Hey guys, never driven my truck but was trying to find out what tranny I have in my '48 1/2t ,sb,deluxe,shifter in the floor. It feels like a 3 just by going through the patterns but could it be a 4? The lol I bought it from did not know . She only knew it was a straight and she didnt know how to drive a straight. Numbers or any help would be appreciated! Thanx ,Mike
