Well im on 20k miles her ein a few months. time for a trans flush. tech says 12 quarts for a full flush and the machine lets the trans pump new fluid in and old fluid out into collection tank. if i do amsoil that a lot of $$$$$$. is the Gm automatic fluid THAT bad that it would be worth doing a amsoil swap.. i get 1/2 off all service so my trans flush cost 100$

Drop and fill never flush.

Perhaps Amsoil is better, or perhaps not. Even if it is, simply following the recommended maintenance using the correct fluid is plenty good enough. The exception for me would be the so-called "lifetime fills". That's a rule just meant to be broken.

and why is that? this is a flush with trans pump method now a power flush. done by my dealer at 20k miles

yah i figure even if its not the best if i flush every 20-25k it should be ok

I've heard that the flush machines are used on multiple cars that take different fluids, and that there is always some residual fluid in there. The wrong fluid, even a little bit, can be a big problem.

This is a bit scary, but looks potentially effective. It's not for the Cruze, but the same concept could apply. I am not recommending it, just posting it as an example of what someone has done.

Assuming you meant 'drain and fill', I have no problem with this strategy, either. Yeah, you'll only get half the fluid out, but it's quick and easy and if you do it within the maintenance interval, the fluid will stay plenty clean.
It's when the oil is left in tens of thousands of miles past the recommended interval that a flush might start to make sense.

reason i ask is that its being done at a dealership.. by a dealer teck... and im under power train with a long time to go. if it does blow up thats fine since i have all paperwork proving dealership did all the service

If they are using the cooling lines and bucket method its fine any sort of power flush breaks things. so I'm told by employed Mechanics in the family that I trust.

At our dealer we dont use a power flusher. Its basically snaps onto rad trans lines, has a 2 massive reservoirs one with 12qt new and empty old. Turn the machine and car on and let the trans do its thing. Most new places get rid of power flushers due to high bring back rate

Check your owners manual for the service interval. The only thing that a drain/fill of the ATF at 20K miles will do is drain your wallet and fill the dealerships wallet.

GM's transmission fluid, Dexron VI, is excellent.

The problem is that the diesel transmission is made by Aisin and takes Aisin AW-1 fluid. I dint know anything about that fluid.

When the time comes I will go with Amsoil Signature Series ATF in my diesel transmission.

 

[pandrad61]

Its starting to get rough on down shifts so i may just take it in for a warranty diag. my manual under severe says 35k if i remember. todya they replaced my seat track since it pivoted excessively and squeaked

thats why i ask. ive had old gm trans and they are amazingly stout in general and fluid good but this being a non gm plant i want to make sure its ok. ill have them do a diag some time next week.. i would love signature series but expensive for 12qt lol

i thought the amsoil was less expensive than the ~$20 a quart for the aw1

Maybe there is a problem with your transmission? Mine shifts fine at 17k. I think the fluid that tomko said is in our CTD transmission is more expensive than amsoil. If I still own the car will prolly change at 40-50k miles, have not determined what I will use just yet.

not sure. figure 12qt x20 =240$ not shipped plus the small small labor fee

I do not understand why you are wanting to change or flush the fluid at only 20,000 miles??? As far as I can see there is no maintenance recommendations at at at a 20,000 mile interval and the earliest I could see for the trans fluid was 45,000 miles. If you really want to throw money away, I'll send you my paypal info!

possibly yes. on down shifts when slowing from 50 around 4-3 3-2 it jerks on the down shift and not a fan,, occasional but enough to concern me. plus this car will stay with me for 25 years sinc ei bought it brand new so im ok with a initial early procedure and maybe get it analyzed if possible to see how oem fluid does with my driving habits and location

i mya have a tech look at it and see what he thinks but a early sample at 20k to see how it holds up wouldn't be bad, plus then i know its done with better fluid. im a very hard driver..either way back to my original question.. Is the fluid in the CTD really all that bad to have it break down before sever flush interval or would it make it?
