Transmission servicing 2000 Chevy Astro AWD Sign In

Greetings, Does the Automatic transmission share fluid with the transaxle on the Chevy Astro AWD?
I would like to replace more than the ATF in the pan when changing the filter.
Thankyou Richard

What trasnsaxle? It doesn't even have one.
If your talking about the transfer case, no they don't share fluid. Dropping the trans pan will only get you about 1/4 of the total fluid capacity.

The OEM Manual refers to: Transaxle.
I guess it is the transfer case. Thankyou

A transaxle is a transmission and differential combination. Your transmission is in the center of the truck so that is not possible. Transaxles are found in light vehicles that are basically front wheel drive. The engine, transmission and differential are all bolted together and the transmission and differential are one component.

If you want to get all fluid out the only way is to take it to a shop and have them use a flush machine. Otherwise you still have at least a quart in the torque converter.
I'm a big fan of doing things myself though so I would drain it and look at the fluid. If the fluid looks healthy (same color as the new fluid or close to it) I don't think you need to bother. Unless your transmission has been acting up.

I quite disagree with that.

Changing the fluid before there is an issue is extremely important. It can mean the difference between getting 100K out of your transmission and getting 250K out of it. Second, if you only drop the pant, you will leave closer to 8 quarts in the torque converter so it is very important to use the flush machine rather than drop the pan.
If the transmission has already been acting up, that is a very good reason to leave it alone because the damage is already done and fresh fluid can just hasten it's demise by cleaning out the varnish that's holding it together at that point.

I've always liked to add a drain plug, the drain plugs I have seen lately have looked mickey mouseish. Are there good quality plugs out there? Thanks

Richard
