Hi! The technician rebuilt my 1974 450SL and it is
slipping in final drive [3rd]. He has adjusted modulator
pressure, line pressure etc. exchanged the valve body
with a used one I had as a spare. He has R&I the auto
AGAIN and replaced the 3rd gear clutch packs which
proved fruitless. He is competent but he must be missing
something? The slipping is substantial and I couldn't
live with it. The reason I had it rebuilt was because
it wouldn't go into 3rd [Before that it was SLIPPING
in 3rd]. Please, forum gurus and automatic enthusiasts help
us solve this seemingly impossible to solve problem.
Thanks! Stan M. Brisbane
