IPd transmission flush hose kit

[asummers]

Has anyone used the IPd transmission flush hose kit to replace their transmission fluid?
One of the warnings talks about the transmission not working at all after a fluid replacement if your old fluid is really old, black, and never been changed.
Anybody had this experience, or had bad fluid, and changed it with this hose method. And had the tranny work good after that?
Basically, you disconnect the lower transmission line from the radiator, install a clear hose on it, run the car until 2 quarts comes out, then add 2 quarts, and repeat the process until you get good fluid.

The flush vs drain argument. If you search you will find many responses on this topic.

I have had no problems with the IPD method and their kit works fine. I would not suggest this method for a transmission with a vane pump due to pump wear concerns. Most Volvo (Aisin Warner) transmissions do not use a vane pump.

I have seen/read about many instances where a pulsating flush machine does damage.

I also see no issue with the multiple drain and refill method except the cost of the extra fluid and extra time needed. I was happy to find that this method is best for those with no place to work on their car. I suggest a suction tool to remove the fluid and a funnel to replace it on transmissions without a drain plug or those who have no place to work on their car.

When I was in college I was not allowed to work on my car at my apartment. I bought a suction pump like this one

and a case of trans fluid and started my 3 am trans fluid activities. I always checked the dipstick the next day to make sure I had enough fluid. After a few weeks of sneaking out and doing it the fluid was much better and I knew almost exactly how much it was going to remove.

Now that I have a place to work on cars and proper tools I like the 1 time flush method best. I just did a car that had no service to the transmission in aprox 115K. Flush method worked fine on that car. It also had a Aisin Warner transmission but was a toyota.

Can you remove both lines from the radiator? Have the line out to the cooler go into a bucket to catch the old fluid. Then using a gallon jug siphon the fluid out with a hose attached to the return line. Or would the transmission only push the fluid and not siphon it back?

This sure would be a easier way of doing it if it would work. I understand you will need more then one gallon but you could line them up and when one is empty just put the siphon tube into the next gallon.

You still would need to change the filter and clean the pan. But then after that you could add the 4 quarts from the pan drop and then flush the remainder of the fluid right?

Unfortunately you can't use the return line as a siphon as it is not directly connected to the pump and the case is vented. You could seal the air bleeds and then use a vaccuum pump but its quite a bit of work.

Some use a transfer tube where the force of the pumped fluid pushed the new fluid in. This tube has a moving sealed plate betweent he old and new fluid.

Its easier for me to drain the old fluid, replace filter if the trans has a replacable one, seal up the drain plug or pan, fill the trans with fresh fluid and let the pump of the trans pump it out. You can always add through the dipstick on the 4 and 5 speed models and there is a fill port on the 6 speed in the front of the trans ( the rear bolt (firewall side)that looks similar holds a band and you will need to open the trans up to fix it - do not remove the top rear torx plug)
