I had a little trouble with the fittings for the transmission lines. I am replacing the quick connect fittings with AN-6 adapters. I ordered the ones from Summit Racing that are used on 700R4 and various others, but the transmission threads were a little bigger diameter on my 4L65E.

I called Summit, and they checked the part # and thought it should fit. They didn't show anything else that was listed for a 4L65E.

I called Pace performance, and they knew immediately which fitting I needed. The 700R4 has a 1/4 STRAIGHT pipe thread, while the newer 4L65E uses a 9/16-18 straight thread. Pace gave me the part number.

I called Summit and explained all of this, and they were AWESOME!!!!
They sent me the two correct fittings FREE, and no shipping charges either!

So, tomorrow I'll finish those two lines also.
