Yes the mechanic ran the codes. While I am not certain what they were, he and the transmission shop he uses confirmed the diagnosis of a bad transaxle. Lower estimate was replacement of valve body and solenoids.Highest was for new trans and install Also the error codes could not be cleared so I can't pass NY State inspection. Hopefully a warrantied (1 yr min) used trans can be found. If not I will have to donate the car.
Thanks for the suggestion though. Much appreciated.
