I think I had about 3qts, but could have even been a little less. I could hear it suck air before I could get more fluid in, due to the poor handpump situation. I have not taken the car on the highway yet, so I assume it will go away once I get it up to speed as others have reported. I will check that the car is level next time, or even tilt forward a little.
I just changed the ATF/filter on my 07 328xi, and am experiencing the same ticking, did yours ever resolve?

I am thinking of putting mine up on jack stands again and rechecking the fluid level.... I filled mine and checked at 86 degrees, so I thought I'd be good. Ticked at first, then seemed to go away...been driving a few hundred miles, and at idle I can now hear a faint ticking or clicking every second or two still if I get under the car. Definitely sounds like metal on metal. Thinking maybe its that arm with the roller bearing on it under the manual selector lever, or something of a similar composition.

Not sure if perhaps these cars make a faint tick in that area. May try to take a look at other 328xi's to see if perhaps they all sound like this, again can't hear it unless you get under the car...Hmm.


Here is a vid of the sound, its the single metallic tap every second and a half or so :




Anyone have any thoughts?

A couple people in the thread said they had a tick for a little while afterwards. But all I saw had said it went away with time. YMMV. IF you topped off the ATF properly, there really isn't much more you can do. You could drain and replace again, and possibly put in the TCC additive. Because the next step is a bit invasive....

Thanks Bluewater - I will check the level, and hope that's the issue. If not, I guess I dislodged something that is now stuck and clogging the valve body somewhere. Hope that's not what it is, or at least hope that it resolves itself before destroying my transmission.

Ordered the lubeguard products, but I really hope to resolve this without resorting to mechanic in a bottle "fixes".

Wish I had the patience to drop the valve body and clean all the passages, if that is in fact what's going on....hopefully the fluid level somehow read correctly when it was not in fact correct.

Thanks for the advice.

1. Yes, the filter needs to be serviced, the dump drain, and refill method just isn't enough. As the filter plugs up, the line pressure in the trans goes down, and friction material wear increases.

2 .Dex VI is one on the worst fluids GM ever came up with. It was mandated to meet a ultra low viscosity requirement from the upper brass, to try to raise fuel economy of the GM fleet. Its not known for good shifts, or prolonging transmission life. I own several GM products in my personal life, as well as the company I own. The first thing I do when adding a vehicle is dump out that DEX VI.

So, what to use then?

Allison Transmissions (a division of GM) had Castrol invent a "Super Dex VI" to address the shortcomings of DEX VI, and boy did they deliver! The fluid is known as "Transynd", and carries the identifier TES-295. Several companies make a licensed version, they are listed here.

http://www.allisontransmission.com/p...highway-fluids

Here's how I service a GM / DEX VI transmission.

1. Drain pan, remove pan, replace filter, install pan.
2. Fill with a TES-295 fluid ( I use Mobil Delvac) Get the level close, but you dont need to be exact. Run the car for about 5 minutes and then drain the pan again. ( no need to drop the pan, just drain it) This is known as a "Double Dump" and will swap out about 90+% of the fluid. Now refill it again, and do spend the time to get the temp up, and set the fluid level accurately.

And that's it. This fluid is designed to go a minimum of 100,000 miles, in city buses, dump trucks, and other HIGHLY stressed applications where DEX VI would fail in no time.

For anyone wanting more info on TES-295 fluids, here is good read directly from Allison:

"When using Allison Lube spec TES 295 fluid, change intervals should be as follows:
Fluid life: 150,000 miles / 6,000 hours
Lube/Auxiliary Filter (if used): 75,000 miles / 3,000 hours
Internal Filter : Changed only during transmission overhauls
Initial 10,000 mile change:Not required with TES 295 fluids

Using any oil not listed as TES 295 approved or a non-Allison genuine filter may void your warranty.
Also note that effective January 2010, per Allison Service TIP 1099N, Allison no longer authorizes the use of DEXRONŽ III or IV in any of its transmissions."

As always, do your own research, but I've yet to have ANY transmission issues since switching everything over to a TES-295 fluid.

I'm surprized no one has either commented or followed up with their own experiences with switching over to a TES 295 fluid. It's been 20k miles, and my trans has never shifted better.....

So I bought this as well, and MAN, is that a whole lot longer than the stock plug. After seeing the pan drop, I don't think anything is close, but it's a good amount taller than the stock plug...albiet, at least this one won't require a easy-out bit. Picture doesn't do it justice...it looks a lot bigger in person.

Not to revive a thread from the dead, but for consistency. Changed my Trans fluid at 123k miles (didn't have the car until 116k). I've done it twice now, first time I sent it off to BS for an analysis (attached). Not the greatest of news there.

I changed it because of the 40-50 MPH shudder that's common. After, I was so pissed I nearly sold it as is with the new problems. I didn't feel right about the whole thing.

I ordered the kit from FCP of course. 7 quarts of LiquiMoly 1800 (Informed them either 1100/1200 wasn't Dexron VI compatible therefore incompatible and now they don't offer it!).
1st time (10/20/18, 123450 miles). Got about 3.5 quarts out, same put in even running the car. Car had a funny noise I wasn't sure about and surged really bad in 1st and 2nd gear, drove fine on highway.

2nd time (11/17/18, 125421 miles) Only got about 1.5 quarts out. Put in over 4 (I ordered 1 extra quart from Amazon)! I did the same procedure, but this time I was a one man crew so it may have taken longer overall.

I think the sound I heard last time was the trans pump sucking air, because now there is no sound and so far I haven't had any odd noises or tranny surges in 1st and 2nd.
