Hi All,

Just hit 100,000 miles.

What AT fluid can be used with our 335d. tischer bmw unfortunately does not ship this item.

Thanks,

Roger

This is what you can use:

Are you going to change the pan and filter too?

Thanks bro!!!

24152333903 $194.25 - in stock oil pan/ filter. OMG!!!


How many liters do I need. I am going to find an Indy to do the work.

No problem man. I've heard at minimum you'll need 4L but I'd ask the indy shop too. I'd figure 4-6L.

I'd do fluid flush with pan and filter.

Roger, most of us here wouldn't recommend waiting until 100,000 miles. A couple guys took a picture of their fluid when coming out at 80 or 90 thousand and it was black. Nothing to do with BMW transmissions, my general recipe is to change at no later than 50,000 miles. My theory is 2 fold. I would want the fluid to come out before it starts to turn color. 2nd part is if you change twice as often and only do a drain and fill, it sort of equates to a drain, flush and fill and 2 changes at 50k and 100k, respectively. If all you do is a drain, you don't get the old fluid out of the torque converter. I'm not a fan of flushing a transmission.

My advice since you went 100,000 is NOT to have it flushed. You are runnning the risk of breaking small particles loose and possibly clogging a valve or orifice elsewhere in transmission especially with very high miles fluid.

Some mechanics say if you let the fluid go too far, it is best to leave it alone as it may have issues with the new fluid causing it to slip.

damn bro - you got yours like 6mo after me and I'm only @ 40k!

Yep. 120 miles roundtrip daily from feb 2011 to dec 2013. Bmwna gave me a new engine and dde at 80k, runs great.

Plan to do my check soon at 50k but will venture out with AMSOIL or Shaeffer

I was going to type the same but I'll just throw in a "I second this" here.

I wouldn't be surprised to see you have additional issues after changing the fluid and filter. You either get the car on a proper, more intensive maintenance regiment than BMW's early on or you just stick with what you've been doing.

Had this EXACT discussion with my SA last time I was in for service. I'm approaching 46,000 miles so I'm going to change the fluid next time I'm at my father's shop in FL. My SA and I were talking about people servicing the transmissions for the first time after 100,000 miles and how many he's seen have transmission failures just after service. I wouldn't take that bet if, you have nothing wrong currently, let it go.

For what its worth, I'm fairly certain mine took 5.5 qts. You have to follow the refill procedure correctly or you might only get like 3 qts in there.

Also, the black fluid measurement doesn't really apply. According to zf the fluid oxidizes to black while in the trans, from the sound of it all fluid older than a couple months would come out black.

How many miles before you changed yours? Man all these posts have me doubting if I should change it out.

Can someone clarify on the fluid change, i.e., when I spoke to a very reputable indy he said that if you change out the pan you still won't be draining all of the fluid out of the transmission. More specifically he said that even with swapping in a new pan you will only drain 1/3 to 1/4 of the fluid from the transmission. If this is the case, why do it?

[Hoooper]

There is a lot of fluid in the trans and torque converter that doesn't drain. You still do the change because a new filter and some new fluid is better than an old dirty filter and old fluid

Adding to Hooper's thoughts. My thought is to change every 35 to40,000 miles taking into account that not all of the fluid is drained (torque converter is main culprit). Also, the flow paths between the trans and the fluid cooler up close to radiator (atleast for my dodge truck). I've done a change at 35k and 70k on the truck. That change at 70k had fairly good looking fluid come out so the torque converters non change didn't hurt me. NOTE: that is for ATF+4 fluid not the Longlife 6 that we use on the transmission under discussion.

Without going into powerflush mode, i've read there is away to cycle fluid through the torque converter. Something about sucking fresh fluid out of a full bucket and letting old fluid come out into empty bucket on opposite end. You do this until you see clean fresh fluid going into "dirty fluid" bucket. I have no clue if this would work on the ZF trans though. If ZF has the external cooler, there would be a decent chance. I will research and report back.
