I can see the B&M unit is physically larger, and looks beefier. Looks to be machined cylindrical steel housing instead of a cast aluminum housing as is the factory unit.
I can't see where the factory unit failed? Am I missing an obvious crack? Or did it just drop parts down into the trans?
Yes if you look at the pics in the first post, look at the pictures of the bottom of the shifter. You can see when looking at the opposite sides that parts are missing from one side. The parts were found in the bottom of the trans and it appears they took out some gears on their journey. Several of the parts are just held with a little tack weld. One builder I talked to said he welds them better on any trans he builds where the customer wants to retain the factory shifter.It looks like in post #1 the second picture the shell of the box just failed causing the parts inside to lose tolerances eventually spreading and come apart. Is that the diagnosis?
