I need help, my camaro is 75, The 6 cylinder model came with Saginaw 3 speed transmission .. I want to put a new transmission the 4 speed my 6 cylinder engine .. but not if it fits the m20, m21 and m22 the t10
which would be recommended to put in my 6l
thanks

 

Not sure if I follow you? If you're asking which of these transmissions is a direct bolt in, then the answer is the M20, M21, and T10. The M22 is a fine spline input shaft, and also a larger TH400 style output, as is the Super T10, so both would take a little work to make them fit.

 

Yes .thanks for your answer
