My mechanic friends diagnostic reader showed codes P1768 and P1773. With those codes, the engine light on, and the D4 light flashing, along with failing torque converter lock up and intermittent gear shifts we narrowed it down to a bad TCU.

My question is: While trying to find a replacement TCU I have encountered 2 different TCU stock #'s for my model/make/year of car. Both #'s 28100-P8A-003 and 28100-P8A-013 are shown for my car (as shown here: http://parts.sonsacura.com/products/...0-P8A-013.html ) My TCU is marked with the second stock #. What's the difference between the 2 TCU's? Can I sub one for the other? I ask because the 28100-P8A-003 is more readily available than 28100-P8A-013. Someone... anyone.... help!!!
