[Diy_efi] swap part questions

[David Allen]

  When installing a 700R4 in my 1972 Nova, the crossmember had to be moved
back and the driveshaft shortened.  Everything else bolted right up-
shifter, oil cooler lines, speedometer cable, etc.  There was 1/2 inch
clearance between the trans and the tunnel.  But I kept blowing o-rings on
the servo cover on the right side of the transmission.  It would suddenly
start pouring oil profusely out of the servo.  The o-ring would be all
chewed up or almost missing.  After pulling the transmission twice, I
finally determined it would push against the tunnel and press in the servo
cover under hard cornering.  This would ruin the o-ring!  After this, the
Sledge-O-Matic and Jack-O-Matic were brought into play with great vigor and
little restraint on one particular spot on the trans tunnel. Now there is a
funny bulge you can feel through the carpet.  But no more servo cover o-ring
trouble!
  Whatever you do make sure no delicate parts of the transmission will hit
the body when the trans and motor mounts flex. I had 1/2 inch clearence but
that wasn't enough.  There's at least an inch now.  And even though the
o-ring is still intact, there's a mark in the undercoating where the servo
cover has lightly hit the body.
  Just my 2 cents worth!
