I would like to change my transmission fluid. I read the how to and it says to use DEXRON ATF III, The problem is all the DEXRON ATF III that I have found says for automatic transmissions PLease let me know what I can use, I have a
2006 Cobalt LS manual transmission, which I believe is the F23 transmission. Thanks for your help and if you want to post a pic. even better.

 

Your best bet is to call the dealers parts department and ask them what fluid it takes

 

Do you not have an owners manual?
