<VV> 140 with PG

[Jim Davis]

P&A 30C shows only one Corvair modulator.  The parts book does show a 
different governor and valve body for the 140 hp engine with PowerGlide 
transmissions.  I have rebuilt several 140 PG trans and as far as I have 
seen only the governor and the valve body were different and those parts 
were coated with a slash of Chevy engine block orange paint.

But, when the shift point was raised, they might have found the need for a different "modulation" of the shift, so, indeed they could have used a different modulator. The governor was definitely different on the 140 PG, as I recall. Chevy dabbed them with blue paint, Or some color, I think. Something to remind service folk that they were different.
