Others can get more detail.

But the trans was not designed for high. Horse power.

The 56 carribean used a different pump in torque converter.

And different valve body.

For higher horse power.

Best to contact Ross Miller. Get his input.

PM him.

The shift points are different on 55. The 56 has L R H D P.N.

THE 55 has those triangles between gear shift. On steering .
