I assume you tried manual 1 & 2 using the shift lever, and checked the fluid level in Park.
My shop manual (early 99) lists a PO781 and a PO783 as solenoids and other internal components and a flashing OD light. I don't see a 782 in my manual, but it's almost 10 years old.

I also found this in my manual. No forward and no reverse gives no electrical causes, and the hydraulic/mechanical routine #307 says check fluid level and converter drain back valve. It says inspect valve and perform a drain back test. If the main pump seal went, I think you should be leaking fluid?

Crawl under the truck and find the tranny, and first look at the drivers side where the shift linkage bolts to the tranny case. There's an electrical plug hooking into the switch there that sends gear selection info to the PCM. On the passenger side, up high where it's hard to see, is the main harness to the tranny. That connector is an upside down cup that will hold water if any gets in there and cause shifting problems. I know this because it's happened to me.
