I'm posting some pics of (I think) my bw11 on my 71 800B. The shifter is a non-stock B&M shifter thats been adapted to the transmission tunnel cover, so I'm wondering if my linkage is standard.

I've attached a pic of where it is screwed to the tunnel cover/shifter, and where it goes up through the firewall.

Not sure if you are asking a question or not michael!

There is some bw 11 info in this thread...in this sub-forum, the first pic shows an oem shifter unit:

The one pic you posted shows the "tranny cooler" which is actually a marine-type heat exchanger that was plumbed in for the s800 and some pickups and t'alls equipped with the bw tranny. Many pickups never had a tranny cooler and you will see those trannys with the cooler inlet and outlet "looped" with a piece of formed tubing that is oem. The torque converters on these units are referred to as "air cooled" and includes a fan assembly on it's periphery.
 
Thanks michael - yes, that photo in the thread you referenced seems to show a physical shifter linkage on the drivers side of the tranny. Mine:

Just has a cable running from a linkage which attaches to a B&M shifter that was bolted on the tunnel cover, and then snakes up past the firewall:

I guess I'm asking if this is just "another way of doing things" or an obvious po mod? And if it is a mod, is it something to be 'fixed' or something to be 'kept'?

If you can't tell anything from these pics, I'll try to get some better ones tonight. Gracias.
 
If the current shifter setup indexes the shift lever correctly on the transmission, and it functions correctly (the tranny), then that setup should be just fine!

In fact, I'm surprised we don't see more aftermarket shifter workarounds (either hurst, speedway, B&M, lokar, etc.) for this kinda stuff.

But the back up light actuation, nss actuation, and kickdown actuation on the bw trannys is entirely different from the torqueflite 727 stuff used on later IH apps, so don't let the discussions regarding those confuse ya, we're talkin' two entirely different transmission setups here! And the bw 11 requires a functional vacuum connection to it's "modulator" component, so that is always a problematic "vacuum leak" point on this old stuff when the po virus has struck!

The torqueflite tranny requires no vacuum interaction at all, so again, ya can't compare apples and oranges on these Scout autotrannys.
