AWESOME!
Getting the trans to work right I think will take a proper pressure gauge. I'm not an expert on auto transmissions at all, not in any way, but when I was running my 904 I had a similar thing going on. The 1-2 was soft and sometimes I didn't even notice it shifted, but then it would bark into 3rd.
Might be a good idea to start a new thread in the transmission forum and ask for some guidance on fine tuning. I'm sure your local helper member can probably give some good guidance too!
Also, don't stress the mph on the shift, rpm will translate better to your modified stall and camshaft. Optimum shift points will depend on what your power curve looks like and rear end gear - but I don't think you're so far from stock to complete ignore the OEM recommendations.
