7747 Shift Points

[Ken Kelly]

Jeremy,
	How about telling us the application. I agree with other
responses. The 4L60E was introduced after the 747 was
discontinued. The 747 on a chevy v8 (305) should be paired
with a 700-R4 or a 200- 4R. The 747 does have TCC control
for these applications. If the TCC stays locked I would
assume the shift is hard, also damaging.

	I know that in the F-body the 4L60E was introduced in 1994
and used the 8051 PCM.
