TRANS FLUSH DISASTER!!!

[a7tl46]

'm waitng for my replacement trans for the 94 AWD, I figure let me flush the fluid, waht the heck. Found the method in the archives. Pulled the UPPER LINE from the radiator and rigged up the hose bucket thing. Started the engine and the trans fluid started gushing out the radiator port I removed the line from. WTF???? Went back and checked figured I removed the upper when it should be the lower, but nope I read it correctly. What gives?

If you follow the upper line back to the transmission, which port on the transmission does said line attach to, the upper or lower?

upper to the trans

Not trying to be lazy here but which thread did you look up in the archives?

This one...



First change the filter by removing the trans pan and dumping the fluid then remove the old filter and make sure the ring seal comes off with the filter if not take a small screw driver and pull the rubber ring out. then install the new filter. then remove the top trans coolant line from the radiator. You will need to purchase a clear rubber hose from a local hardware store big enough to fit over the end of the line then clamp it. open and set on a close table 9 quarts of trans fluid put the other end of the clear line in a 5 gal bucket.
Clamp it to the side of the bucket so it won't fly out from pressure. start the engine and start pouring the new fluid in as you watch the old stuff come out. after approx 7 or so quarts you should see the fluid coming out, turn redder and cleaner. At this time you shut off the engine and let it cool so you can check level and top it off. DO not allow the transmission to run out completely.

Yeah, that's incorrect.

All GM's will barf out trans fluid from the top of the rad.

So, do I put a fitting in the upper rad to trans outlet and connect a hose and pump it out that way? Or disconnect the lower trans to rad tube, connect a hose to the inlet tube to rad and go that way?

May have answered my own question. If either would work, I would think the upper solution is easier. No?

Yes, either way will work. Sorry about the confusion. I found two others that listed using the lower radiator line.

It;s a lot cleaner and easier if you can connect to the top of the rad.

[a7tl46]

going to use the top. Easier than crawling under for the lower. Plus I can thread a hose connector into the radiator and clamp a hose to it. Seems like a better setup to me. BTW what's the thread fitting size?
