| >IS there any adjustment required when installing a new vacuum modulator?
| Usually. But if it shift fine with respect to hashness/smoothness of the
| shifts when installed, then, no.
I never had a vacuum modulator when i purchased the car 2 years ago, it was
plugged off and perrished, the shifts were harsh.
Ive totaly restored the car externaly, also removing the engine and trans
stripping and rebuilding, also rebuildign the front end etc.
the new modulators stock calibration gives little to no hydraulic pressure,
one has to drive like a grandmother. disconnecting the vacuum line, ie, full
pressure, gives neck snapping gear shifts. I Thought there would be
something to adjust ;)
