what would cause it to not engage into drive or reverse? (besides fluid level)
and also what would cause it not to shift into higher gears?

by jumping T and E1? or does the tranny have its own different way?
my O/D indicator isn't flashing though. doesn't it flash when it does indeed have codes?

Loss of fluid pressure internally from a clogged filter, damaged pump, dirt or metal pieces (from other worn parts) making valves stick in the valve body. Slight chance it's electrical (solenoid, wire, ecu) but if the gears won't engage at all it sounds mechanical. Check all the external wiring connections and harnesses for physical damage or disconnected plugs, then test the range switch and solenoids with a DVOM.

The "not shifting into higher gears" thing makes me think dirt or something is making your valve body have fits.

Try changing the fluid and replacing or backflushing the filter screen with brake cleaner. My honda accord was doing the same thing and I changed the fluid 4 times in a row and it became drivable (although it still doesn't like to shift into OD and hesitates for a few seconds). I've been driving it for about a year like that and it hasn't died yet.

well I tried checking for codes as it said on the cygnus guide but I didnt get a single flash. I also checked for engine codes while I was at it and got code 22...
anyways, so I take it its a mechanical issue, not electrical?
I'll try changing the fluid and screen.
has anyone else fixed these problems without swapping the whole tranny?
