1st gear hard shift in D

Hi guys, first post in this forum. I have a '06 325i 4door. When coming to a stop, the transmission waits until the car is almost completely stopped and then shifts hard into first gear. Shifting up or down through all other gears is creamy smooth, hard shift does not happen when using the manual shift. If I shift into neutral and then back into D it shifts smoother, whether stopped or rolling. This condition is less noticeable while cold, but becomes harsh as the vehicle warms up. Also seems to be smoother when going uphill, but down hill and level feel the same. I've tried braking hard, soft, and coasting to a stop, but it made no difference. Also there is a slight hesitation when shifting to reverse. My first thought is low fluid. How do I check fluid level? If that is not it, what else might you suggest? Thank you all

Maybe i'm way off, but the car "remembers" how you drive. Did you try resetting the gearbox(throttle adaptation)?

Is there a way to make a definitive diagnosis of that?

Skip that step you can't do it without software no matter what people will tell you.

Get your transmission fluid and filter changed + Mechatronic sealing sleeve you will need about 5.5L of fluid, use only ZF Lifeguard 6 if your transmission is ZF if it's GM any DEXRON VI is fine.

If this doesn't fix it, next step will be the transmission solenoids.

1st gear hard shift in D

I'm not going to bash on bmw, but I really think they messed up on the new update. Since I got the update I've noticed my car will start in first, where it normally was second. Downshift into first going to a redlight etc.. and the most unusual thing I've noticed was my car going into neutral (NIC) a lot more than usual.

.

Whelp, how many miles since last transmission fluid change? Whazzat?? NEVER??? Then [click here]

And even if it has been changed within last 50k mi, [do this] assuming you got one, which I don't not never know, being unfamiliar w/your engine config.

BUT before any o'that:

[click here]

Say, GM transmission?

You can't really diagnose seals in the trans without physically inspecting them.

The solenoids, if they are bad enough, will store shadow fault codes in the EGS module.

The "adaptive" driving profile is not as "adaptive" as people think it is. There are a few preconfigured driving profiles stored within the car. Depending on how you drive, different profiles will be activated. It does not really store unique shifting behavior for each driver. Resetting this will not help with the 2-1 shift, which is a common issue with the ZF 6HPxx transmissions.

I did the KOEO 30s flat throttle. It shifts smoothly some times and harsh others. Any thoughts?

Yeah. I found some instructions that said
Put in key
Without pressing brake to start engine, only press the On/Off button to turn on the power
Hold throttle all the way down for 30 seconds, may hear a chime(I didn't hear any noise)
Press On/Off button to turn off power
Start engine and drive normally.
I did that and it shifts better some times.
