C4 transmission for 77 f150 why don't they have rpm Gage and can we replace add one In to chk the rpm changing in the truck
I hope this is not a
dumb question but why
does the truck not have
an rpm Gage ... I just
installe the vacuum
modulator and I want to
test out the gears
changing when I'm
driving... As I mentioned
the problem I had was
the truck was running
high and not changing
gears that I noticed.
