I have about 108,000 miles on my monte. And I think its time to change the transmission fluid. I don't have my manual that came with the car. So what kind of transmission fluid and how many(quarts)? Thanks.

 

What transmission do you have? The 4T65e? If so then you need 8 quarts of dextron III. It takes like 7.5 quarts with just a pan drain and filter change. It takes more if you drain the converter but I dont know how much that is.

 

My bad.. The only thing I can tell you is, its a 2003 ls 3.4

 

4T60 E i think is waht you have hten...

 

If I remember correctly the 3.4l engines had the 4t65e behind them. Someone correct me if Im wrong.
