My friend just got a 328i and I was with him on some backroads
When he was trying out the sport shift.

Somehow when he was crawling to a stop maybe at 10km/hr he accidently
Put the car in R. We didn’t hear any weird noises or anything and
The car shifts fine. Did he do any damage? I’m surprised the
Car let’s you shift into R while moving. The car has an auto trans

We tried all the gears and reverse and everything seems perfect

Most likely it’s fine. BMW accounted for idiots doing stuff like this.

Cool, I wonder if there is a note specifically for the g.m. Trans in some literature

did the car jolt? The premise of the no damage in the article seems to be that the vehicle ignores the request. I could see that in the case where a transmission lever is connected to a switch, not the tranny. Since my car is a stick I don't know if that's the case or not, and obviously I've never tried it in a loaner.

I doubt it even went into gear, it should be locked out unless you're stopped. I wouldn't worry about it.

Funny thing, I did this in drivers ed to the school car. It was some 80's GM shitbox. It DID go into gear and the car lurched to a stop post-haste. I don't think I broke it, but the instructor did not find it nearly as funny as we did.

So safe to teach driving in too, it barely had enough power to merge on the freeway with the instructor and 3 students in the car. lol.

the gm transmission is still controlled mechanically for P/R/D.
the only thing electronically controlled is the solenoids that make it shift.

This is why the GM and ZF shifters are wildly different in the car.

at 10KMH it probably didn't do harm. your friend needs to stop depressing the button when using the sport shift. If you don't depress the button the shift gate will stop it from going passed neutral if he were to make the same mistake again.

so don't squeeze it. it will move freely in the manual shift gate withut doing anything, and at that point the electronics will keep it from shifting into a gear that will over rev the motor or do damage.

I tried to duplicate it in a parking lot, if you keep your foot off the brake it locks the shifter from going into R. He must have had his foot on brake. He’s still freaking out, I drove his car and it drive fine.

If you press the brake it’s not locked out. I did the same thing with my Dads
1980 Olds Tornado when the brakes failed. Made some nasty noise but was okay.

I scanned his car for codes but none were present.
I tried connecting to the trans through INPA but it wouldn’t
Let me. I tried with my car and had the same issue, it gave me errors.
