transmisson problex FIXED!!

[irishblessing]

well 700 miles ago i decided to flush my tranny first time in idk how long at 151k miles
well i didnt change the filter cause i though the flush would just be ok
at my friends shop they were changing a filter in a car and decided i would put mine on the lift and do it and WOW there was alot of sludge in there cleaned it all up put a new gasket and filter on filled up the fluid and she shifts so much smoother i cant even feel it no permanent damage im really stoked

Ask our local transmission shop about 'flushes' and you'll get an ear full of information. Sure they will flush the transmission--however they also drop the pan afterwards and change out the filter and pan gasket.

People at times fail to understand what a flush really does. All that crap gets backflushed/forward flushed etc... and it all still goes through the filter at some point in the process. And it stirs up quite a bit of gunk from the bottom of the pan, and gets in the filter.

Yes they sure do. Most flush machines don't really "flush" a transmission at all. All they do is use the transmission's own pump to pump the old fluid out while simultaneously pouring fresh fluid in, until all the old fluid has been exchanged with new fluid. It doesn't force fluid through the trans, and it doesn't push the fluid backwards. The transmission does exactly what it normally does while idling in park, so it doesn't stir up junk any more than it usually does.

There are some machines that actually do force fluid through the trans, but MOST of them work in the way I described above.

I've heard the machines recycle fluid--I dunno how--and you end up with other people's old fluid.

Best way to do it yourself is to disconnect both cooler lines, get a 3 gallon pail to catch old fluid and a 3 gallon pail to suck up new fluid and run it until you see new looking fluid going into the waste bucket. Then shut off the motor, reconnect the lines, restart, cycle and check the fluid to top it off. Haul the old to the recycle center.

That is how our Wynns machine works.

iff the tranny sucked fluid in from the return line thiss would be great but since it doesent any other idias

Turn engine on, wait for trans to pump out a few quarts of fluid. Shut engine off. Add a few quarts through the dipstick tube. Start engine again. Repeat.

 

[Ranger#1]

that would work but howmanny quarts are in the pan

 

[exbass94]

About 4. I would probably do 2 quarts at a time though.

 

[Shran]

I got about 4.5 quarts out of my A4LD when I pulled the pan.

BTW, if one were to pull the cooler lines like Will mentioned and do a fluid exchange that way, which line would you put in the waste bucket? Top or bottom?

 

[exbass94]

The fluid goes into the top of the radiator first, out the bottom, then through the external cooler. But I would put both lines into the bucket. Today, I found out that fluid comes out of both lines when they're disconnected for some reason.
