Looking for some help here the truck listed above is a k1500. I recently was replacing the pitman arm (along with the idler arm/bracket, outer/inner tie rods on both tires). When I was replacing the pitman, I may or may not have caused a small leak from the gearbox (it had 290,000 miles so I was fine replacing it).
Now I have replaced the Gearbox too and I am getting error code P0748. I am concerned I did something wrong in the assembly and now its affecting the transmission.
Can anyone provide any direction? My head is in the clouds.
have the same problem?
