I have a 2000 Ford F450 7.3 4x4 dully with a PTO driven winch 108,000 miles

The truck has develop a transmission slip
I have changed the transmission fluid twice and it drives better but it slips badly
I can drive it up to highway speeds but it has problems getting from 0 to 10 MPH. The transmission runs hotter then normal but nothing major maybe around 205 degrees

Do I need a complete rebuild?

This is a beater truck that I use to tow mainly. It is not worth a major investment. I need the PTO gear and 4x4.

I have several 2000 through 2003 7.3 E350 and E450 short school buses.
Does anyone know if the transmission from these has a PTO gear? I am thinking of pulling the transmission from one of them and swapping it.

It looks like the transfer case just bolts to the back of the transmission; I believe that a 2wd van 7.3 transmission will work with the 2000 F450 setup.

Let me know what you think.

 

any ideas on rebuild costs?

The truck is not nice enough to spend BTS money but Street Smart on ebay has a rebuilt unit with unlimited mileage warranty for $1800.

Has anyone dealt with Street Smart transmission?

This is a 2000 F450 7.3 4x4 dually with PTO

 

The majority of 4R100 transmissions that were manufactures are not PTO compatible. The provisioning required to accommodate a PTO drive is both internal and external. It isn't like you can field convert a non PTO transmission into a PTO transmission... without doing a rebuild using se some different but significant parts.

It is highly doubtful that any of your E-Series short busses have a PTO transmission. I'm not saying it is impossible, just highly improbable. You can easily check this yourself by looking for the PTO access plate on the driver side of each of your busses. If you don't see the cover plate, then it is not a PTO transmission.
