I am getting a P0748 code after I changed to a D3 valve body with a T-break, which entailed me to cut the epc sil power wire to convert to the t-brake sil. Is there any way to eliminate the ecm from checking for this?
I have it turned of in the DTC list but it still trips and causes the trans to go to a partial limp mode not letting the lock up to engage in 4th and wont let it down shift at full throttle.
