1983 300CD

The previous owner replaced the transmission with a new or rebuilt in 1999. I have the receipt from the dealer. He paid $1947 for it. The part number is listed as:

123-270-59-01-88


Checking under the car I found a metal tag on the drivers side of the bell housing with the numbers:

123 270 5901

348658

There is a flat spot on the passenger side just above the oil pan but it is smooth, no numbers. Does not appear to be ground off, but it could be. ??


1. What transmission do I have?

I'm guessing I have a 722.3, maybe a 722.315.




2. What modulator valve should I have?

There is a green one on there now. It leaks. The dealer gave me a black one with a part number A126 270 9179. Shouldn't it be green?
