Transmission shop in northern Delaware that build a custom Allison's

[stickfolk]

I was wondering if anybody knows of a good transmission shop in northern Delaware that good with Allison transmissions. I am possibly looking to have a custom transmission built to handle the extra HP & Torque
I have a 2002 HD 2500 with a 6.6 Duramax, with about198.876 miles on it.
I installed a 4" turbo back exhaust and a K&N cold air intake.
I have added a PPE standard and I am starting experience some slippage when applying power, this is not long after (resetting) relearning the the transmission a wile after installing the programmer. I don't know if this had any thing to do with this problem.
