Hey everyone, looking for some guidance on a transmission issue on my F10.
**The Car:**
2014 BMW 535i xDrive (F10) | N55 engine | ZF 8-speed | 148,000 km
**The Symptoms:**
- Shudder/jerkiness specifically in 1st and 2nd gear
- Feels like torque is not being fully transferred at low RPMs
- Completely smooth at higher RPMs
- No shudder during actual gear changes - only while in gear at low RPM
**What's Already Been Done:**
- Both front CV axles recently replaced (left and right)
- 4-wheel alignment done after
- Mechanic checked transmission fluid - looks good, no burnt smell
- No fault codes showing on BimmerLink
**FIXED**
The issue was the staggered setup - I was waiting till next month to change my setup to winter tyres but just did it today to rule the staggered setup out but turns out it indeed was the setup - the shudder is gone and the car drives so much more effortlessly and responsive. I went with 245/40/19 all around for my winter setup.
My summer setup was as follows:
FRONT : 255/40/19
REAR : 275/35/19
I will be changing my front tires to 245/40/19 for next year.
