Go ahead and replace the transmission fluid with AMSoil ATF fluid. Even if it has been changed you don't know what was put in there. The spark plugs are probably incorrectly gapped - most of the 2011 and 2012s had this issue. Even if they were gapped properly from the factory I discovered that my Cruze doesn't wear out spark plugs evenly.
Cruze Longevity and tuneup advice but mostly for the Auto Tran itself
hey everyone
just purchased a 2011 LTZ Auto with decent mileage 54k.
Im no tuner or into overhauling a DD fuel efficient car. But I'm all for small upgrades to get the most out of the car and increase its longevity.
I am reading after I bought the 2011 yesterday, that the Auto Transmissions can have issues, not just being 'jerky' but going out completely. Mostly it looks like international cruzes if I am not too far off with maybe the GT30 or GT35 and more with the 1.8l
My car has the GT40 transmission if I'm right, and i read that the 2011 jump to 2012 has the same transmission in USA? but it was improved for more reliability if I'm correct.
Iv also read that you cannot put a 2012 trans into a 2011 if my trans does go out on me.
Firstly, if I'm wrong somewhere, and the tranny goes out, can i put in a newer year transmission in? (without complete overhaul since with enough money you can do anything these days)
Second, I plan on changing the tranny fluid immediately with best recommended. For a start. Ill take a look at the car fax again to see if its been changed recently first.
Im also looking into a better tranny cooler. I understand its merged with the radiator? Any recommended brand or size? Keeping it as cool as possible is a good idea for any car, and this is my first automatic car iv had in 11 years of being a driver.
Im no car guy. But any stronger parts I can swap in the tranny itself (would have done by a professional of course)? Just to bolster it as preventive upgrade. If not thats fine.
Outside the transmission. Im just looking to get the best out of this car.
I hear better spark plugs are good idea especially with a tune, but even completely stock I'm seeing some experience knock anyways. regardless of octane.
Doesn't look like better injectors are needed unless you get a tune or have more done to the car. correct me if I'm wrong or efficiency can be improved.
Not looking for more horses, but anything to make run smoother and possibly more efficient.
Perhaps an intake upgrade.
I just want to keep this thing running clean cool and smooth. I owned my 99 civic til it died at 260k, and my milan at 150k til i got t-boned last month -Not injured
thank you, I've googled a lot but man its over whelming. If theres a sticky with my needs please post and thanks.
