I'm seeking insight into how the following tables under 4L60E line pressure parameters affect transmission operation in $0D:

Pressure ramp delay time vs tps vs shift (sec)
Extended ramping pressure time vs tps vs shift (sec)
Initial ramping pressure vs tps vs shift (psi/sec)
Ramping pressure vs tps vs shift (psi/sec)
Post shift ramp time vs tps vs shift (sec)

In the stock bin for my 1995 K1500, these tables are mostly unpopulated. There are some negative values (psi/sec) in the ramping pressure vs tps vs shift for the 1-2 shift. There is also a 0.5 second value in the corresponding cells in the pressure ramp delay time vs tps vs shift.

I assume these tables modify line pressure during the line pressure modulation time during an upshift, but don't understand exactly how they function. I'd appreciate any guidance.
