how do I identify a diesel zf5?

[fuzzydog]

Looks like I'm shopping for a new (used) zf5 for my 91 F250 7.3

I've seen some advertised but is there anything (numbers?) on the outside of the trans that identifies whether it is a gasser or diesel? and is there a site to check out the numbers?

I don't want to go to the trouble of putting in a trans just to find out someone sold me a gasser trans.....I could end up in jail.....

gasser trans won't bolt up to a diesel, different bolt patterns

The diesel trans doesn't have starter boltholes on the bellhousing.

^^^Thats probably the easiest way to tell them apart. They also have a large cut out at the bottom of the bell housing that is closed off by a bolt on sheet metal access cover. All gasser bellhousings have one solid face of mating surface all the way around.

Once you look for those two details, they are very easy to spot.

The 460 bellhousings have the same cutout on the bottom, it's only the small block stuff that has the flat mounting face.

The E4OD that I got was originally from a 460 and it didn't have the cutout (had to replace the case to use behind my diesel). Maybe they did things differently on the ZF?

Entirely possible, I know the 4 speeds and C6 use the same cover setup, haven't been under an E4OD truck though

thanks everyone - seems like this would be the most obvious way to confirm.

I found this on the ZF web site. The second column shows Zf part numbers that will fit behind a diesel.
