Absolutely correct. Automatic transmissions DO use clutches (not quite the
same as manuals...but the same principle). Normally, there are anywhere
from 6 - 12 discs within the clutch-pack (depending on make and model).
The convertors also allow for some slippage...especially at initial
acceleration. Automatics also require more attention to maintenance than
manuals since they rely heavily on fluid rather than basic lubrication
(like manuals). I admit though, i've seen and built some very nice
automatics (727, 904, C4, TH350, and TH400's) in my time.
Uhhh...I know i've been guilty of keeping the conversation going...but when
will we ever stop on this subject?
