I have a 95 f150 with an auto tranny. I was up underneath today when I seen that the Borg Warner brand was stamped into the transfer case. I'm just wondering if this is a stock t-case, orif someone upgraded along the line somewhere?

 

It's stock...they used those for quite sometime.

 

They aren t bad, I never broke one yet, so they must be unbreakable
If its manual shift its as trouble free as a 90s transfer case can be, electric ones have shift motor troubles, and if you drive fast in fourwheel drive, the chains can stretch.
I have 100k+ on mine and the only trouble i had was a snapped shifter mount.

 

Should be a 1356. Good cases. I've broken one, but no telling what my truck was put through previously. The biggest issue with them is the oil pump not staying put and therefore doesn't do it's job.
