W216 CL500 4.7L Gearbox

[Geo]

I was looking at an engine remap which will take the car to around 500bhp and add around 100nm to the torque, would any additional strain on the gearbox be a concern (7sp auto)
2012 with the 4.7 ltr turbo engine.

Isnt that the same unit as in the E/CLS63 5.5 turbo, both are seven speed but think they use a wet clutch arrangement rather than a torque converter but are otherwise internally the same box, they have 525 bhp or more as standard and plenty seem to remap them to 600 plus with torque to match so by my half arsed logic you should be fine.
