Which 5 speed trans ?
I know I've read somewhere maybe not of been this forum but I thought I'd try here 1st. What type of ford 5 speed trans are out there that will mount up behind a 300 six. I have a 82 F100 that I want to put a 5 speed in but I'd like to keep the ratio between gears close enough I don't loose a lot of rpm's between shifts. The rear gears in my truck is 2.75.
If you know of such a trans please tell what type it is and if you know the ratio betwween the gears that would be helpful. Also what years the trans might of been available in trucks.

Two choices.
First, do you have a hydraulic clutch? If so, you can convert to the Mazda built "M5OD" trans that was installed in later model F150s. The throwout bearing is tricky, you may need cross member work and driveshaft work.
Or, T5 as in Mustang (V8) trans. 1st will be a bit tall with your gears but you can change those. The OD is taller with that trans. No towing or banging gears, but it will hold up ok. Cross member, adaptor, driveshaft, tailshaft and shifter from S10 model so your shifter is in the right spot.
3rd would the the heavier ZF 5 speed, needs hydraulic clutch, gears are not close as 1st is "granny", 5th OD.

Both the Mazda and ZF have integral bells. To use them, you need the hydraulic set up instead of mechanical linkage.
The T5 uses a separate bell, and will probably bolt up to your bell with an adaptor.

T5 info.
With a 2.75, pulling OD is going to be tough. What trans do you have now?

Currently it has a 3 speed on the column that came in the truck originaly. I have a 4 speed (Code rts or rst don't remeber which came in a 88 F150 I think) and the 4th gear is a O/D. I had planned on trying the O/D trans to see how it would work, but thought if I could put a 5 speed in it and the extra gear might help.
The truck is not on the road yet due to a bad pinion bearing and the brakes are all shot. After I get the rear end back together and brakes , oh yeah and the gas tank replaced, I want to drive it with the 3 speed it has now and see how it does. I don't do much highway driving but would like to have an O/D to help out for when I do. I'm also in the process of putting a fatory tach in it so I'll know about what rpm range I'm in each gear.
