Fred:
I don't have any profound insight into this but I do have a question to
help me puzzle over it. Isn't it true that the Moss box in the +4 is not
directly mated to the engine but is located between two prop shafts on
the chassis? I have a good friend who is very slowly restoring his +4
dhc and that's the arrangement on his car. His is a later model, but
I'm not sure of the exact year, many years after yours. Id have a
hard time thinking that that heat derived from the engine, but was generated
within
the box itself. It strikes me as excessive, but I'm very interested in
what other +4 owners might say.
Mercifully, we 4/4 owners have our trannys directly attached to the
engines, and the whole d**n car gets hot, so I've never bothered with the
temp of the tranny itself ;-)
Cheers,
Will Zehring
