so my rango 5.9 is throwing p0420 and p1740 codes. after reading into the 1740 im not happy that i might have to replace the tranny but it shifts perfectly smooth and fine. better than my current 3.9l dak with 117k on the damn thing. idk how long they've been on i just got it and they were on when i got it. but if its not showing any signs of wear and tear on the tranny is it really that serious? another question with the 2000 durango 5.9l slt 4x4 with a 46RE are those tranny's cooled or no? i know my dak is but i haven't gotten a chance to look at the durango yet.

try replacing or even unplugging the 02 sensors, they are on the same circuit as trans sensors
