Could be a bad solenoid or broken band , or valve . Sometimes you can see the broken end of the band if you drop the pan and move things around with a long screw driver . But none of these failures are good to deal with . My pet peeve is US built electric shift automatic transmissions .
Ok ,thanks again mhoward . I will be working on it again hopefully nex week if our weather in better. What part of the country are you located ?I am in Florence SC around 65 to 75 miles from Myrtle Beach .
Thank you mhoward again, looks like you are a handy person to have on this site. I was lucky enough to find one correct key from old owner . Now I need to go about getting a couple more made .
