Call Rob at needswings, he can send you everything you need with OEM parts and fluids. check the fluid level, use the manual method (measure temp of pan and get the OEM trans dip stick), the zip tie measuring method was not accurate for me (I think it hit the valve body before hitting the bottom of the pan). If your fluid level is low then you need to replace the connector plug housing as it's O rings go bad (very cheap fix). You can jack up the passenger side of the car, remove the connector plug cable (twist lock design) then 7mm 1/4" drive deep socket to remove the retaining bolt. When you replace it DO NOT over tighten this bolt, its very low torque. You may have to find a high powered OBDII scanner to clear the code, I had success with a snap on Solus ultra with the European car software installed on the sd card.
