TRANS SWAP

Hey hey. Im thinking about some mods I would like to do to my truck, the main one is to get rid of my auto trans. I know its a big project requiring lots of time and money. So from what I am aware of, not being able to find much on the topic, the manual trans from a 1997 Ford F350 4x4 is a ZF5. So if i sit and think of what I need to do it i can come up with:
-Manual trans
-Clutch pedal assembly (now is this just an extra pedal or was there 2 dif. ones, one for 2 pedals one for 3)
-Clutch master cylender
-Lines to the trans
-and the mounts? from a truck that had this trans.

I am piss scared of trans work, mostly because I have never done anything to a trans/ with a trans. So with that said, can anyone tell me what im missing or overlooking here. Is there any type of computer junk or something like that. I was told that if i convert to stick it wont need any computer stuff. also can I put a trans cooler on a manual trans, may be a stupid question, but like i said i have never messed with transmissions before.

-Thanks in advance for your help, you guys rock.

You'll need a new PCM(computer) out of a manual transmission truck.

Really not that hard of a swap.


I'm gettin ready to do the same thing in my truck. Swap a manual in that is.

If your going to do this. Why not look at getting the 6 speed.

Don't forget you will need a new flywheel.

Good call, about the flywheel, i saw something while researching the topic on google. On a cummins forum there was a guy who swapped a 12 valve cummins into an OBS ford, he also put in a manual trans, It didnt have too much about which trans to use or anything but it said something about dual and single mass flywheels, what is that? He also stated that due to the fact that he put a 12 valve in his truck which doesnt require a computer, he opted to swap the trans to manual since a stand alone computer for an E4OD was required and it has an $1600 price tag whereas the manual trans doesnt require any type of computer. Im not questioning your knowledge or trying to start something, but what is the reason for the new pcm. As previously stated I know little to nothing about transmissions. Also, what years did the 6 speed come out of, i have only seen a 5 speed in an OBS.

On a '97 automatic the PCM controls the engine and transmission. If you eliminate the transmission, the PCM is going to throw a fit. One a manual '97 the PCM is only programmed to run the engine. It doesn't care what happens behind the flywheel. So to answer your question, it doesn't have to do with your new transmission, it has to do with your computer controlled engine.

The guy with the Cummins you mentioned had a non computer controlled engine, so he didn't need anything at all.
