Have this weird issue from take off. Only happens right after i warm up the car and go. Disappears after ive been driving for a bit. It has a violent bucking/jerky take off. Not sure if its trans related or not.
One thing i tried was the tcu reset and it doesnt happen. but after ive been driving for a few days it comes back. I have checked the gap from blower pulley and its good. Not sure what to make of it. Have any of you experience this type of issue?

How violent are we talking about?

Could be mount-related, but I would be surprised since it is temperature-variable.
Have you changed your trans and/or diff fluids recently. If not, I would check levels and start there

Does it happen between gear changes at low speed (around10 mph or so) light throttle only when cold? If so it probably is the TCC solenoid.

Drive it in manual mode and see if you feel it either while you're in one gear or when you shift. Check trans level, scan TCU for faults, look at TCU wire harness for fluid intrusion.

I agree it could be TCC solenoid, I had mine go bad a few years back with similar symptoms. You'll want to look for codes though as conductor plates can go bad too and the job requires you remove both.

If the engine is running well I'd be less concerned about a tune or vacuum type issue, but if you haven't checked your fuel trims lately I'd do that too.

Trans been rebuilt 2 years ago from Sun Valley mercedes transmission.

Are you stock? Are you on a clutched pulley? The bucking happens because of the clutch engagement, the temperature should not have an affect on that (I have owned three E55s and all did this; my indy that has been working on AMG cars for decades says it is completely normal and I agree with him).
All V8 Kompressor AMG cars have this happen depending on throttle play. Mine smoothed out a bit with the EuroCharged tune but it is still there, just not as violent as stock.
I am running a clutched 83mm upper. No issues with my stock blower pulley either, it was in excellent shape when removed and the gapping was/is perfect with both stock and 83mm.

My car is not stock. 180 lower and stock upper, 82mm tb and mbh headers. Tcu tune as well.

I hate to say it, but I think I experienced this when I had the 82mm TB...I'd try a TB reset (I can't remember but it's something like unplug it, key on, plug it back in and wait etc, search should bring it up). If the TCU (I'm assuming 'sneaky') reset helps it for a short period of time, that can be another indicator since the reset just re-pairs the TB, accelerator inputs, and shift points all together. Watch your fuel trims when it acts up too.

Larger TB--- I would definitely start there for diagnosing, as everything you said in your original post now makes more sense. I know many E55 guys that have a nightmares with their TBs while others running smooth as silk. Hit or miss, really.

I had a problem with a bluetop shift solenoid. It was very weird though coz only symptom was first cold shift in c mode would delay the shift and then shift mega hard giving big jerk and causing huge supercharger belt slip chirp. All other driving modes would never happen probably coz 2nd to third solenoid and all other shifts would be fine after that first one ****ed. Kinda felt like the solenoid would jam and the pressure build up would help it open the first time and normal operation would last until next cooldown.

So a bad solenoid in the VB could cause your problem as well as conductor plate or other VB related issues.

Did the rebuild include the VB or was it just the box internals?

Don't have experience with TB stayed away coz of the bad press.
