Tranny Question

Don't know if this is the right area or not.

I have a 1982 Ford F-25 that I am working on turning into a plow truck. I am putting a 300 Inline six in it.

Now the question I have is -

The truck came with a auto tranny. I CAN NOT STAND auto trannys. So I am gonna put a 4 speed in it. The thing that I need to know, is if the 4 speed I have (for 2 wheel drive) will work on the 4 wheel drive truck with a transfer case, or if I need to get a 4 wheel drive tranny and transfer case.

You will need a trans for a 4wd. The output shaft and tailshaft are different between the 2.

If you have a T-18/T-19 the rear bolt pattern is the same for both 2 and 4 wheel drives so you can convert a 2 wheel drive in to a married 4 wheel drive rather easily. If you have a NP435 the rear bolt pattern is different between 2 and 4 wheel drives but you can still use a 2 wheel drive NP435 if you get a transfer case adapter from Novak Adapters. Read the information on the Novak Adapters website, it's very thorough.

How do I tell what tranny I have? I am kind of new to working on trannys, and have only had a ford for about 4 months (I come from a chevy family, But I only have fords now - 3 of them )

If you have a T-18 / T-19 the shifter base unscrews from the transmission top cover, the top cover is cast iron, and the top cover is held by 6 bolts.

If you have a NP435 the shifter base removes by pushing down on it and twisting (like a child-proof medicine bottle), the top cover is aluminum, and the top cover is held by 8 bolts.

If you came from a chevy family you might have a SM465. The shifter base removes by pushing down on it and twisting, the top cover is cast iron, and the top cover is held by 8 bolts. (Good luck getting an SM465 to fit a Ford bellhousing however).

For all the pain you would go through to get a crossmember for the four speed and getting it converted and bolted up to the (probably) BW1345 transfer case, rigging up a clutch pedal and mechanical linkage, and shortening your front driveshaft and lengthening the rear driveshaft and shortening your t-case linkage. If you're just moving snow I would keep the drivetrain that is in it. Even if you do hate auto's. But that's just me. I personally wouldn't go through all the effort just for a plow truck (or an 82 for that matter. No offense though, I don't intend any)

That's ok. The truck does not have a engine or tranny in it. I was gonna put a in line 6 in it, because I have one. I have a 2 wheel drive C6 tranny, and a 4 wheel drive C6 tranny, but the 4 wheel drive one has been out in the weather for about 10 years (It was sitting in the bed of a truck I got for parts - guy said it worked when he took it out) Maybe I will go that way....The one C6 (the good one) is already hooked to a in line six.

BTW - All the trannys I have are for fords....we don't have much in the range of chevy parts, they all got used.

Then what I would try (if it's not too daunting to open up an auto) is to switch the output shaft and tailshaft housing from the 4x4 c6 into the inline 6 c6. Then shazam, you have a 300 with a 4x4 c6 bolted to it.

I still don't want a auto, but I don't want to spend a lot of money either......I have heard a lot about the C6 tranny, but never used one. They are pretty good right?

The C6 is as legendary for strength as the 300 is. Keep in mind, the C6 was the auto used behind all big block engines, and the diesel's, before OD auto's came into being.

Put another way, that a chevy guy can totally relate to. The C6 is Ford's answer to the TH400 that GM offered.

Couldn't take it any longer... every time I see the thread title "Tranny question" I just feel the need to say it...

If she's got an Adam's apple and a wiener, then yeah, she's a tranny...

Sorry, couldn't help it anymore.
