Re: Controversial 4l60e maintenance question

700r4 or 4l60-e and shifting funny = time for a full diagnostic and prob rebuild at-least some of it in my opinion .

when i was turning wrenches for a living i first looked at fluid color red to dark red i said o.k.

next was road test drive like grandma to hard core if shifted funky NO WAY would i flush it or filter and refill job .

the reason they tend to go south after this when there already ??? is all the grit is gone from the old fluid being out .

its a can of worms i hate to say . take a gamble or find a super good trans shop and let them look it over and do there magic .
