Equinox - Changing Transmission Fluid?

Anyone know how to change the transmission fluid in a Chevrolet Equinox



2005? It has a Aisin 55-50 AW33 transmission (5sp fwd auto) There is one bolt on the bottom that probably can be used to drain There is a 5 sided with rounded corners bolt on the top of the transmission There is no dip stick or full tube.

Now I can measure what I drain out so thats not a problem, I use 1gallon clear jugs and use water to mark of 1,2,3,4qt.



The problem is that I can't see how to get the new Toyota T-IV fluid back into the transmission! A 5 sided bolt with rounded corners is not the type of wrench I have in my toolbox!



I called the dealer service department, they mentioned they do it on a lift and remove a smaller bolt to have it spit out transmission fluid and they open up a larger opening (I am guessing the 5 sided bolt) to pour new fluid in. They were not detailed enough for me to understand clearly.



One thought was to try to use the transmission fluid cooler lines, I could unhook them and use rubber hoses to reroute those lines to a drain pan and a



1 gallon jug of T-IV fluid, but will the transmission pump actually SUCK fluid back up into itself or does it need the pressure pushing from the pump to make a complete cycle? Some websites mentioned changing fluid this way but I thought that the transmission pump only worked on one side, and that since the cooling line is a completed circuit it would eventually return to the transmission after being cooled. Am I wrong in that it actually pumps fluid out but also pumps fluid back in as well and that placing the cooling lines into separate containers will actually work?

I don't own an Equinox but looked at a service manual recently. It looks like there's a drain plug and another plug on the bottom/side of the transmission to check fluid level. The fluid level check looks like a bolt & flange must be removed to get the dipstick out. My guess you'd have to fill thru this hole. Both are on the bottom so guessing that's why the dealer is doing it on a hoist.
