I have recently purchased a 1994 f-superduty (f-450 to some) dump truck. It is currently an automatic which i cannot stand. Im looking to convert it to a zf5. My question is will my driveline parking brake from the automatic bolt up to a zf5? Also if im not mistaken they used a 4x4 zf5 in the super duty correct?

 

The F-SUPERDUTY uses a 4x4 trans so yes a ZF-5 4x4 will bolt right up to the brake adapter.

 

If youre swapping anyway, and dont mind a little extra work, a zf 6 might be even better.

 

Thanks for the info guys. Also im not against the zf6 swap but how much more work will it be to install and is it beneficial?

 

what seems to be wrong with the E40D?

 

No PTO ports and i want a stick lol, other than that the transmission is fine. I would keep it as back up.

 

The 6spd, has another lower gear to help you get rolling, but it will not be a direct swap,like the ZF5 will be. The drive line park brake from the E4OD will not fit the 6 spd., as the output shaft is larger on the ZF6. It is also taller so you will have to modify the tranny floor cover to get it to fit. Not worth the extra effort in my opinion.

 

Ya zf6 isnt a bad idea but not really worth it. Plus i dont want to make a custom parking brake. The zf5 has a low enough first anyway.

 

the E40D is rated to tow more than the ZF5 and is a fairly expensive transmission.it also sports a slightly higher OD gear which will prove helpful for economy with the low gears in the rear axle.at around 35mph,you have a direct connection like a manual anyway.
you can swap in a 1356 t-case with a PTO.
you may just want to run the truck for a while.maybe the auto thing will grow on ya.
swapping out a perfectly fine E40D for a ZF5 would be a downgrade imho.it's one thing if the truck isn't worth the $ for a new/rebuilt E40D when one fails,to just swap in a ZF5 because it can be much cheaper,but id never do such a thing with a good E40D all in working order.
if you ever add a turbo,your boost doesn't drop off between shifts.you keep it.a Zf5 truck can't match the overall performance level of a properly functioning E40D equipped truck.

 

no real benefit of the ZF6 over the 5.

 

I appreciate everyone's input and opinions thanks guys.

 

I forgot the driveline break... oh well. But otherwise, just a tab for the top bellhousing bolts and use the late model 7.3 clutch.
