<VV> 140 PG swap complete - PG fluid level theory?

[Bill Hubbell]

NO!  ATF expands as it warms up, so do NOT fill it to full mark at rest.  At most, fill it to the "Add" mark, then warm it up and check it again.  If it is just at the "Add" mark then add one pint.  Run it some more and recheck.  

Try to avoid overfilling as that is likely to blow out some seals.

So, fill the PG to "full" then, when it "warms up" the fluid level will
drop, then add more if it drops, keeping it?

This is because running moves the fluid "away" from the dip stick, so the
dip stick registers "more full" than it really is?

I find getting a PG to the correct fluid level is just a little tricky,
since you check the fluid fully warmed up with the engine idling.  Fully
warmed up really means after a drive, I have found it takes several miles.

I'll assume here you don't have that luxury.  With it just sitting you want
to fill it at least to the full mark.  After starting, check it while it's
running and fill so it's showing on the stick, but not all the way up to the
add mark.  The trans needs no "warming" from sitting, you just need enough
fluid in it.

Off the shelf Dexron is fine for our PGs.  Use whatever brand you like.
