I do not believe all trans shops are crooks. Typically a few bad apples have put a taint on the industry.B&N Transmission in Ottawa, Ontario, Canada is owned and operated by one of the nicest families that I can think of and have tech's who are very knowledgeable and very competent.
Is not the CD4E a Mazda design.. made in the USA by Ford?Doesn't matter anyway, there are problems with it, so, I would assume hopefully the engineers have improved its durability.
The Taurus AXOD was, I believe a GM design used/abused by Ford.Piece of crap until the internal plumbing was augmented.
