So I'm about to start a new project. A build that has never been done. I need some feedback on my question that will appear at the end of this ramble.
I run a 42RE transmission behind a 4.0L. For those unfamiliar it is a 4 speed trans. That uses an overdrive unit in a separate extension housing on the rear of the trans. Just like all of the 46-47-48REs that most are used to. Just a smaller scale. All of the same internal designs.
I'm going to remove the overdrive unit along with the entire housing and adapt a front case half of another tcase in its place. No worries on fluid passage issues or on how to adapt the tcase to the trans.
One of my biggest concerns is when I eliminate the overdrive unit I also lose my OEM parking linkage and pawl. So that leaves me with no park position.
I'm 100% out on a prop shaft brake unless it's invisible.
My main question is are there any recommendations on how to create a park function? Whether it be a mechanical out of the box idea or a single piston master cylinder that only applies the rear brakes with a ratcheting handle? Has anyone ever done this before personally? Creating a parking brake that they felt safe enough to walk away from on a sketchy climb?
Would love pics or links of extraordinary ideas. Thanks guys
