The transmission I am referring as having a tendency for early failure is the automatic 5-speed, which was available as an extra cost option in most markets, except the U.S.
This transmission was also available to the sedan and the wagon but ONLY on 6-cyl. gasoline engines (4-cyl. and all diesels only could be ordered with the 4-speed automatic as an extra cost option, -the 6-cyl. version could be ordered with either-).
The 5-speed automatic felt much quicker than the 4-speed automatic since it always started from standstill in first gear instead of second.
As I understand, the 5-speed manual transmission did not give any major problems, beside its long throw between gears and the heavy clutch the owners have to live with.
