question: transmission flushing - Page 2

I have done the tranny drain and pump-out about 10 times on different vehicles.........the principle is the same......

1)drop the pan and swap out the filter or just drain the pan if it has a plug and you are feeling lazy. replace pan.

2) replace the fluid in the pan(on average about 3 or 4 quarts

3) remove the return line from the radiator. you disconnect the rubber hose from the metal hose (most cases) you might need an extra hose. stick the return line a a jug. have someone start the car and shift though the gears. pump out 1 quart at a time(just take a few seconds). turn off the car and add a fresh quart......keep doing this until the crappy lifeless fluid turns in to fresh bubbly red fluid.....You have now replaced all the fluid in the tranny...........just draining the 3? quarts in the pan is not good enough......

the only additive I use is Lubegard. usually the red one is what i use.

*I also never bought into the foolishness that some crappy old fluid is acting like glue and holding your tranny together...and that your tranny will self destruct if you flush it.......my guess is if you do the flush and the tranyn dies the tranny was about to die anyways

if you do the flush my way and just do it by draining the pan and pumping the rest out you can do it in about 30 minutes.....its like a 2 part oil change.

also I am pretty sure the shops like Valvoline that do a tranny flush use the lubegard......they use the generic ATF and then add the appropriate lubegard.......supposedly the lubegard converts the generic ATF to the correct factory specs for the car.

----------

also if anyone in my area ever needs a tranny there a few ford techs that will rebuild your tranny for about $600. they charge and additional $400-500 if they do the removal and install.....

That is how I did it myself last time too cause I'm cheap.

I just had it flushed on the machine at a garage on Friday--that's what this thread is about. I couldn't get it flushed using Wynn--they had BP, but seeing as it was just flushed on a machine thoroughly, if someone has/can get me some wynn, I should be able to change the filter and fluid and put in the Wynn and be fine.

You're in Boston??? How would I contact one of these mechanics? I live close enough to Boston that I could make that work if/when the day comes the tranny needs a rebuild thanx

My 2011 has 30,000km right now. I plan to do this self-flush at 50,000km and every 50,000km thereafter, with Motorcraft ATF, no other addittives.

It was only $129. to have a local (non-dealer) garage flush it.

That is no to bad. They don't drop the pan and change the filter. You can do their method in your driveway for about $50 and in 45 minutes.

I've owned the truck 4 years and changed the filter/fluid 3 of those 4 years so I'm not concerned about the filter not being changed. And changing it all those times didn't make the difference flushing it did. I'm very pleased with the outcome--well worth the $. Its not perfect but better--it used to stick for about 15-20 minutes then shift fine. Now it sticks only slightly the first couple times it shifts and then its fine...don't know if it was the flush or the additives they used during/after the flush? Maybe if its the additive it might improve more?
