I am going nuts trying to find out about a gear swap for the crossfire.

Berg werks apparently made gears that fit but they closed down.

Any idea on where to locate used or leftover ones on a shelf?

Is there a different Mercedes model that had taller gears that would work?

Could a company like upsolute reprogram the ecu to work properly?


I have no need to go 150 mph and want to transfer some of that power down low.
I am not concerned with gas mileage.
I think this would be the single best upgrade for street driving next to forced induction, i don't have 11k for a kleenman.
