Ok so I pulled my tranny out today- I drained the pan, pulled out the TC and drained it as best I could and then dropped the pan to replace the filter.. I tipped it up on its bellhousing and drained some fluid out of the dipstick also.. how much fluid you think it will take?

 

Any ideas?

 

My book says approximately 4 qts for an auto.

 

Ya its an auto

 

My '88 AW4 takes 4 qts after I drop/drain the pan and nothing else. My Chilton's book shows 17 pts as total capacity which would include torque converter, valve body, etc. So if you dropped your tranny, drained your TC the best you could and tipped up your tranny to drain... you're probably lookin at about 7-8 qts, depending on whatever is still in your tranny/TC... I'd go on the high side to be safe.

 

What's it take to get all 17 quarts out?

 

What is the recommended trans fluid for the AW4?

 

Dextron II

 

I don't know about any 17 quarts... that's a lot of ATF. But the capacity chart in my Chilton book shows 17 pints, as if you were putting it in a dry rebuilt tranny and TC.

X2 on the Dexron II but you hardly ever see it anymore. Dexron III works.

 

You're right...it's pints. I musta been thinking about beer.

 

ahahaha...

 

4 quarts to start the day. lol =16 pints. the book said approximately.

 

Does anyone know how to get all - or most - of the fluid out of the trans while it is in the car? I'd like to freshen up mine but just draining it and refilling and only getting 1/3 or 1/2 the fluid out doesn't seem the way to go.

 

2 pints = 1 quart back in the day, but due to inflation over the years 4 pints to a quart might be right nowadays... :-)

I don't know of any way to get most of it out of a transmission with it in the car. Either drain/refill your pan a few times, which is a pain and a waste of good ATF, or take it to a shop that can flush the system. I've never taken mine to an oil-change shop, but I'd think it would be cheaper to change it on my own a few times. If you're pretty handy with stuff you might be able to put together your own flushing rig.

 

I gave some thought to the shop flush...but what are THEY flushing with? I mean, unless it's AIR, it's fluid...and why put their flush fluid into the trans? You know the analogy...how do you know where their fluid has been? I mean, it could have picked up some serious STDs from a Blazer or a minivan.
