Automatic Transmission fluid flush

[Buckmark]

I'll give you credit for at least doing some maintinance, better than none.

buy a lottery ticket, your a lucky man

I do an still cant win, got 4 out of 5 numbers, but that was only worth a c-note.

On another note..  Small shop? How well do you know this mechanic? Sales tactic?  I remember when I ran a gas station with service bays. Oh, we did tires and oil leaks and alignments and oil changes, brake jobs.. tuneups. Anything shy of pulling a tranny, diff or engine. With every oil change we had a list (that I wrote) of things to check and ask the customer if they wanted us to replace. Who really changes their antifreeze/coolant?.. Or thier air filter when they should? We'd talk the customer into another job. It was easy to look at the owners manual to see when the prescribed interval was to convince the auto owner.

They are an independent shop that will do everything including transmissions, engine rebuilds yada, yada, yada. I've been using them for a couple of years now. I know a couple of other people who use them too. They do great work for a good price and won't try to upsell you anything that isn't necessary.

Now that we have gone almost 4 pages, how about a show of hands as to whether he should or should not have this service performend.
Yes.

YES

For any of you Dodge truck owners, DO NOT flush the 47RH, 47 RE or 48RE transmissions.
Drain the pan, change the filter at the bare minumum.  Drill and tap the convertor and get rid of that fluid is even better.
47RH thru 48RE covers model years '94 thru early '07 with the CTD engine.
ATF+4 or greater only.

Chrysler says no flushes at all.

a transmission flush is not necessary.

I say NO. How are you gonna see if there's a trans issue developing when you don't pull the pan and instead you flush everything out without looking?

Read my first response to this post...

[jackelope]

I did.
That would be the only way to see it but then you're double-dipping and it costs 2x the amount. I'm one of those types that doesn't necessarily believe in the need for trans flushes in case you haven't figured that out yet.

For the sake of argument here we are talking a Kia Rio and no other Makes.
From what we have gathered the vehicle has 85k on it.
Has had the ATF filter changed once at 35k.
We do not know the year of the vehicle but a sample of Kia Rio recommendations and not others, is under "Normal" Driving conditions the ATF should be serviced at 105k, no recommendation on the type of service just that a service should be performend.
Very few people actually fall into the "Normal" service catagory.
If we look at "Severe" service the recommended interval is now at every 30k, again with no mention to what type, just service.
I am unable to find a recommendation on the filter for any service interval.
So given that the vehicle has 50k since the last filter change/service, my recommendation would be again, pull the pan, replace the filter and machine service (flush) out the system on this Kia Rio.

If Dodge/Chrysler, Toyota or whomever did not have a "Do Not Flush" service bulletin on there vehicles then the service departments would be selling them.

Yes.  

Uhhh... Yes.   You are not going to hurt your transmission by flushing it out unless  it is the consistancy of mud.  Sounds like the fluid is ok so flush it out.  If your worried about it then drain the fluid and change the filter and then drain the torque converter. Fill 'er up and you'll be good to go.

[JackOfAllTrades]

Disagree'd. A chemical presure flush will knock out a whole lot more 'normal sludge' than just a drain and filter change will.

I vote drain and filter change if anything at all.

How are you gonna see if there's a trans issue developing when you don't pull the pan and instead you flush everything out without looking?

By sending the oil sample off to a lab to be analized to see what is breaking down in the transmission. 

I've done it to my truck diesel 'engine' oil twice. Nothing abnormal reported.

Would I do that for a lesser vehicle that I didn't expect to run for 400,000 miles? No.

pressure flush= headaches. do a drain and refill plus a filter if you are worried. if you are curious, pull a sample and get it tested.....pretty easy and answers all the questions.

[mhadix]

just drain and refill. do not flush it

never done it or had it done to any of my customer's vehicles. one time i had a grand cherokee that jiffy lube forgot to put oil in and they had us pull an oil sample and they sent it to a lab after we put oil back in it. thats a whole nother topic...
