Hey guys got my tranny in and about to replace inner primary mainshaft seal and starter jack shaft seal. I noticed the mainshaft seal ( found my glasses) is stamped oil side, just to confirm this is the side that goes into primary correct? I've done this I don't know how many times and never noticed this stamped on the seal before.
For the inner primary starter jackshaft seal which way does it go? I have my service manual but for the life of me can't find this.
Thanks

 

Got it figured out and found a couple service bulletins as well, M1161 and M1148 , these explain things easily.
