Transmission problem
1991 Acura Legend 6 cyl Front Wheel Drive Automatic

I recently had engine work done> I had a head job, and all new gaskets. When I got the motor put back inI used the same transmissin. I had no prior transmissin issues. After the motor was reinstalled, and it was started the overdrive light and the check engine light were on. The engine runs well and smooth, but thepower isnt there. What could possibly be wrong. I have a repair manual but it says nothing about the flashing overdrive light.

Hi legend35,

When the CEL and D4 light starts flashing, an error has been detected and you need to retrieve the trouble codes to find out what is wrong.

Most probably a sensor has not been plugged in correctly. Is the speedometer working?

Bridge the SCS (diagnostic/test ) connector and count the flashing codes both for the CEL and D4 to find out what trouble codes are reorded.
