Internal transmission harness for the 097 & 01N 4 speed automatic transmission. This harness is also know as a printed circuit foil. This harness is prone to failure around 100k miles and can give you a solenoid fault code if broke. As a professional tech I recommend replacing all of the solenoids, harness, filter, gasket and new fluid. Like this harness the solenoids are made to last 100k miles as well. You can find the complete kit on our site. Do it once and be done for another 100K miles.
