Check for fluid in the modulator line at the modulator if you pull the
line from the
modulator and it has fluid in it then it's bad. If you have no fluid there
then check
the modulator line for full engine vacuum at the transmission and
response. You'll
need a vacuum gauge to check it. If you have engine vacuum the
transmission end of the
line then you will need to snap the throttle to see if the vacuum gauge
responds as it
would if it was hooked directly to the engine. If you're unsure of what I
mean then
hook the vacuum gauge to an intake vacuum source a snap the thorttle open
quickly to
see what the gauge does when you do that. For the most part you should get
the same
response at the line where it goes on the modulator. The last thing I know
of too look
at without too much disassembly is the governor. It may be sticking and
not allowing
an up ****ft to occur. If you can hold it full throttle in low gear and
****ft the
****fter to second gear at above about 4500 rpms and the transmission up
****ft the
governor is probably ok.
