Vehicle is a '91 300-SEL. Research on this site indicates I have a 722.3 transmission.
On another WEB site I've read all sorts of horror stories about B2 pistons failing in
early 80's thru early 90's 722.3 transmissions.

- Is this device accessible after removing
trans pan?
- If fluid and filter are change annually &
car is driven in a sane fashion, what is
the likelyhood of failure?

Thanks for your time.
