545RFE fluid change confusion
Hey All,
I fineally got off my rear and did the trans filters and attempted complete fluid change this weekend. When I was finished with the filters and pan I gave it 5 quarts, pulled of the trans line at the RAD cooler (the RH one is pressure, don't ask how I found out!)
I stuck some 3/8 hose on it and stuck in in a bucket. I started the enging and not so quickly learned after 5 quarts it only can out as I poured it in, so it looks like the fluid pumps from the pan thorough the cooler then to the TQ converter.
Does the other hose have vacume so I can stick it in a bucket of fresh ATF+4 and it will suck it into the Tourq converter and thorough the rest of the trans?
Has anyone else tried this?
I read a writeup of some guy doing this on a RAM but it definatly did not work on mine.
ANY comments are welcome.

Sounds like you went to alot of trouble, mess, and exspense. I personally would just pay the small fee to have it done by a pro. Or maybe you are the type that enjoys doing it yourself. Anyway I would think that if one hose pumps out the fluid the other would draw it in. But perhaps the sucktion is not strong enough to pull it up from a bucket. You may have to feed the hose from up above some how.

No, it most definitely goes through the Torque Converter, into the cooler, and back to the transmission.
The torque converter is where a lot of heat is produced, so it wouldn't make sense for it to go through a cooler, into the converter, and back into the transmission sump.
Why do you think that 5 quarts that came out was the same 5 quarts you put in? Was it really clean looking, and the fluid WAS kind of dirty?
When doing the fluid on my 1996, I always disconnected the return line, and as fluid was coming out of the cooler, I would pour in (through the dipstick/filler tube) the new fluid.

I got 6 qts from the pan, I used gallon milk jugs and that fluid was dark red. Once I started the engine I immediatly got 5 quarts in the next jugs, much lighter red thad from the pan, then it almost stopped coming out. As I poured several quarts in the filler tube, it would come out the same rate, when I stopped, it stopped (these jugs were all much lighter red color).
Dodgerules86 I hope you are correct, if so I did not waste 8 qts of fluid!
I guess I will find a shop that has a fluid transfer machine and supply them the ATF+4. Most shops I have talked to want to use there universal fluid and add an additive that brings it to ATF+4 specs, I don't trust that.
It is much smoother with the fluid change though, very nice.
Oh and Frenchy, nothing like a wark sunday afternoon and ATF running down your arms!
Yah, I would actually like to drive a 6 speed to see how they perform.
Thanks for the comments,

Frenchy, the manual is nice, but its a dieing tranny... ever wonder why that is?
Why would Ferrari sell roughly 80% of its F430's with a triptronic sequential gear box? (thats not a manual/clutch)
Why does Porshe's 911 turbo run 0-60 in 3.7s with a 6 speed manual, but 3.4s a 5 speed triptronic?
I am pretty sure most would say that F1 is a pure form of racing... no manuals in those cars.
I am not saying that a Manual isn't the purest form of driving, but lets face it. New technology makes it pretty much useless in performance driving. Where the high end goes, the industry almost always follows.
The SLR McLaren doesnt even have the option for a manual gear box.
So why are all these companies going to an electronically triggered and hydraulically actuated transmission?
I think its to protect the car from the driver honestly...
I will quote this, as its worded better than my ramblings...
I am not saying a manual is a bad thing, but pretty soon, its not even going to be a "thing"...
Plus when top performance manufactures are putting down better specs with autos, its not real hard to see where the technology is.

Taking the driver out of the shifting business is good business for the manufacturers. Even the very best modern shiftable automatic — VW/Audi's brilliant dual-clutch Direct Shift Gearbox (DSG) — will keep the driver from doing anything that might harm the drivetrain. Why even mark the red line on a tachometer if the computers won't allow it to be exceeded anyhow?
Precise computer controls make meeting emissions and fuel-economy goals more straightforward; they can protect against driver behavior that can result in warranty claims, plus the market long ago showed it preferred automatics. And in raw performance, there is less and less measurable advantage for manual transmissions. Throw in the rise of computer-dependent hybrids and other technologies and it's hard to see how manual transmissions can long survive.

There is still no better feeling than pressing in the clutch pedal, shifting into gear, releasing the pedal, and going. (And repeating)
Even better when your in the passenger seat, and this hot chick is doing the driving, and you know that "Hey! This chick knows how to drive."
Instead of "Oh my! You mean I have to select 'D' and turn a steering wheel?"
I heart my manual gearboxes.

You mean there is reasons other than this?
I just asked a girl if she wanted to drive my truck the other night, she was like, uhmmm... no.
Then blah blah blah, I started my truck up and moved it, and she asked some people if my truck was a manual cuz I was giving it gas before it would move, ie. it wasn't lurching forward without me giving it gas.
She walked over, and screamed, "Why the hell didn't you tell me it was a manual! No **** I want to drive it!"
I denied her. I said, I offered once, and that's all you get...

I think if more cars were manuals, the country would be a little less fat.
Instead of having one hand on the wheel and the other clinching a double-quarter pounder, it would be wheel and stick.
Although, while it would be harder to do, people would still talk and drive. Or text and drive. Or sext and drive!
OK, maybe with how people in this country are with multi-tasking, we are better off with mostly automatics. (Or not. This way we can "thin the heard")
