code list ?
does anyone know where i can see a code list or does anyone know what these codes mean and how to fix the problem. my truck has been running fine until about 2 weeks ago. i would take off from a stop sign shift to 2nd and then it wouldnt shift to 3rd. i had to pull over, it just kept reving high, started again and the same thing,so i pull over again and turn the truck off, re-start and go again and it shifted fine. or sometimes if i stop and then punch it, it would shift hard . i pulled the codes last night with my tuner and here they are.

603 is common and usually ignored when you have a tuner or chip, It can be a real issue but most often it is just the tuner.
733 - caused when the engine RPM drop is not detected when the PCM commands the shift.
Damaged Connector/Wiring Short, Damaged Shift Solenoid Assembly, Damaged PCM (Now the 603 is looking more like a real code instaed of just a tuner thing). To start check all of the wiring.

In the past, whenever that's happened to my posts, what I've written never see's the light of day. I have no clue what I'm doing wrong, but whatever it is, the posts never show up.
That being said, I have several code sheets saved to MS Word doc's and Adobe .pdf files I'd be happy to send to you, if you want them.
