so i recently came back from a camping trip / wheeling trip and busted my aux derale tranny cooler mounted underneath the rear of my bed so i bypassed the aux cooler connecting the inlet hose to oulet hose to get home i was 2 quarts down but still safe to make a 100 mile trip back . i filled up what i lost and checking the fluid level in neutral after the truck was a little warmed up and it registers now at the correct safe level but the atf+4 is a little bubbly what can this mean i have a BD stage 5 trackmaster trans in the truck
