So I did a tune up (75,000 miles) on my 06 2.4 today. Plugs, fuel filter, air filter, cabin filter, oil filter/change. I used AC Delco Iridium plugs, then always use Mobil 1 oil and Wix filters. So now on to my transmission, I got a Wix filter but not sure what fluid to run. Should I run AC Delco Dexron VI or should I go with Castrol or Valvoline Full Synthetic Dexron VI? Just wanted to get some input before changing tranny fluid. Also best place to buy/order?

Thanks!

 

You can run delco, but I would use valvoline; It will meet all specifications, and should be cheaper than the delco stuff.

Never run castrol anything in any of your vehicles

 

why not?^

 

I ran castrol for about 25k in my 2.2, untill I got a leaking axle seal.
I refilled with amsoil.

 

I used valvoline full synthetic in mine.

 

Did you guys just drop the pan, change filter and put the 5-6 quarts in? Or try to get the rest of the fluid out through trans cooler line?

 

Ah your auto...
The majority of old fluid left in the system is in the torque converter.

The best way to get everything out of the system is a quality trans flush machine.

 

Ya I realize that but rather not do a flush. Always hear bad bad things about problems after flush because of the pressure. I don't like doing things that require me to sign something saying they are not responsible if anything happens lol.

 

Do you know what they want you to sign? If its liability paperwork just for trans flush,I wouldn't sign anything like that...you would prolly be better off taking it to a dealer or try a more reputable shop
The only paperwork my shop requires signature on is the work order approving the work to get done.

Thats a common misconception; Transmission flush machines use the trans pump(vehicle running in park or neutral).
What happens is; You hook the flush machine in line(usually by cooler), start the car, get to operating temperature, then flip the flush machine from bypass to transfer.
The old transmission fluid goes into a container with a bladder inside(all inside flush machine) and as the old fluid(bladder)builds volume it begins to push the new fluid on the other side of the bladder which then goes into the cooler. After about 20minutes, You will see a pressure drop on one side and raise of pressure; The flush is done, remove the flush machine and test drive

 

my .02

when i did mine @ 100k km /60 k miles i used the GM delco stuff, F23 5 speed, not auto though.

Canada can turn a man into a woman with how cold our winters get, so alot performance/branded oils can freeze up in the winter

 

I got a 5spd not auto. So for me it's just like changing the engine oil, pull plug empty and refill. I have no clue as of how to do a fluid change/flush for an automatic car, never owned one.

 

^******' Man-mode response!

 

Only reason im proficient with a trans flush is that I make 120$ for 2 minutes of work out of the 20minutes(ish) it takes to do the job. The rest of the time, I just watch the feed and return gauges until I see the correct readings.

 

^ROFL --- so ******* win, thats 120$ more to the motor for connecting hoses and waiting!

 

Lol, ya forgot to mention it's a auto. Takes 12.9 quarts total and only about half drops from the pan. So either take it somewhere to get flushed or try disconnect trans cooler line to get the fluid out of torque converter or just replace half and filter...

 

If you were very persistent, you could do it yourself and have a buddy for help(or 3)
You can get a few gallons of tranny fluid and a bunch of line.

Run 1 line from a bucket of new fluid to trans and the outlet to an empty bucket; run the car and when you start seeing new fluid, shut off and reconnect

 

^ ******' smart

gonna steal that one for the future! you aint getting 120$ out me now Verbatim!!!!!

 

Thats a lot of work for nothing.

Just drop pan and change fluid and filter that comes from pan.

If youre **** then park the car overnight and dont start or move it and the converter fluid will be in the pan.
