     The inspection plate is shown in this picture. It is not a forward position for the shifter. It is only for making easy inspections of the transmission.
     All of the measurements were made with a tape measure and eyeballed, so they are not accurate. They are only to give everyone a rough idea of the dimensions of this transmission.
     Bottom view of T56.
     Tail housing of the T56 with some commonly requested measurements.
     Front spindle on the T56 with spindle length dimensions.
     Just a couple of helpful views of the T56 from both ends.
     Picture taken from the side and towards the tail of the T56.
     Picture taken from the top and towards the tail of the T56.
     Front side view of the adapter plate that comes with the Retro-Fit T56. We can not get these separately, but we can drill the adapter plate so it will fit a standard bell housing. The blue arrows point to the holes that Chevrolet has drilled in the adapter plate. We do not make this adaptor plate or own the rights to it.
     Back side view of the adapter plate also with blue arrows pointing to the holes drilled by Chevrolet.
     A good view of the adapter plate mounted on the front of the T56 transmission and ready to be bolted to an engine.
     Oil fill location and recommended oil label. Position of this hole can be determined by looking at the orange tag in the bottom view above.
