Brand Of Tranny Fluid Are U Using!!

I work at Advance Auto - when we recieve shipments, it all comes at once, from all different brands. We recieved one shipment of Advance Auto brand ATF, along with Valvoline ATF. A customer bought the Advance Auto brand, opened it up, and it was clear fluid with a gooey/sticky consistancy. It also smelled terrible, not anything like ATF THe Valvoline brand was fine, no issues at all.
I can go on and on with examples of the store brand being inferior, believe what you want, but my opinion is a good 80% of it is garbage.
Personally I've never had a problem buying stuff that's store brand, regardless of which store it comes from. I don't need a brand-name to keep me happy.
Anyway, as stated before, I don't keep the fluid in there long enough to matter anyway. In fact, it's time to change it, and I'll take $9.88 per gallon for Advance brand vs $14.88 for Valvoline any day. Especially when I need 2 gallons. My 4000 stalled, 79k mile, daily driven transmission seems to like it just fine...

Have you seen the average employee at a quick-lube establishment lately? 'Nuff said.
No thanks, I'd rather just change it often. It all got changed back in February anyway when I did the converter.
I actually read the user's manual. It said dexron III with mercon so I wouldn't use anything else. I bought some Coastal fluid for the converter swap I'm doing soon. These manufacturers have to meet the same SAE requirements so I don't see why it would matter as long as my trans temps stay low with it.

I also ran their Hi-Temp synthetic ATF in my built 4L60 for 6 years without any problem. Additional external filter and large cooler.

I use Dex3 from Advanced Auto.
All this oil has to meet specifications, so It has to do the job it's intended for. I don't think one brand is going to be that much different than another unless your talking synthetics. I just don't think its worth the money to buy a Valvoline over a auto parts house brand.
Motor oil is a little different I think. It comes from different base stocks so the oil that is refined better is going to be different than like a Group 1 oil.

you know what's funny... I used the Advanced cheapo brand in my 700R4 after I changed the converter in my old Camaro. It wasn't enough to fill it up; so there I was i the middle of the night, happy that I got it put al back together and could drive it again; anxious to get it out, so what did I do? I re-used the old fluid that was still sitting in the drain pan over to side that had been sitting there for about three weeks; I think it had a few grass particles in there as well... After I used that and filled it up, I put a shift kit in it about a few months later and drove the living hell outta that car for the next year. I never had a problem with it. I even manually shifted it, downshifting included, very very often. Nice explanation on the synthetic. I have always heard that, too.

As long as you get the Dexron/Mercon III, why would you waste money on RP or Amsoil? People get brainwashed into thinking more $$$ = Better product.
Not necessarily so. Store brand is fine, just change it often according to how much abuse it takes. Spend $5.00 a quart if it makes you feel better.
I have a Coan built 4L60E/Vig 3600 vert and am pushing 507 RWHP N/A,
Yet I use Autozone Coastal brand ATF. Why throw money away?
No synthetic in the trans, only in the LS1 427 stroker. Mobile one in that.
