Home Trans Flush

[SlkMerc]

Hey All -

I want to do my own flush/fill using the Dual Bucket/Hoses connected to In and Out/Car in reverse method. I would like to ask if anyone has pics marking the 2 hoses I need to disconnect. Also - how much does it hold when changing fluid this way? I will be dropping the pan as well - is the gasket reusable?

Thanks so much.

The pan gasket is reusable.

The two tranny lines go to the cooler which is part of the radiator.

Run the car for a bit and the hotter line will be coming from trans.

I'm sure you can figure out the rest.

2 bucket method? One hose will be under pressure, the other won't. It won't be under vacuum either. So the trans will just pump out fluid to one bucket until it's empty, then burn up from lack of lubricant.

I had a tranny flush and then 1500 miles later the trans started whining. We changed the filter and the noise went away and its been fine since. You may wanna pull the filter as well just to be on the safe side. The machine that's used for the flush has its own pump and fail safe systems so you don't run it dry and burn something up.

There you go, use the proper equipment or use the old-fashioned drop-pan method.

You will NOT burn up the transmission using the bucket method, I've done it for years(so have the GM guys, their torque converters haven't had drain plugs in the last 40 years or more)...

I just remove the line in to the cooler and connect a piece of hose to it, then start the engine and pump the fluid into a 5 gal bucket(use two buckets if you like)... Once the flow stops, shut it down and service the pan...When the pan is back in place, add 6-7 quarts, then start the engine and run until the color of the fluid flowing into the bucket changes to the new fluid... If it stops flowing before it changes color, shut it off and add 3-4 more quarts then run it again... Once you have finished, reconnect the cooler line, restart and add fluid as necessary...Leave it approx a 1/2 quart low till l it's up to temperature(30 min or more)and top it off... Done...

If your pan doesn't have a drain plug(only if added), you can pull the pan and service it first(probably getting a fluid bath), then add the 6-7 quarts and run it with the hose in the bucket till the fluid changes color... Remainder is as above...

Thanks for the write-up TFB!
I never knew how to do that. This will save me some bucks.
Cheers.

Just don't spill any cause that stuff stinks! :lol:

I've had many-an-armpit full of fluid over the years, so I just started going to the dealer. Didn't want to deal with that anymore.
By the time I leave the dealer, I'm out $200!!
Taxes; enviromental fees; disposal fees; labour; blah blah blah.
Now I don't have to.

Crack the Valve body loose and wait 2 hours....10+ quarts will drain out.

And the chance of the gasket being compromised is slim to none, but flame away.

Your welcome Rockettman...

If you attach the hose to the bucket so it won't possibly jump out or have a friend to help, a couple more quarts can be added while it is flowing into the bucket, otherwise you'll probably have to shut it off and add more fluid... That's due to a stock torque converter usually holds 7-8 quarts or more, but if you add that much to the pan before starting, it will likely run out of the transmission vent...

It's easy on my T-Bird with the 9.5" converter, just have to add around 6 quarts after a pan service then start running it into the bucket, I don't think that converter holds more than a gallon if that...

Only issue I have is the lower half of the converter below the hub won't be drained but that no doubt works...

Get a decent +2 quart trans pan with drain plug. I do a pan drop every 15K, then you really don't need to mess with the lines.

You also won't get the fluid out of the trans cooler as it has a 180F bypass in front of it. Add a piece of hose to the cooler line. I have never left it running till it stops - however you can pump out a gallon or so - the pan will be almost empty and easier/cleaner to remove.

Not sure which line? Add hose to both lines, put in bucket and start car. I usually only bleed out a gallon or so to be safe. Since getting drain plug pan don't do it at all.

PITA to remove VB and wait.

It is my understanding that putting the car in reverse and having a line attached to the in/out. One in a bucket (Im going with one that had a lid and a hose pass thru) with_____new Mercon V and the other line in an empty. Start car put in reverse, the new goes in and you watch the discharge til it runs clean. I do like the idea of draining some and then dropping the pan to service the filter and at least have a look in there. Magnet inspection and lollipop quest.
