[DJQuick992000]

02 7.3l 195000 miles. getting po732, po733, po781, po783 codes from the computer. Curious what these codes mean. Anyone have any info on them?

If you look at the WIKI Technical Articles section on the top BLUE LINE above, you will find a section there for Diagnostic Trouble Codes. It is in there.

# P0731 Gear I Incorrect ratio
# P0732 Gear 2 Incorrect ratio
# P0733 Gear 3 Incorrect ratio
# P0781 1-2 Shift Malfunction
# P0783 3-4 Shift Malfunction

the 732&733 codes are indicating that the transmission is slipping which can be either the torque converter slipping or the transmission internals slipping
781 and 783 are indicators of sticking valves in the valve body or further slippage internally or badly leaking lip seals in the transmission

So what does that mean to you and what do do with this information... it means, most likley, that you'll be in need of a transmission rebuild very quickly and that you should not use your truck for heavy work or take any long trips as you're very likely to get stranded.

There is a realistic possibility that your trans fluid level could be wrong which will give you this type of problem. Keep in mind that the trans fluid level is meant to be checked when the engine is running trans in park. I believe that your dipstick should be marked with levels for hot and cold fluid if there is only one set of marks on the dipstick then it is for hot transmission fluid.
