but how many auto tranny has actually blow up due to flushing it? so far i havent really hear any |
There are plenty of examples.. they all have to do with automatic transmissions that have "lifetime" fluids. It is a damned if you do it, damned if you don't scenario. The story forget to point out that most people who frequent these places don't care about their cars in the first place. There are so many make and models of cars and obviously the technicians only care about selling the service, it is statistically impossible that failures don't happen. Quote:

- My dad took car in for service (1989 Oldsmobile Cutlas Calais) to Dennison GM. - Gets duped for "transmission flush" while it was there. (Car had ABSOLUTELY NO PROBLEMS with the transmission prior to flush) - After flush, transmission exhibits noticeable slippage in higher RPMS, when shifting into 3rd gear. I do not believe it to be coincidence that perfectly functioning transmission should start slipping and shifting poorly after a transmission flush. |

Mr. Lube is no exception Watch for mr. lube techs ripping you off. They will always recommend engine flushes and fuel system cleaning. Watch out! |

im really really surprised :eek::eek::eek: with things like this it should be STICKY worth it that anyone with automatic tranny should be 101% well informed and alert!!!! you would think wow, i havent change my tranny fluid for awhile. Time to treat her better, yet it turns out the opposite! And we all know transmission repairs costs a lotttt if not more than an engine. I spoke to a mechanic who has been repairing car for roughly 28 years, and he recently bought a flushing machine (does work at his garage now semi retired) and the machine was not cheap! Logically speaking you would think you want no residude left mixing the oil with new oil right? otherwise whats the point? its like taking a shower and only soap the upper half body and forget the lower part. So i thought wow cool, flushing the tranny SEEMS to be the proper way to do so. Now im really afraid to tell relatives/parents/friends to change their tranny oil. Question is if we are not suppose to use the flushing machine (which actually costs more! becuz it requires more oil than drain and fill ironically) does that mean when we change out tranny oil it will never be 100% clean? more like 65-70% clean? since you cant get the remaining old oil inside the torque converter without flushing it? Something this serious should be discussed more, afterall this is a car forum as well as an engine + transmission is basically a heart to a car. :(:(:(:( |

usually when you flush, your flushing out the crap that is holding the transmission together |
I got fucked by jiffy lube, they screwed up my car and then denied doing anything to it. they even made me get a tranny flush and everything. |
No logically speaking you should do what the engineers who designed the transmission tells you to do, instead of what a shop thinks you should do. The engineers designed the machines, so follow what they recommend. Automatic transmissions are powered by hydraulic pressure. The problem with flushing is you mess up the pressure, you might wreck the valve, you push debris into clutch packs.. there might not be enough fluid after engine start.. there are tons of potential problems. eg here is the proper way of changing transmission fluid on a BMW http://www.pelicanparts.com/bmw/tech...Fluid_Auto.htm It is time consuming that's why shop resort to transmission flusing machines and hope for the best.. places like Jiffy lube etc.. as long as you leave the bay, it is okay.

depends on who's the tech. :thumbsup: i got in shit for not selling enough. you know why? cuz lots of the cars dont need it. |
in a hurry right now, will read article tomorrow ok so long story short it is ok to drain and fill on most tranny and be fine with it? leave the resiude and have a 70% new oil in a transmission? :confused: Since thats probably the best way without damaging ur expensive tranny? |
^ thats how the honda techs do it. simple drain and fill. even they said tranny flushing isnt healthy for those honda transmissions. |
Quote:
Now, I believe companies like Honda specify repeated drain + fill for their automatic transmissions. You won't have 100% clean fluid in there but it's good enough. That's what I do for my customers and by the 2nd drain the fluid comes out fairly clean. This is very time consuming though and obviously doesn't make sense to business owners and managers or their typical customers. |
Those guys doing the reporting are doing just as much harm as the shops they're investigating. What they're saying is: "Flushes, purges and injector cleaning are useless services and have the potential to seriously damage your vehicle" when they should be saying: "You should never do a half-assed job when performing service on your vehicle, especialy when it comes to things like changing tranny fluid...." The problem is the people performing the work, not the actual work itself. How many people who see this report are going to stop doing fluid changes on their transmission because they think it will blow up? |

shiet..i got a engine flush a while ago at mr lube.good thing i dont own the car...return it after the lease. |
I've been working at a dealership for the last 7 years now and never knew about getting proper service for your car. but now i realize that maitence is important for the longevity of the car. I myself don't sell to many flushes at the front counter however the other service advisors do. I usally let the techs look the car over first before any recommendations. However I have seen the other side of the fence where a Hot Oil Flush and FUEL INJECTOR PURGE have fixed cars with rough running issues. And customers telling me the got X km/l more after the purge. I agree that older cars that have never had servicing, the trans flush for example, I won't recommend because its opening a can of worms. However i have seen vehicles (awd's) that have never done a rear diff service, be drained and have metal filings in it, and the suv's that have them done regularly have no issues. Its not jiffy lubes etc fault. They are trained to SELL...they often have spiff programs for the Tech and the advisors. you always have the option to say NO. |

This one in particular does not contain kerosene so that the damage is minimal compare to other ones. However they charge something like $20 for a flush, and this bottle cost them only $2.49 each. http://www.kleenflo.com/en/productpa...oducts/637.gif |
