Gearbox M46 -> M47 / High RPMs on Highway...

[sonny]

Hi.

Is anyone here, who has experience to Change the Gearbox from M46 to M47 ?

I think its Plug and Play.

I want to get "rid of" the High Rpm´s Driving on the Highway....

Would it be better if i put a M47 Gearbox in ?
But anyone in my Region says, that the M47 will broke easily due the High Torque of the engine...and i should leave the M46 where it is

(thats why it only was selled with the M46 Overdrive or Automatic Tranny)

I dont want to Change the Complete Rear axle (Much work ...)
Greetings.
