Valve Body:    C4

Every valve body is disassembled, hand cleaned, and custom modified to fit your application using my own parts – no off the shelf kits.  Depending on the calibration you and your car desire, each valve body includes modifications to increase line pressure, including custom separator plate and valve modifications.  Shift firmness is tailored to your desire/needs, with shift overlap or flare eliminated.  No more band burn!


Each valve body is also boxed with a new Yellow Stripe modulator valve.


A billet aluminum “C” servo can be added to your order for an additional charge (but shipped free of charge).  This is the best servo I have found and is made by Sonnax.  This is a critical upgrade for those experiencing intermediate band failures.  It not only increases holding capacity but improves shift feel as well.  It is a highly suggested upgrade for those with high horsepower and torque in large cars and trucks.


Each valve body can be manually shifted or used in automatic as well.  I only offer full auto /manual valve bodies at this time.

My 9-bolt C4 valve bodies are complete and ready to install.  They come boxed with anew filter and gaskets and simple instructions to guide you.  All that you need is time, a torque wrench, a few tools, and your choice of ATF.
