I have a 02 Isuzu and went to Chevy today. We had to scan the truck as a 02 Chevy with a DuraMax but atleast it gave up the codes. I don't know if the order of the codes mean anything but its PO733 then PO746. We haven't been noticing the transmission slipping in fact we had been very happy with it, 328,000 miles now. We had a massive rainstorm here in Florida and after we had left the toll both it shifted first and second, slipped on the third shift and didn't catch. After that it locked us out of reverse and only will run first and second. We checked fliud level and unpluged all the wire connectors with no change. If a solenoid is sticking would it be safe to asume we can replace it and it could solve the gear ratio error too. I also read here that someone left thier truck in water for 10 min and messd up the linkage positioner and reported similar codes and issues and then there is that NSTB too?
