casey- there is a guy who builds the transmisions for the lightnings that posts in the lightning forum... i believe he has said that the tranny's did change a little bit for '01.
if the gas milage goes down any further on the the lightnings, you'll have to have a tanker truck follow you around.
(i get 10-11 mpg around town, and i drive it every day)
the "clunk" is a defective upper control arm in the '99-'00 lightnings.. ford hasnt come up with a good fix for it yet.
