Rebuild kits, many types there are......
you need to explain what it does good and bad.
does shifting manually always work good?
shifts up ok
down shift bad.
there are 2 devices that function.
kick down
and
Vacuum modular ( this is load sensing,)
can you down shift car manually with proper action?
the good things are just as important to diagnosis as the bad.
is tranny ever slipping? flares or spin ups?
IS the Kick down cable good and free at both ends and does is move linearlly at both
ends via foot action? (proportional it must be if cable moves and tranny side dont then
the kick valve is bad)
did you look at my page, and at the like to the trouble shooting pdf.?
