1991 Park Avenue 4T60E capacity...

[gregk24]

Does anybody know the ATF capacity of the 4T60E in the 1991 Buick Park Avenue? I am just trying to find out how much new fluid is in there. Its had 1 pan drop (billed for 6 quarts), and two 5 quart extractions. The old fluid was brown, its now dark red. Again, trying to found out what % of the fluid is fresh.

~11.1 quarts total system capacity from new/dry build (including integral cooler) according to FSM.

Can't take credit it for this but use it.

Well never mind because my link doesn't work but somewhere around here someone posted a great excel sheet for this.

By using the previously posted excel spreadsheet and using 5 qts. ATF per change, 85% of the ATF is fresh. Next project.
