I own a 90 gs automatic. The other day I was driving on the freeway going about 75mph and simultaneously the transmission shifted down into 3rd gear and the speedometer went dead. Now the s3 lights blinks and CEL is on. I checked the code for the trans and its a code 4. The ecu is code 17. So when i drive the trans doesn't shift into 4th, and my fuel economy has dropped. Any suggestions?
