c6 difference
i have a 69 f-250 camper special. the original c6 went bad so another was put in used out of a vehicle. is there a difference between a car c6 and a truck c6? i noticed the colum shift was changed over to a cheap floor shift when i tried to put in the colum shift the linkage wouldn't fit it was too short so i was wondering if there is a difference. the internal linkage was messed up as well. i can go to pull and save and buy a used one for 60 bucks. is there a more modern one that would fit a 390. didn't they make a c6 with a locking torque converter or a e4od?

The 390 and all other FE engines have their own bell housing shape that's different than the big block 429/460 and small block 302/351 so your only option is to find one from another 360 or 390 powered truck. I just checked pull and save's website, and they have 3 possible donors, a 73 and two 76s at their yard up in Mead. Be aware that the 76 trucks could have a 400 in them, since Ford stopped using the 390 around the middle of 76. An easy way to tell is to look at the spark plugs, if they all point in the same direction it's a 351M/400 and wont bolt up to your 390.

On my 69 f250 the c6 also has a fixed yoke on the tail shaft, if I don't forget I will look at the linkage and see what it looks like. shouldn't be to hard to do since the motor and trans are sitting in the barn

As noted the FE has a round top bell not shared with any other engine family, you will have to use the round top transmission case, although all the guts can be swapped.

sounds like they put a trans out of a mustang in your truck. mustang had the floor shifter and the shift arm was set to push forward to engage gears where the column shift pushes rearward to engage gears.

OK, I had to hunt for the rod but I did find it. It is 20 inch's long with a threaded adjustment on it. The lever in the picture is in park so when you shift it moves down. Hope this helps and sorry for the big pictures

Mustangs in '67 were available with a 390. The 390 and the 428 CJ was available in the '68 Mustangs so, yes, the C-6 was installed in the Mustangs.

This sounds the most plausible since he said the tranny is in the truck already so it can't be a c6 for anything but an FE.

There's no bell housing with an A/T, it's called a converter housing. The C6 has the converter housing made as part of the transmission case.

There should be an engineering number stamped in to that manual shift lever. Your pic is too blurry to see it. Post what it is and either myself or Bill will tell you what vehicle that shift lever was originally in. In theory, what the tranny is out of. Example would be like C9TP7A256A.

Bill, you might have to do it. Oldest cross reference slide I have here at work is 1984.

The lever arm is interchangeable. Remove the nut, pull off the arm, push on the truck arm, replace nut.
If the truck has a floor shifter then it is likely that someone swapped out the trans or the arm to do so. The trans itself doesn't care whether it is in a truck or a car.
