I have an 82 f-100 with the 300. I'm pretty sure my transmission is finally gone. What would be some options for a new transmission?
I know that some have 5 speeds, but are there any 5 speeds that don't need the computer?


TIA

 

I don't think any of the 5 speeds have a Computer. Don't quote me on that. But you have the option of the Mazda M5OD and ZF 5 speeds. The ZF is the toughest of the two and most sought after. With the swap from any 4sp you will have to change the hydrolic setup. The 5sp have internal slave cylinders. Drive shafts will be different and will have to relocate transmission cross member. Other than that they are basically bolt in sway. Clutches will be different from a 4sp too. I did the M5OD swap in my truck from a SRod 4sp. Had to have a shorter rear shaft and longer front shaft. I used my crossmember and just drilled new holes. New clutch and swapped slave cylinders. Was a big upgrade from the SRod. Better gas milage and all around drivability.

 

Yeps, the ZF is a very strong and desireable trans. Ford put in it in F450's. I've seen it in tow trucks. It has a granny first for towing, and the .76 (IIRC) overdrive. You can do a search or google it, and you'll find some good write ups on the swap.

The 4X models run about $600-$1200, depending on condition, mileage, rebuilt status, etc. The 2X 's are a different story. I've seen them listed on Craig's list for around $300.

Here is a photo of everything you'll need to do the swap.

 

make sure to get the crossmember with the 5 spd, if not, you'll have to make something, as the 5 spd sits higer than the other transmissions. you can see that in the photo that Kevin posted

 

ZF FTW! It's a crusher. Drives like an old three-on-a-tree around town. Might as well be a three-on-a-tree what with the long shift throw and all. It isn't made for slapping through the gears between stoplights, it's made to work. It's got a low reverse gear too; a wee bit higher than the 5.72:1 (or 5.27:1? been a while since I looked...) first, I think, but still pretty creepy.

The only thing that keeps it from being a one day job is having to measure between the yokes before you schlep the axles off to the shop. Double Cardin in the back keeps the angle from being too much of a worry unless you lift the truck.

For me it was all about the OD. Cruising rpm = 80-85 mph now vs. 65-70 before - and 70 mph on an Interstate gets you run over and dog-cussed here in Texas.

 

Of course you'd need a new, good-quality clutch set, throw-out bearing/slave, and carrier bearing along with everything else, too...

Don't you mean 'drive shaft(s)'?

 

Sho 'nuff, meant to say the drive shafts. Long week at the office...
