[Gmecm] 700r4 year

[Jason M.]

Was just going off general memory, it is '87.  looks like 85 would have been 
the spline change.

This page has some good information.

it's roughly 88 or 89 up is the "better" years for 700r4/4L60 transmissions.
More vanes in the pumps and supposedly little design changes that make the
internals stronger.
