Unknown B series transmission
Hello! I need some help!
Recently i bought a b16a swap with transmission. The guy told me that it was a ls 4.26 transmission (doesnt have any labels) and that it was grinding 3rd gear. So before installing it in the car i decided to take it to a friend that repairs tannies for a check. My friend told me that it has a 4.40 FD, so i order the synchros, springs and some sliders of a gsr since it was a "4.40" I thought it will be the same. When the parts arrived and after comparing with what the transmission actually had, it was ALL different. I was able to find some matching synchros from a synchrotech dealer which told me that the synchros i had were from a ls transmission, but i counted the teeths of my FD and it has 66 and 15, so it has a 4.40.... My question is, is it a b16 transmission or an ls with swapped FD?? How ca i tell?
