Hi all, Currently working on my 190, I've started ordering parts for my M104 to get the desired 1000HP. If anyone is familiar with the M104 the go to gearbox is a 722.6 automatic as it can handle the torque. I've bought a 717.460 manual box from the C230 Kompressor but I highly doubt the gears will take the 1000HP. I'm not really wanting to go down the route of adaptor plates etc so if the manual shits itself I'll purchase a 722.6 box and buy the aftermarket ECU to convert to a manually shifting auto. My questions being even though I can manually hold the gears, what will be the problems when I pull the Hydro locking up the rear? Will the fuck the gearbox quick? Many thanks
