manual

Just got my 1992 F-350 diesel, traded my 1985 6.9 for it, need manual for 7.3 truck, where do I go. I know nothing about 7.3 motors don't even know if it is a powerstoke or not. Trans shifts hard at start everytime, she keeps shifting in and out of over drive, need help.

The '92 is not a Power Stroke, it's an IDI. You're in the correct forum.
The best manuals are the factory shop manuals from Helm.
The Haynes engine manual is good, but it doesn't cover any other part of the truck.
The Chilton manual isn't quite as good as the Haynes for the engine (IMO), but it covers chassis and electrical stuff that the Haynes manual doesn't cover.
Get the Helm manuals if you can.

The 7.3L IDI is not much different than the 6.9. They are basically the same motor, one is just bored out for bigger pistons (therefore larger Liter displacement). If you are going to overhaul or repair the engine, you will probably want the Haynes book for bolt torque specs. and such since the 7.3 was beefed up a little.

Trans hard shifting could be as simple as the FIPL needing adjustment/replacement.

To set to specs:
With a warm engine and the idle speed set to your engine specs probably 650 in drive (curb idle).

Now with key on engine off. First connect the negative lead of a volt meter to the negative battery post, then place a paperclip straightened to slide up the side of the center wire for a good contact, touch the positive lead to the paperclip. Electrical connector must be connected to the FIPL.

If your FIPL requires resetting loosen the small torx screws and attempt to attain the correct setting. You can loosen the large bolts on the bracket if necessary but try to retain the centering on the FIPL/blade.

Your trying to get closed throttle voltage: 1.1 V, wide open throttle voltage: minimum of 3.8 V but not more than 4.3 V.

If you can attain those #s then tighten the screws/bolts and ensure the voltage is at the correct setting after tightening. You can also do a slow sweep of the fuel lever from idle to WOT to see if there are any blanc (dead) spots, much easier with a really $$$ meter with capture mode. If you still find there are hard shifts or very soft slippery shifts you can adjust to suit your driving.... but be warned slippery shifts will burn the trans up.
