what tranny fluid is for the 2.4?

i went to a tranny shop the other day to see price on a tranny fluid change and the guy told me dex 6, but googling and reading numerous forums it seems everyone uses dex 3..

input?? im changing my own fluid cause every price quote i get is like 100-150... or i can buy fluid myself and do it for 25$

edit; any specific tranny fluid you guys would reccomend?

 

i dont feel like explaing why and such, but use dex 6, i would personally get gm's brand

 

i know you dont want to, but can u explain....


also, i just ran to my car and checked the manual also:

manual transaxle (2.2 & 2.4) - dex 3 atf. look for "approved for the h-specification"
manual transaxle (2.0 supercharged) - part no. 21018899
automatic transaxle - dex 6 atf.

sooo, i have a 2.4 manual... still use dex 6?

i have dex 6 already in my possession, but was thinking of using mobil 1 synth (dex 3, approved for the h-spec) instead....????

 

you can put dex 6 in a trans with dex 3, and it will work fine, it doesnt matter if its 1 quart 6 the rest 3
or if your doing a total fluid change, 6 will always go into 3,
dex 6 is a more advanced fluid with a longer life, and better qualities
6 is just a better fluid, and its a drop in upgrade for all vehicles with 3,

heres an article from zzp about dex 3 and 6

"Here’s what GM has to say about the new DEXRON VI:
Automatic transmission fluid (ATF) is considered the life-blood of the automatic transmission. It is used to transfer power in the torque converter and provide the pressure to apply the transmission’s various clutches and bands. It also is used to clean, lubricate and cool the components of the transmission. GM’s new transmission fluid, DEXRONŽ-VI, was developed to have a more consistent viscosity profile; a more consistent shift performance in extreme conditions; and less degradation over time.
Beginning with the design and development of GM’s new Hydra-Matic 6-speed rear-wheel-drive transmissions, GM Powertrain engineers determined the need for a new transmission fluid to withstand the complexity of the clutch-to-clutch transmission operation. Additionally, GM engineers identified opportunities to improve viscosity, durability, and impact on fuel economy with a new fluid.
"The development of DEXRONŽ-VI is the first time an automotive company has worked so closely with petroleum and additive companies to develop a new fluid," says Roy Fewkes, driveline fluids group leader, GM Powertrain. "The result is a new fluid that significantly outperforms existing fluids in every aspect. In fact, we have had to significantly extend the length of our durability tests to fully test the fluid’s capability."
Internal GM tests have demonstrated DEXRONŽ-VI to deliver more than twice the durability and stability in friction tests compared to existing fluids. It also has demonstrated superior performance in pitting, foaming, oxidation and shear stability tests.
Here’s what it means for ZZPerformance and your our transmissions:

We believe in delivering the best possible transmission in the world. This means keeping up on all the latest technologies and constantly striving to improve all of our product offerings. The new Dexron 6 transmission fluid allows us to deliver a transmission that lasts longer, performs better and at the same time gets better gas mileage. The viscosity of Dexron 6 drops from 36 to 30 on cold starts and a little when warmed up as well. All while delivering better shifting and better protection during hot operation.
Bottom line is longer clutch life, quicker shifts, improved fuel economy and more HP put to the ground.

so i should be fine with this dex 6 and not switch to synthetic dex 3? alright, thanks a lot man - very informative too. i was worried i would eff up my tranny, its already at 93k god knows its fragile without me ******* anything else up


thanks. +rep

 

dex 6 do it

 

some good info, been meaning to do a flush on my tranny, and was curious as to what fluid i should use

 

Just did a bunch of research at the dealer today and we came up with Dexron VI ATF fluid as being the fluid to use for my 2008 2.4L Sport 5-speed manual. Bought the AC Delco stuff they had in stock ($15 for 2L). Gonna save a lot of money doing this myself!
Anyone having any problems with this fluid btw? its good to know for the future...

 

i've been using the mtf for the ss/sc transmissions. my car absolutely loves it.
