Tranny Flush deal or no deal?
 
Well today I took a ride to the dealership to pick up the front output shaft yoke nut i ordered and asked there service department how much a trans flush with new filter would cost there, they told me $159 plus they make the adjustments to the 32RH bands, sound like a deal?

You'll save $100 if you do a basic filter/fluid change yourself. If you have a lot of miles on your tranny and you've never had a flush before I don't recommend it.

Why don't you recommend a flush on a tranny with lots of miles and no previous flush?

jeepdude2003 11-12-2012 10:06 PM

I cant tell you why but my friends that is a mechanic for over 20years has told me the same thing he said if i have high miles and never been flushed it was more likely to have more problems after a flush then if i didnt do one i dont get it hes coming over tomorrow night if i remember ill post what he says

MillerFam 11-12-2012 10:09 PM

Yeah, that's interesting. I'd love a mechanic's explanation.

I have heard also that transmission flushes cause more harm than good. Drain, refill and change filter is supposed to be the way to go.

mckey73 11-12-2012 10:20 PM

Just do what the owners manual says as far as fluid/filter change intervals. If you are well beyond what is recommended a fluid/filter change won't hurt. First thing would be to check the fluid on the dipstick and if it's nice and red & your tranny isn't slipping you should be good. As far as the band adjustment goes, if you aren't having any issues don't mess with them.

As far as the flush goes, it's hard for me to pay for that one!

SeVeReDiStOrTiOn 11-12-2012 10:28 PM

The grime, shavings or whatever you want to call it can add friction to the bands keeping them from slipping. Some call it a myth and some swear by it. All I know is it happened to me in my 92 silverado. I had it flushed around 130k just for maintenance reasons and it started slipping a few hundred miles later. I remember pulling over and checking the fluid thinking it was low after the flush...nope. It lasted awhile longer but I eventually had it rebuilt.

Then there's the issue of breaking too much sludge loose at once causing blockage in the valve body or lines. I personally stick to filter changes now but everyone has their own thing.

Codysrubicon 11-12-2012 10:36 PM

Rather than a flush, I would recommend dropping the pan and changing the oil and filter. like the previous posters have said. if you are unsure of the PO's maintenance schedule, you don't want to do anything drastic. what you could do to get back on track though, Check the fluid color. If it is starting to look brown or discolored, change the oil and filter now and then do it again in about 10k miles. This should get it back to a regular interval to where you could go back to regular maintenance recommended by your owners manual. Of course, this is just a suggestion as I have no idea what your situation is.:hide:

In my 06 manual, it says that the fluid is good for life of vehicle unless contaminated by water. Many (if not most) vehicle manufacturers do not recommend fluid flushes, unless contaminated. Coolant flushes are usually the only ok flush to do.

I have no trust in a dealer what will perform a service that is not recommended by the engineers at Chrysler. The Service Bulletin I have attached the link to goes back to only 2005 vehicles. Previous years would require investigation, but same probably applies also.

Replacing the high detergent trans fluid in a high mileage vehicle (especially over 100k) when it has never been done before, is a risky endeavor. The detergent in the fresh oil can loosen old deposits in the nooks and crannies, and come loose and raise hell.

If somebody is having trans problems, replacing the fluid may be a solution, especially if somebody did not use OEM fluid at a previous service.

Tdog02 11-12-2012 10:56 PM

I'm not afraid of the trans service. My reason is if its used up then its used up. Getting the bands adjusted is a different story. You don't have to buy the torque wrench (inch pounds) to set the bands so 159 may be a good deal. You may need that wrench 1 or 2 times in the future...
I would do it at the stealership for that price. Just my opinion.

Recently had my tranny filter and fluid changed in my 04 wrangler X. It had 69k when I bought it about 4 months ago. The fluid was changed at 72k. I used Royal Purple, took 3 qts. Before the fluid change I had a to give it a little extra push when shifting to 1st. Now it's really smooth. Also replaced the clutch assembly. Dealerships just use Mopar.

Wait, I thought we were talking about automatic transmissions???

JeepWrangler4x4 11-13-2012 08:21 AM

Well thats why i was going to do it at the dealership... if the trans messes up after they flush it and adjust the bands and such, its not my prob.. :) but if i do it, then its my prob.. get what im saying

Bgtklbx 11-13-2012 08:38 AM

37 years as a German car tech. My experience is do not flush...waste of money. Do a basic service with filter and new fluid. My reasoning is you simply do not need the flush. If you are worried about contaminated fluid, or lots of crud in the tranny then do a secound drain and filter after about a thousand miles and then dont worry about it. My experience has been basic maint. and then leave it alone except for checking fluid level and fluid condition check. (smell and look). Hope this helps.

Well, I was just speaking from a recent experience in general terms.

jherrington 11-13-2012 11:04 AM

so, changing oil in a manual transmission that hasn't been changed regularly can mess it up also?

ninjaturtle0 11-13-2012 12:28 PM

wow never knew this.

Brought my 05 Jeep in 07/2012 with 57K on the odo and changed the Trans fluid as manual says to change at 60K. Checked the trans last week and it still looks new so I hope I'm fine.

Dextreme 11-13-2012 01:05 PM

One of the reasons why many suggest not to Flush is because it can cause particles resting quietly in the tranny not doing any harm and cause those particles end up somewhere else in the tranny where they do not belong. Simply draining leaves those particles alone.

Lots of people say their tranny (not just Jeeps) goes out about 1000 miles after a tranny flush. Many say they never had a problem. So its a little bit of a gamble as to what may happen. Do ya feel lucky? Do ya? :thumb:

No, the discussion is about "Flushing" an Automatic transmission. Manual transmission, ya just drain it and add new fluid.

With an Automatic transmission, just "draning it" does not get ALL the fluid out because there is bunch in the Torque Converter. Flushing the Automatic transmission removes all the oil. Some prefer to just "drain" what they can (like ya would with a manual tranny) and mix new oil in with the oil that didn't get drained.

wonder if this goes with everything, coolant, oil (not that i really ever heard of a flush but dyno oil to synthetic) etc.

They have coolant flushes, the gm tech at our local dealership suggested that gm recommends a coolant flush on my dads solstice gxp, now it's leaking coolant. I wouldn't do any flushes of any kind, they just seem to cause problems.

I know that. That other guy brought up manual transmissions so I was confused as to why he said that when clearly the discussion is on automatic transmissions.

I have designed torque converters for about a decade now. I have always heard that you just drain not flush. I've heard this from people in the industry as well as in training from SAE (society of automotive engineers). It only takes a very small particle take out a trans. If a small particle has found a place to live I would leave it there. So I would not flush I would just drain.

Did the dealership change the filter on your manual tranny or did you?

JeepWrangler4x4 11-18-2012 02:52 PM

i have a auto trans but i dont think manual trans have filters... i know my honda i owned didnt have a filter.. i didnt get it flushed yet still a little concerned bout having the dealership do anything to my jeep.. when i bought it from there it supposabley has all new u-joints, new exhaust, new brakes, about a month after i bought it, had to do all the brakes, calipers were sticking, brake chambers in the back were leaking, shoes and drums were no way new, and still had the stock u-joints in it when i changed them all again.. and every mount has broke off the exhaust after the tcase, so i doubt that was new..

So let me get this straight, you bought the jeep from them and all the "new" parts were completely wore out and you are still considering taking it back to them for service?
No way in hell would they ever see another vehicle of mine and everybody I know would know about it too.

JeepWrangler4x4 11-18-2012 09:44 PM

for trans flush.. but prolly just drop pan and refill like everyone saying
