wasn’t exactly sure where this should go… ![http://img.photobucket.com/albums/v516/ctnewman2/transfercase.gif](http://img.photobucket.com/albums/v516/ctnewman2/transfercase.gif) it’s on the front of the transfer case… i’m still kicking around the idea of cutting that off… I don’t really care about the mass, but the space it occupies will make exhaust routing a bit trickier… I doubt it is for the attessa actuator, because there is a pump for that on the pumpkin… The only thing i can think of is to keep the oil level in the lower portion of the transfer case from getting too high… thoughts? ---

How much could you get for an RB26 trans? Maybe contemplate selling for an RB25 or call mickinney and see if they will trade? ---

cut it off, see what happens, if something goes wrong another tranny will only cost u $200 and you have to do a bit of exhuast rerouting edit: that t-case shouldnt be nohtin’ to you ---

so this transfer case has a oil pump on the mt model rather than the auto tranny pump circulating the fluid? ---

if you have a factory manual (which it appears you do) does it not show a fluid graph for the transmission? You know, as it would with an auto so you know exactly what the fluid is doing while it’s inside of said transfer case? ---

i’ve seen that, but they were also a bunch of hacks… the way the transmission is put together is not conducive to welding a plate on. I am going to machine the diff off and then bolt on a plate. If i weld it, i can never change any of the bearings on the inside… especially the output flange bearing ---

I am going to machine the diff off and then bolt on a plate. If i weld it, i can never change any of the bearings on the inside… especially the output flange bearing oh i agree 100% with that considering you have the means to do it very cleanly. but judging from the way they did it , it would lead one to believe that that pump/chain will not be necessary or a worry whatsoever.
