c-4 with an adapter. Much less hassle, easier to find parts, work on and locate them and they are better transmissions to boot. -4speed
