Automatic transmission fluid

I have a couple of questions for you guys about my transmission fluid. I have a 2007, 3.7L auto with a transmission cooler. Does anyone know how much fluid it takes to fill when all the fluid is drained? What is the best fluid to use? Is synthetic a good option?

Thanks.

1st you need the special dipstick,chart from '07 FSM,and a scan tool that reads the trans temp to even check the fluid level on a '07 KJ.Best just to let the dealership handle this one.

Besides that there is only 1 ATF for your trans and that is ATF+4 only.


The official list of approved ATF+4's for your trans...........

Thanks TJKJ..... was just hoping to bypass that dealer bit as they have a tendency of trying to create work for themselves and I'm not totally trusting.....

Even though I have access to the correct flush machines(at work) and can do it very cheap I choose to have the dealership flush my trans and coolant.One reason is the correct fluids are used and 2nd you get a warranty.

Just do what I do,go in and state you want a trans flush done and that is it,no inspection at all.Make it very clear to them not to even look at anything else on the vehicle,not even the air pressure in the tires as you will not buy anything or even listen to any recommendations they have.But be nice about it.

Just an update.... Checked out a few transmission and oil change shops as well as the dealer and found out that none of them want to do the flush on the transmission oil. The closest dealer won't touch it. Some shops will do it but it will cost more than the regular service and does not include the new filter.
The oil pan is also prone to rust out up here.
I have decided to use the dealer ($40 more) and will be changing the pan as it is rusting out.
Question...Does the transmission need to be reprogrammed for the shift points (dealer says they do) after a service?

Most shops,even dealerships,will not do flushes if you have higher miles with no records of a service being done before.

As far as the trans relearn it's a good thing but mainly needed for the KJ's with the 45RFE/545RFE trans,not really needed for the 42RLE which you have.

Finally Bit the bullet and went to the dealer and got my transmission service done as well as replaced the pan (rusted out).....Surprise... It actually cost less than quotedand they were very nice and even let me know that I had a licence plate light out(no charge). The great thing is they put the note on the bill and did not even suggest they fix it when I paid for the service....Bought the light and replaced it myself....Will go back for other stuff I can't do myself at least for pricing. A local transmission shop would have been $3 cheaper.... Goes to show it never hurts to shop around even at the dealers.

Keep ur eye out for harsh down shifting. If you have any you will need the re-learn. But it sounds like you got away with not needing one! mike

Thanks for the heads up but part of the service was the re-learn....So far the transmission shifts smoother that it did before
