| transmission is not smooth during cold start |
|
Hello again.
The forum already helped me with the stutter on my engine. now its running smooth even when its cold.
(injectors, glowplugs, oiltemperature sensor)
Now there is an other phenomenon:
already when it is "medium cold".......below around 5°C.......when I start the engine and engage reverse or drive, still idling, the car wants to start rolling, but not smoothly.....its like every second there is a "pluck" or a stutter where much more torque goes to the wheels.
Hard to describe. its Always like an impact on the engine. Idle goes down and back up, and then the next stutter. 
Like on a standard shifter car with a defect clutch.
I already flushed the ATM and changed filters and sealings. no change at all. 
This ends after maybe 50m of driving.
I'm a little bit concerned that that "impact" influences my crankshaft-lifetime.
Any ideas?
Best regards
Roland

ZF 6HP26 is showing some signs with mileages 150k and up.
Have you cleaned the mechatronic valves enabling a smooth flow of liquid?
Your phenomen could also be related to the shudder of the torque converter. Achim
