Question about Input Shafts for C4
Well tore apart my t-bird this weekend and I sheared the input shaft off in the torque converter. Pulled the trans apart and put it back together to make sure there wasn't any damage but in the process I had to use an input shaft from a different trans. The new input shaft has a thinner spot in the middle but was 26 spline and fit with no problems. Only thing I can figure is that it was from a newer trans and that this might be an oil change? See pic below, just wondering if it would be weaker than what came out of there.
