<VV> Smoke signals

[Frank DuVal]

Harry's right on the quick check.

If there is a hole in the diaphragm, then yes, it has to be replaced to 
prevent sucking ATF into the engine and burning it, and the money in 
your wallet! ggg

One could disconnect and plug the hose, but the tranny will shift 
harshly and probably eventually do internal damage. It is OK to do this 
for further testing to see if the smoke clears. It may take a while to 
burn out the existing ATF in the hose.

One can also use a Mighty Vac type tester and see if the modulator holds 
vacuum.
