Re: 700r transmission hard and late shifting
That missing spring is your problem.
The springs act against those little levers with centifugal force as it spins
in the transmission.
This controls shift timing and firmness.
Look to B&M, they offer a shift improver kit
that replaces those levers and springs. The
kit comes with an assortment of different weight levers and heavy and
light springs. Its sort of a trial and error thing selecting the components
but easy to do.
Download the instructions from B&M, you'll understand.
