My 96 accord sedan with 4cyl engine and auto trans had a #7 code read on dash. The green light of drive also comes on flashing. The drive shaft was replaced and came out of trans somewhat and lost trans fluid. With haft replaced in trans, fluid added it ran great but check engine light came on. What's up,?

 

When you short that blue service connector the check engine light will flash a code and the D4 light will flash a code. A long flash =10 and a short flash = 1. Recheck the codes and post the code the check engine light flashes and the D4 codes.

I'm guessing the check engine light code will be 17 and the D4 will be a code 4.
