P1773 02' Honda Civic LX 1.7 auto. Keep getting the same code p1773 after every half hour of driving the CEL comes on a D light flashes. Won't shift gears, very dangerous! Please help me! I Changed CPC solenoid twice, (6 Continuity), alternator, belts, alternator includes Voltage reg., ELD, battery tests fine, and checked all wiring. ECU??

Trans is probably dead

That was my original thought, but it seems to shift fine. The battery light also has an occasional Flicker and when I seen it flicker I knew the car would mess up. I turned the idle up by unplugging a sensor, it fixed the battery light but the Transmission still throws a code after about 30 minutes of driving... Also, I read p1773 has to be electrical and can't be mechanical. When I put the aftermarket solenoids in, it did rev up before shifting. Other than that, it seems to shift fine? Thanks, Jeremy

also, one known issue that fries ECU's is loose alternator bolts - check them

Solved!!!
wasn't the ECU or transmission. Turns out my problem was due to buying an aftermarket AC clutch compressor. Problem has a disappeared ever since I disconnected the relay.
in addition to having problems with shifting it was also pushing radiator fluid out of the overflow tank. That has stopped as well.

Keep a close eye on that. Common sign of head gasket failure.

yes, I read that and I will. I was about to buy one and replace it. 145 PSI all four cylinders water pump is running and passed the carbon dioxide test as well.
