Torque converter in l322 tdv8 (Zf 6hp26)

Hi I am not able to diagnose vibration
10 different "specialists" said at least 10 different theories((TC , engine mountings, gearbox mountings etc) mountings and axles etc had been checked ...so?

What is the most common symptoms of torque converter failure ?

In my case only vibration during throttle pedal push , smaller when car is cold much worse after long ride , smth 1,2,3 changing at the higher rpm (rev) then they should (during turning or leaving the crossroads)

Please help

Vibration under light acceleration at speeds around 35-50mph, more evident on slight gradients....feels like going over a cattle grid.

Diagnostics with live data capture can show the Lock Up Clutch activity and match this against engine speeds (sometimes the rpm needle can be seen to fluctuate by a couple of hundred rpm)

It looks like TC ...simple question ...what Except TC ,filter and oil should I have to assembly gearbox after the repair ...some orings some sealant etc? Transfer box need to be take off so maybe some oring near TB???

Is it reasonable to "open" gearbox more then is required to change TC just to check other parts?

Nobody? Ok so i ordered new TC however I based only on official dealer diagnosis results which eliminated all other causes,

I hope You guys tell me one more thing

Is it any other parts which could cause vibration and its temp related? As I said vibration is not present or acceptable when car is cold or "fresh" hot (circa till 10-15 km of ride) after that getting worse

Injector faults causing a missfire.

How to check it? On the idle all injectors have the same parameters using of diagnostic ? Is it required to take computer to car and check injectors performance during ride ?

No idea, have just read that injectors can be a problem. Check other forums for vehicles that use the same engine. Google is your friend
