I don't think it is a size thing, it is how you hold your foot. While I am not what I once was I can still do squat work sets at 315. Getting old sucks, better than the alternative though.Some of you need to bulk up!
There is no reason to lift your foot from the accelerator when shifting! Keep the accelerator pinned to the floor the whole way through or at least as far as safety allows.
Didn't mean to imply I'm manually shifting. It's an auto. If I don't do this my foot bounces off the pedal.
I realize it’s an auto. You still don’t want to lift your foot after you shift then slam it back down again. That is why it’s bouncing and jerking!
Yeah, actually that's not what makes it jerk. That's what stops it from jerking. It works for me. Definitely not a permenant solution. But, it's something I've found that keeps my foot from bouncing off the pedal, because my foots already off the pedal. I know I have to come up with a better solution.
I have tried this as well when at the track, road course, in Track mode. The jerking was not helped by completely letting off of gas, just created jerking from gear change under engine braking. I just give it neutral amount of gas before engine braking occurs. Problem I have is late in a session trans gets sluggish when hot. I was taking a slow turn onto straight and requires multiple gears to be downshifted, it was shifting slow and thought maybe I didn’t downshift to right gear, hit the paddle one more time began to accelerate into straight out of turn and it went down 2 instead of 1 gear and I lit the tires up and had to catch it before meeting a tire wall. Not predictable based on inputs when hot. Had a BMW 335i before and loved the car more after flashing the trans with Alpina flash. Was able to floor it and shift and the shift was so fast I did not have to worry about sluggish jerky shifts. Is there a trans tune out there that sorts these issues? I know it won’t last as long but at least it will be predictable. Trans replacement sooner is prob cheaper than repairs after wrecking.
Glad I found this thread and that it’s not just my car. My trans does this exact same thing. Best solution I’ve found so far is to drive around a bit in Normal mode before switching over to Sport. It seems better after the car has warmed up a bit.
Pretty sure he means software updates in the ECU not the infotainment.
I just had the dealership do a full Kam reset on my 2019. I did not realize there is a whole process to go through after the Kam reset. I am sure a lot of people know this but I did not. I did a Kam reset on my own without going through the steps afterwards and it had zero effect on the trans shifting characteristics. Since the dealer reset the Kam and correctly went through the on road steps, my trans has smoothed out quite a bit. Hope that helps someone!
I’ve seen the steps and they seem like a giant pain in the ass to do. But I suppose I should try them before having the dealership mess with it. I don’t have the digital dash so I’m not sure if there is a way to tell what gear I’m in. Also would need to find an abandoned stretch of road out in the country to do this lol.
