[Silver Bullet Smart]

Hello and thank you in advance for your assistance.

Originally I was having the dreaded 3 lines of death. After replacing the clutch actuator, gear shift motor and having the new parts re-learned by a MB Star machine it went away.

However I also noticed a clunking noise when taking off from a stop.

So I replaced the motor & transmission mounts and torqued them to spec. Yet I’m still having the issue.

Any ideas?

Did you use oem mounts or generic ones?

I would get it up in the air and do the usual inspections for bearings, bushings, springs, shocks, check the crossmember, etc; doesn't cost a dime, just time.

Definitely, I’m thinking maybe bushing or something. Thank you

Do you feel the thud and clicking when you take your foot off the brake pedal?
Have you noticed if this happens on a inclined road?
Does this happen more when you are on a road that is slightly sloped downwards?
Is this on a 453 model?

On one of my 2ea. 451s I had a clunk similar to your concern. It was the right side, mid fender turn signal. Clear windshield RTV, some clear packing tape, and viola... ...fixed!

I have this issue only when the road has a small downward slope with my 2017 453. If the road is flat or upward slope, no issue at all
