I have used Valvoline Dexron VI in my transmission. Over 3000 miles now and no issues either with easy driving or hammering it. I have a writeup somewhere on here on doing it, just not with pictures. I will try to find it and edit my post.

Here is the procedure:
I ordered the kit from ECS Tuning. It was an original BMW kit. It was about $50 more than the Elring Klinger one but there was a rumor floating around that the design wasn't quite the same as in it didn't have the pickup on the bottom of the filter. Based on the pictures on ECS Tuning's site of the Erling Klinger one, it would appear that it looks just like the OEM one. I've always been weary of transmission problems so I just bit the bullet and got the OE one to alleviate my paranoia.

The OE one, as you would expect, fit great. It also came with new pan bolts and the original metal gasket with the rubber sealing edge.

The fluid I used was Valvoline DEX VI from Napa. Dealer says the Texaco stuff was superceded by this. I'd call up 2 different dealers and confirm using your VIN.

It's also on this board somewhere but basically what you do is:

1. Warm up the fluid a bit by taking the car on a quick drive, maybe 10 minutes round-trip.

2. Open the fill bolt first and leave it in, loosely.

3. Open the drain bolt and let it all drain out. [Marvel in the fact that the fluid you're watching pour out was once bright red.]

4. Once it's all drained, re-tighten the drain bolt and start pumping new fluid in. It should take about 4 quarts, roughly, until the fluid starts backing/spilling out the fill hole. Also, unless you're working with your car on a lift, the minimal clearance ramps or jack stands get you will warrant a proper hand pump that secures to the top of the bottle of fluid. You might not even need to raise the car, I didn't - not for this part.

5. Close up the fill bolt and return the car to the ground. Take it out for another spin but this time, take it easy on the tranny but take a little longer, maybe aboutt 15-20 mins roundtrip.

6. Return and drain all the fluid out again. It will probably still be almost as dark as it was the 1st time. What you're doing is diluting the old fluid left in the trans cooler lines and torque converter.

7. Undo the pan bolts. On my '06, I had to undo a part of the exhaust hanger/support to get to 1 bolt. Just loosen it and your ratchet extension should slip between.

8. Remove the pan, gasket and old filter. Remove the filter by pulling gently downwards. Don't try to flex it in any direction other than down or it may break. When you pull the filter out, there should be 2 separate ribbed o-rings on the neck of the filter. If there's only 1, the other is stuck in the opening of the transmission itself. I used a tiny flat bladed screw driver, pressed it into the inside of the o-ring, applied pressure and pulled down. Try not to score or scratch the transmission housing.

9. Clean out the pan with some lint free shop towels [the blue ones]. Get all the gunk off of the magnet [you can pull it off] and avoid dropping it anywhere else but the pan.

10. Lube up the o-rings and neck on the new filter with the new ATF and insert into the transmission body. Light to moderate force may be required to push it up. Push directly under the neck of the filter on the underside facing the ground.

11. Apply some ATF with your finger around the rim of the newly-cleaned pan lightly and seat the gasket.

12. Secure the pan to the transmission. [I recall that being alot harder that this sounds when I did it without a helping hand]. This is the fun part. Keep telling yourself that. Using the new bolts, secure two on opposite ends to free up your hand. Then go around in a linear fashion and lightly tighten the bolts working your way around the pan.

13. Torque the bolts down to spec. I forget what the spec is at this time [sorry]. But it is important that they all be torqued equally.

14. Start pumping new fluid in. Again, it should take about 4 quarts.

15. Close up the fill bolt and start the truck up. Run it through the gears slowly, pausing in between each. I even kicked it over to sport mode and went through it manually but I couldn't get higher than 3rd since I wasn't moving.

16. Shut it off. Get back under, open the fill bolt and top up with an additional 2.5 quarts, roughly.

Close it up, clean up and go for a drive!

Check the level again in about a week to make sure it's at the proper level. If fluid spills out or is just under the treaded portion of the fill hole, you're good. Traditionally, it should be checked with the transmission lukewarm so be careful not to get burned by the exhaust or anything.
