BLZN4FN
1/2 ton status
I'm getting ready to put the drivetrain together and was playing with the tranny.
I was able to turn by hand the input shaft (small one) But the large on I'm unale to turn by hand or with a pair of plyers the torqe converter spins freely is this normal? I can also turn the output yoke on the t-case and hear every thing turn inside of the tranny case.
I put a pic of the input that I can not move (red arrow)
