C-6 trans (Are all the same?)
I picked up an 85 E150 with the straight 6 and C-6 trans. I have two spares from a 79 & 75 f 150's. Would there be any reason that these would have any differences or is it all the same?? Thanks

4x2 and 4x4 are obviously different. 4x4's can have two different tailshaft legnths. There's three different bellhousings: small block, big block, and FE. The 75 has no neutral safety switch as it was in the steering column. 79 and 85 probably use a different connector for this switch. The 75 takes Type F while the newer ones use Dexron.
But if they're all physically the same, they'll bolt right in and work.

There is more to transmission differences than just the engine mount pattern, 4x4-v-2x4, and tailshaft length. The internal parts are set up for different torque and HP levels. This is done with varying valve body settings, modulators, varying numbers of clutches, and different size levers and servos. Each engine has it's own particular power curve. A tranny set up for a 351W would not work right behind a 300-6. If you are short on cash take all your cores into a good local transmission shop and trade them towards getting the right transmission rebuilt.

The two spare trannys that I have came from a 79 460 and as 75 460. Are ther any codes on c-6 to determine added info?

There are codes that the big rebuilders know about. Whether they got those from Ford or figured them out with experience is unknown. The transmissions from a 460 would not work with a 300. Try trading...

I should have added the question would I be able to put the pump from the 460 c-6 in. I am preety sure the extremely low speed and massively delayed shift with virtually no reverse means exclusively a bad pump.

Well in case anyone is following this thread, I did a little searching through the local auto recycler Much of what I found out is that the inline 6 has a smaller bell housing and could never be swapped for the 385 series. Apparently they are getting a little more rare at least that is what one yard said I had prices onm used from 450 down to 200 i paid 225 from a yard that only buy's there cars and trucks from the insurance auction usually always wrecks so you know that they were running before the accident much better than the impound auction buyers where most were broke down.

Once a transmission gets to that massive slow shift etc condition they are shot. Clutch packs etc burned up. Again the 460 transmission will not work behind a 300-6. There are still a number of small bell C6 transmissions available. The most common application would be in delivery vans. An AOD would also be an option behind a 300 and would produce better mileage because of the OD.
