2001 Ford F250 -7.3L Powerstroke - any good?

Have my eye on a 2001 F250 extended cab longbox. Fully loaded with automatic. Looks like it never pulled anything - no 5th wheel hitch or anything, just a small receiver hitch. Truck has 112,000 miles (180,000 km). It looks mint - inside and out. NOt a scratch on it.

Is there anything in particular to watch out for in regards to mechanical issues with this particular model year?

I realize that by now, the good ole' 7.3 powerstroke diesel is pretty much bullet proof, but what about the automatic trannies? The older automatics had so many updates it was hard to keep track.

Anything to be cautious of?? Any help is greatly appreciated...

I have owned my 01 for about a little more than a year now and have had very few problems. I bought mine with 125000 miles on it. I have replaced the CPS sensor and the most recent was the front tranny seal. Thats it! I do have an intake, exhaust,and a DP tuner on it.

Have a dealer run an OASIS report on it. That will show you if any warranty work was performed on the truck. As for the '01 model year, the only knock was the 4R100 had a mechanical diode that was prone to failure. Only year (partial year run if I remember right) it had this in the tranny before Ford changed it back to it's original design.

Pardon my ingnorance, but what is the CPS sensor?

Did the mechanical diode cause major failure, or was this just a small annoyance that ruined driveablility?

Ahh.....answered one of my own questions......Camshaft Posistion Sensor. Will look into that with dealer and ensure it gets done.

Was exhaust modification a big improvement? What about a chip??

When the diode fails, it will not allow the tranny to shift either into 2nd or 3rd gear. It will not "unfix" itself either. Once it goes, it's toast. Total rebuild is in order. If it did go in the past, chances are the PO took it to a dealer for a fix, that's the reason I recommended an OASIS report first to see if the tranny was rebuilt. If it was rebuilt by the dealer, they would (should) have done away with the mech. diode and given you the non-diode version in the truck as a replacement. It was not a recall but a Tech Service Bulletin (TSB) on this issue.

A popular exhaust upgrade is to go with an aftermarket 4" turbo back system from one of the sponsors here on TDS. A very popular chip/tuner upgrade is the DP Tuner. But, I strongly recommend before any performance mods are done, install a quality set of gauges on the truck. EGT, boost and Tranny temp will be the ticket.
