Auto transmission clunk when coming to stop.

This just started today. When I'm slowing to a stop, when I get down to maybe 10 mph or so, I feel a fairly blatant clunk when the tranny shifts down from 2nd to 1st gear. It causes me & passenger to lurch forward a bit. It has never done this before. It's a 2004 330ci with about 85K miles. I've had the car for about six years and have never touched the tranny. I just asked my independent shop yesterday if I should have the fluid & filter changed, as well as the differential fluid. The answer was basically, "Wouldn't be a bad idea with almost 90K miles". I've put a few thousand bucks into the car for maintenance and wheels/tires/suspension over the last few months and after all that, I'm sick at the thought that I may have a tranny issue. Please tell me I don't!!! Any thoughts?

Thanks.

With any luck it could just be trans mounts, jack the car up & slide under. Sometimes they are so bad you can just see the damage without touching anything. Trans mounts are not expensive. IF it's inside the trans, well that's another story / price tag.


Good luck.

Do the mounts just go bad all of a sudden?

Yes.

The old rubber fatigues, then one day it just fails, as in it breaks in half. With luck, this is your problem.

If not, the price to fix it will increase.


Good luck.

Auto transmission clunk when coming to stop.

I have new tranny mounts in hand for installation, but it dawned on me that perhaps I should see how the 2nd-to-1st shift goes in sport mode. Tried it and there's no clunk. Drove it in sport mode a couple of times, then went back to normal mode. The clunk is now gone in normal mode. This is great, but I'm at a loss as to why there was a clunk. Seems as if it may be/have been a programming issue rather than anything mechanical. Stumped. Any ideas?

Change your fluid and filter. It could also be fluid level that affects that.

I've got the tranny filter & filter change on my radar, but have been stalling a bit, trying to figure out if I should buy a kit or buy the filter and fluid piecemeal.

Going to have differential fluid changed at same time. Totally unfamiliar with these fluids, hence the stalling.

Just buy the filter plus gasket and then go get your fluid.

Not many people sell a kit for tranny fluid and filter change.

Order a filter with pan gasket like ATP-B275 ( if it fits your vehicle) off Amazon for $37, and then pick up Castrol transmit import multi vehicle ATF from your local parts store

Re: Auto transmission clunk when coming to stop.

Did you also have the little gear with the ! In the middle beside your indicator on your dash?

Re: Auto transmission clunk when coming to stop.

The reason I ask is because I had this same problem in my sedan. Hard clunck when slowing down at redlight. Had the gear box warning light on dash. I had the transmission codes read by shop, nothing. One day the car finally died on me. It wouldnt do anything. Had it towed to a bmw indy shop. They told me they only thing they saw bad was the fuel pump had died and clogged fuel filter. Rrplaced both and car ran great. Never had transmission issue again. Just food for thought.
