The trans would have to be removed in order to gain access to the boost valve. You will need to remove the oil pump and disconnect the ISS to access the boost valve. You will also have to drop the pan and remove the TC lockup solenoid prior to removing the pump. I would also add the Sonnax 77805E-K TCC apply valve, transgo unbreakable pump rings and high rev pump slide spring 700-PKH along with a new pump bushing, torque converter seal and the obvious gaskets and seals. Also inspect the pump rotor and vanes. All can be had for roughly $40.00

 

Thanks 07, I appreciate the info.
I have the Fitzall A74741CB TCC valve already and the Sonnax boost valve.
What would you expect a trans shop to charge to do all of that?
I was looking forward to tearing into my trans for the first time, hah.
