Ok I'm still dealing with the same issue as a year ago. I need a used tranny for my SEC. I've had a hard time locating one. I was told that a 380 or 560
SE/SEL/SEC would fit my car. Is this correct? I was also told that the part#s
must also match. What is the part# for my tranny. I located 380 and 560
trannys at Potomac German Auto but I want to make sure its ok to put either
of these in my car. Also would I have to convert the torque convertor as well or would my current one be ok. My current tranny refuses to shift out of low gear. It goes into reverse, neutral and low only. No warning or symptoms it just showed up as I pulled off the highway and turned the motor off one day. Someone please help me put this issue to an end. I will probably be selling this car once I get the tranny in.
