Tranny ATF pump rate at idle???

Post by Chiadog »

Has Anyone ever measured the Vibes auto transmission atf fluid pump rate at engine idle speed?
If so, an EZ fluid exchange would be: drain/refill - run engine at idle 3.2 qts. worth - drain/refill - repeat.
Total fluid added = about 9 qts. with very little mixing of old and new fluids.

I completed my Transmission ATF fluid change following the directions in the link below.
My auto transmission ATF pumping rate at idle in PARK appears to be 1 qt. / 20 seconds.
I turned off the engine to add 1 quart of fresh fluid for each quart of old fluid pumped out. Then re-started the engine to pump out another quart.
