Transmission flush

[patrick hubbard]

I'm wanting to do a transmission flush but I'm having trouble finding a place to hook up the transmission flush machine that I have at work. Any help would be appreciated

Read the whole thing - the first part is good but leaves out a few important details covered in the later posts.

Thanks. Now I know it's the upper hose on the cooler

NO MACHINE! Let the transmission pump its own fluid out.

It does. The machine has a tank in it that has a bladder inside as old fluid comes in it pushes new fluid out at the same rate old comes into the machine cu

I wanna say the top hose coming out is the hot fluid and the bottom is the supply. Its been over a year since I ran mine through a flush machine. Though within a few seconds of starting the process you should be able to tell if you have your hoses switched. I did this to both of mine before adding the tranny coolers to them.

Just wanted to say always replace the filters on these. Its just a good idea.

i feel like id only be comfortable with just changing the filter and replacing the fluid. here in new york theres an actual legal disclosure not sure what you'd call it. but it protects shops against premature tranny failures due to tranny flushes, changes and what not.

also I noticed the guy says tighten tranny pan bolts to 97 ft lbs?

97ft lbs? No more than 112 inch pounds...

I'd rather pump old fluid until the pan is dry, drop the pan and clean and replace filter, add 2.5 gallons plus the amount left in the pan, and pump again until the pan is dry, and add the final .6 gallons. Pumping in new fluid at the same time instead ensures that you get a nice mix of new and old in the pan while it is flushing, and agitates anything loose in the pan that may have been coating the pan, filter, or internals.

The place to take fluid is the return line back to the transmission from the cooler. Out of the radiator cooler, follow one line to the aux cooler input, follow the other line out of the cooler, and disconnect this line. One might remove, agitate, and dump the cooler as one of the first steps, but that's asking for problems as much as it is solving them.

Disconnect this line highlighted in red, at the cooler if you have no other disconnection points in the line other than at the transmission (needing a disconnect tool). You can put a drain hose on the cooler outlet into a bucket if not your machine, that way you can see when it starts to sputter air:

Disconnect this line highlighted in red,

WRONG LINE !
That is the power steering line.

Take off the TOP hose, #7.

 

[patrick hubbard]

That's what I thought

I'm with everyone else. People on automotive boards alot see too many tranny failures with the flush machines. Drop the pan change the filter. I've also seen alot of bad AX4N rebuild and reman units fail early. I would mitigate risk to original trans if it was my car. I let my GenIII go because of tranny failure and didn't want to deal with rebuild

Yes, oops, callout #6 is the power steering fluid line. #7 "clamp" is not helpful, but that's your spot above #6. Fixed the picture.

Hard to track the lines out of the transmission from this picture.
