My check engine light is on and when I come to a stop my rpm drops 500 rpm whi

I think it was p 0770 but not sure. Could this be electrical problem. Seems like the automatic clutch isn't disengaging fully when I come to complete stop. I'm putting car in neutral at stops so trans doesn't wear. Also I have oil leak from cam seals could the oil that's leaking cause the trans problem. Oil is on everything under car. Thanks for your response. God bless

I wouldn't want to speculate. You'll need to get it into a shop to get a good diagnosis. That code is for a shift solenoid, and I cannot see that ever affecting engine RPM. There are certified shops in your area that will give you an honest diagnosis and estimate.

Thank you n aloha...merry Christmas happy new years...

Merry Christmas to you too, Aloha!
