Hmmm. I was just about to reply to a recent question (Bruce?) about the
distinction between the 200q and the S4 trannies. It was my understanding
that these are _not_ the same. I believe the S4 introduced a "newly
designed Getrag transmission" (according to material quoted by the S4
Registry website). That they are not the same might be supported by the
difference in relative reliability between the 200q and the '92-'93 S4
versions. Of course, it's conceivable that there is some degree of
interchangability.

So considering that Paul's question was about "S4/200TQ Trans", I'm not
sure if John's answer is relevant to the 200q part. John?
