Looks great!,
Only i hate the M46 (4 gears with overdrive), My M46 was almost completely rebuild( i still feel the pain in my wallet) and after almost 5000 kilometers i had no overdrive anymore
,
The second M46 was also a complete disaster,
Now i have the M90 from a 945 TDic from 1996 and already driven almost 50.000 kilometers only with a oil change and it is still going strong every day again without any problems.
But i wish you wont have those problems that i had with that gearbox and that you may drive with a huge smile on your face!
