not really understanding this one.
Got a question here because I'm not really understanding this. and if I'm a retard just tell me I'm a retard it won't hurt my feelings
.
But why is it that I keep reading and hearing from people that you shouldn't change your tranny fluid? I guess its something if its never been serviced ( I don't know if it ever has and gramps dead so i can't really ask him) truck has 178k and it doesn't shift weird shift like every other psd e4od I've ever been in and the trans fluid is not burnt actually in pretty good shape if you ask me. but everyone tells me that I shouldn't change it because it will affect the life of the trans.. My only problem with this is. I'm from Indiana truck is from Indiana all its life. and I now live in texas and in case you don't know its a hell of alot hotter down here than up there. granted I've only been here about 3 months but it hasn't been hot.. but wouldn't fresh fluid with a new filter be a lot easier on the trans and make it last longer.. that just my observation and why you/I change ever other fluid.. Whatcha ya'll think?

lol, its ok I've always been a little slow. you don't have to rub it in
..Yea thats what I hear to but I still don't understand how it can shorten the life of the trans.. if that was the case lets go ahead and stop changing the oil too. its the same effect

Hey Now! go easy!
I just found this...
Don't confuse the shop air powered tranny machines with the BG Machine which adds no pressure but relies on the tranny internal pump to just pump out old and pump in new.It's the added pressure from the old style machine that does them in.
A replacement bladder in a BG machine cost $1,000 so cheaper machine use an air pump with the attended RISK of the operator not knowing that 30 psi is max for a JATCO where shop air may be 100 psi..........bam a destroyed transmission.
Male techs just like males in general may not read the instructions carefully and do required research!
Now circulating the {PRIMARY STEP} BG Quick Clean SOLVENT thru the tranny for 15 minutes does loosen the clutch wear material and varnish is often hurried or not understood!
The PROPER exhange process and analysis requires a technican familar with JATCO units to achieve best results.
Look of ATF before contemplating the process, timing the exchange with a stop watch and analysis of pressures created by internal pump.
Most importantly is deciding whether to do the entire process again immediately based on color, smell, and taste [if you have the tongue for the job]. Like a coffee or wine taster.
I see many where once is not enough to restore the circulating ATF to perfection.
If you think about it working an oil well or refinery or eating fast food is much worse than tasting/smelling a drop of petrochemical.
Humm some stuff to think about there.... and yes I've heard of people who have lost trans after a flush with high mileage...

Unless there total idiots, when they do a flush the filter is done at the same time (thats what they did on mine) I think the point I was trying to get across with that is there are different types of flushers, looks like the positive pressure one may give you issues where as the bladder style one uses the tranny pump to circulate the fluid is much better

Drop the pan, change the filter, drain the Torque converter and refill. Chances are just as good that your tranny will fail after or fail from not changing out the fluid.

x3 with Tim
It's an Old wives tale IMO....Changing fluids and filters should not harm anything. I think the tale comes from someone who had a failing trans and decided to do a pan drop/filter & fluid change to fix it....the trans failed anyway then blamed the new fluid and filter.
Trans flushes that do not include replacing the filter is asking for trouble. Unlike the filter for your engine there is no way to bypass the filter as it becomes dirty/plugged.

Ive had people tell me the same thing. If you have never changed your fluid and its way past due (like 100,000 mi)they say its better to leave it alone. If its done regular like its supposed to its OK. I say thats BS of course regular scheduled changes are best, I dont see harm In changing it at any time.

Rob,
I am a befiever in this. I have done it and had bad luck. If the fluid has not been changed in 100k miles the inside of the transmission will have sludge build up. Like the inside of a valve cover on an old motor. Not as bad but it will have some. Fresh fluid will break this stuff loose and send it through the tranny. That is what kills em. But, as you said your haveing some problems anyway. Sounds to me like its gonna go anyway.

Like Tim said, if your fluid has been in there that long, it's just a matter of time before it's an issue anyways. I'm go with his drain and fill method, gonna be alot cheaper than a flush and easier on everything in the trans

I remember a discussion like this here several months ago and someone said if you're worried about old sludge, gunk, goo, etc. breaking loose with new fluid maybe changing again after a few thousand miles would help.
