700r4 Trans

[Kevin Crain]

Consider a few differences in 700R4 design:

'87 and later have an improved valve body and pump design for better
reliability.  

Earlier ones have magnetic VSS senders, later ones have gear-driven speedo
senders which actuate the speedometer which contains a VSS.  '88 was the
conversion year for the Pontiac F-body and Chevy Y-body, whereas '89 was it
for the Chevy F-body.  Go figger.
