Pressure gauge question. . .

[JR1964]

When reading pressures, is it normal for the needle be fluctuating rapidly about 20ftlbs, say 80-100 at
idle in park, or should it be firm on 90?

I'll post back pressure readings in all gears, along with some more questions, but
wanted to be sure gauge was acting normal or not.


Thanks,

Pressure guage fluctuations

I would love to know the answer to this.

Does a jumpy or fluctuating pressure guage needle indicate a problem?
