Changing Transmission fluid, how much quarts?

Last time I changed my transmission fluid, it was like 3 years ago. and I can't remember how much oil (fluid) I used.... my local autozone says I need 7.5 quarters, but I think its too much? Have any of you guys change transmission fluid recently? how much oil did you use??
 


By change I assume you mean pan drop and filter change then yes 8qts ish start with 4 and start it up and add till full. flush takes 12qt
 
I have to do this soon too. My last "flush" was at the 60k mile service. Now I have 100k.

I have a tranny cooler and the shop didn't put in enough fluid in so the trans fluid level was low and it crapped out 5k miles later. I was dumb to not check it afterward.

That $2,800 bill from AAMCO taught me to do all my own maintenance. :(
 
And whats the difference between transmission fluid change and filter and "flush"? since "flush" takes more I wonder that exactly means. What I do is drop the pan and let the fluid drain, change filter put the pan back and refill. So when I do this, not all fluid is drained? what is the meaning of "flush"?
 
When you drop the pan, some of the fluid doesn't drain out because it's left in places like the torque converter, valve body, etc. The in-line transmission machines (e.g. the T-Tech machines used at places like Jiffy Lube) connect into your transmission lines and replace the fluid as it's cycled through the transmission. They get more of the fluid out, but you'd still have to drop the pan if you want to replace the filter.

IMO, dropping the pan to change 2/3 of the fluid and the filter is better than changing more (though probably not all) of the fluid but not the filter.

Another type of flush is a pressurized flush designed to force contaminants out of the system. These usually aren't recommended, as contaminants can be dislodged from areas where they're not causing harm and deposited in areas where they will cause harm.
 


We usually drop the pan and change the filter, then if there is no big stuff in the pan we flush it. We use an in line snapon machine it changes out all the fluid, cuz the trans pumps into the machine and the machine returns new fluid. If you are keeping up on the maintain ace pan drops are plenty.
 
oh I understand now, I guess I'm just gonna do the "basic" like always, drain, drop the pan, change the filter and refill :) cause taking it to the shop gets expensive!

Same thing happened to me about Sept. 09. I had a local trans shop give me a trans fluid change. They didnt fill it up enough and about 4 months later I need a rebuilt trans. $1650 for a rebuilt trans thru a local trans shop. That taught me to check the fluid after any work is done on my car.
 


now, talking about transmission fluid, how do you guys check fluid level?? what is the best time/way to check fluid level? cause sometimes I do it in the morning: I crank up my car, I shift gears pausing for 10 seconds in each gear, from park, reverse, neutral, d, 3, 2, 1. then go back to park doing the same. then I check my fluid and it says its fine, but when I drive it for about 10 minutes and check it again and may read low or overfilled...?? what? lol
 
Don't mean to threadjack but does anyone know of a chain that does the pressurized power flush? I don't believe jiffy lube uses a pressurized machine anymore, but not sure as I haven't worked there in a few years. I have a sticking tcc solenoid and I'm told this may correct the problem rather than having the side cover removed which will run me about 400 bucks.
