ill keep it short and sweet.what kind of trans fluid does a 07 cobalt ls take..5 speed.i wanna swap fluids

 

use royal purple

 

ya but what type.gear oil. motor oil.dexron 3 mercon atf+4 water?lol just kiddin i need to what type!

 

i don't know that info since i am a atuo, but go to the part store ask if they got royal purple products and tell them ur make and model, thats what i do at napa,autozone etc

 

shows up na for 07. 05 comes up with dex 3 but i dont know if itchanged for 07 and i really dont wanna put the wrong **** in there

 

75w-90 gear oil

get royal purple synthetic or amsoil. when i go to order my regular motor oil from amsoil im getting their gear oil as well. i would buy 2 quarts of it but your probably only going to use like 1.75 of it.

 

okay your positive its gear oil and not dex atf?i looked up an 05 at work and it said dex3 for all trim types

 

yes, ATF stands for Automatic Transmission Fluid, which as you said you are not an automatic.


Do a search, I asked the same question a while back and you need to use 75w-90 gear oil for a 5 speed and your going to use a little under 2 quarts. and if im not mistaken, the drain for the gear oil is in the drivers side front wheel well somewhere

 

true but i have heard of standards takin atf...i mean **** the honda trannys take 10w-30

 

All transmissions in the 05-08 2.2L and 2.4L Cobalts require Dexron 3. If you go to GM they are now selling Dexron 7. Its reverse compatible. It is the proper fluid for the 5 spd getreg and the auto transmissions. It's 1.7 litres / 1.8 quarts to fill. Stick with what the manufacture reccomends.

Stu

 

bad ass cool i thought so.if i use a synthetic would that help out alot?when i shift to 2nd at high rpm it has a little grind.low rpm is smooth as a whistle and every other gear is perfect any rpm.any suggestions?

 

is the dexron that gm sells synthetic or non synthetic? if its not then im just going to stick with my plans on getting amsoil


the grinding could be bad synchros

 

started doin it with 5,000 miles i know its synchros but i dont wanna take it in yet lol maybe later on this month

 

i'd use water.

 

Word to the wise i've been down this road before if you change your trans fluid consider your warranty as far as your transmission goes voided, they won't work on it. That was one of the big questions I had to answer when i brought my car in awhile back to get the transmission fixed when i asked him what if i swapped tranny fluids the guy said well then its no longer covered.

o and i brought mine in and the tranny had to be rebuild and it had like 40 problems with it because i had to drive on it because they wouldn't take it in until it was convinent for them

 

haha lmao thats what i was thinking

 

dude.. try searching... i can't believe nobody said it already.... theres alot of posts about trans fluid and even a poll..

 

GM service info and the owners manual say for the 07 2.2 and 2.4, manual trans fluid part #88861800 which IS NOT ATF. The 05 & 06 2.2 & 2.4 take dexron 3 ATF. It was changed in 07. The 2.0 for all years takes part #21018899.

 

so the 05 and 06 MANUAL transmission cars take AUTOMATIC transmission fluid???

 

yup yup

 

its actually called mtf not atf for the manual transmission's and i just put the synthetic mtf that the ss/sc use in my 2.4L cost's a little more but worth it if you ask me.

 

do you fell diff. at all?with shifting or anything?

 

so did you end up switching yet? i just picked up some synthetic mobil 1 from autozone for $8 a quart

 

i did a little nothing huge but a little bit.
