My car will not Shift correctly and the D4 Indicator on my dashboard is also on.
Here is what happened:
I hit a deer on my way to work, car was drive-able back home (31.7 Miles)
During the ride home the D4 Indicator on the Dashboard was blinking, so I went 30 MPH the entire way home trying to go as easy as possible on the car and transmission.
The next morning surveying the damage seemed like just the radiator got bent up a little bit as well some obvious body damage.
After fixing up the body, went to drive the car and the D4 Indicator Light was still on as well as the Check Engine Light (Which was on previously).
After some troubleshooting, it was decided to get a replacement transmission, which we got from a local salvage yard (the guy said it was from a working 1999 Civic).
Swapped in new transmission, checked and flushed all fluids, the D4 Indicator was still on.
So more troubleshooting, which two Honda techs said it sounds like it was the ECU (ECM) so I went back to local salvage yard and got the ECU from the exact same car (same part number's)
Got the new ECM installed, and programmed to my car.
D4 Indicator Light still blinking, and car is still not shifting.
Any help please!
