hello greg, thank you for confirming the differences in valve bodies as i have read they are not interchangeable i didn't know why.
items changed between valve bodies are only those found in the shift kits as i move from one vb
i agree with you as i have 3 different vb
's and 2 different separator plates all of which have been kept together for use later if need be.
i have noticed differences in the galleries within the vb
halves and also the different hole positions and sizes.
yes the gaskets are correct for the 40-3 and all holes are clear (not blocked) as per the visual light test and are not standard.
i will try the cutback spring for bind and install steel ball just in case.
now for the boost regulator,
does the boost regulator work identically in all forward gears if so what could cause a different pressure between them?
what do i look for with its condition?
i know that i have at least 2 different boost regs as the spool valves do not fit the other sleeves.
how can i diagnose boost valve problems?
wow thanks this is getting deep, also i was driving it and at low rpm it would change harder if i held the rpm at say 3000 for a couple seconds then got on it and changed. it sort of felt as if it had to build pressure which didn't show up on the gauge.
what happens when the modulator valve is stuck all the way in so it doesn't move?
