AAMCO Trans service

[red94fourdoor]

Has anyone had their trans fluid changed at AAMCO with the power purge system that they have there? Is it worth the $$$ and does it really make any difference?


Thanks

I have not had a personal experience, but in general, you can do the purge....which will loosen and free up crap in your tranny....THEN you want to drop the pan and clean the filter reinstall, replace the 5 or so quarts and your tranny will be super clean.

Depending on mileage, use etc, you might be able to get by with a 30-50K drop the pan, filter and replace the lost fluid.....sticking to a strict regime, you will eventually replace the whole fluid.

Answering your question depends on the service, current conditions, use/abuse etc.....

No, dropping the pan will only allow you to change about 40-50% of the old fluid and the rest will be trapped in the torque convertor.

Best to do both, get it fully flushed at AAMCO and then go home an swap in a new filter.

Depends on the mileage somewhat. I always knock a hole in the pan just in front of the magnet to drain the fluid on first service, put a screw with a gasket in the pan to serve as a drain plug for future changes. Really makes a messy job much cleaner and easier. Service those 700R/4L60 trans. often and they will run 200K with ease. New filter kit and five quarts of fluid will do the job. Really don't see the need to pay $70 - $80 for this and hope they get it right.

you won't be able to put 5 qts in by draining the pan, you never get the fluid in the torque convertor.

I've heard you can do a purge yourself, does anyone know about this?? While getting mine flushed the guy told me all I need is some rubber hose and a few gallons of tranny fluid. He said you take the tranny line off the radiator add extensions, then put one hose in a full jug of tranny fluid and the other in an empty jug, crank the vehicle and the tranny will pump in the good and pump out the old.

Does anyone know if this is true or was the guy wanting to sell me a new tranny?

I should mention the same guy that put new ball joints in my impala and only pressed them in half way.

Tahahaha!

Although his fluid change method can be done, I wouldn't try it.

[blazee]

I wouldn't try it unless I knew for sure it would work.

I use that method all the time. I take off the top line, I have a person help me start it up for me, while I am in front watching. I connect a fitted line to the rad with a rubber hose and the line is routed to a jug. Start it up, let it drain. Just as it is starting to empty out, shut it off, and add a couple of litres(quarts) of fluid, start it up let that come through to the jug. The trick is to never let it run whitout oil, so as soon as is starts to stop flowing smoothy, shut it off, and your done. Reconnect line, drop pan, change filter, clean pan, new gasket, etc, etc. Refill tranny normally, and you just did your own flush. I must stress, you must not let the transmission run dry, if you do, damage is likely, other than that, piece of cake, takes a couple of hours for me from start to finish. I have never had a problem, and I have used this method many, many times.

They don't change the filter at AAMCO? My truck has 177k miles on it i bought it with 175k. I don't know when it was changed last.

there are specials run at come places or coupons for 29.99 trani flush by the time u bought the fluid youself you would be close in price. plus this does it 100%, then go home drop tht pan put in a filter and a new gasket and get the crap out of the pan. and your trani will be clean!!

the hose thing sounds shoody and flush is cheaper than a rebuilt.

i always try to find ways to do it myself but somethings have to be done!
