Hey guys looking for some advice. Did the ****** cooler lines and new oil pan on my 05 KJ 3.7 (42RLE), everything seemed to go smooth. Pulled out on the highway and it shifted hard into 2nd and stayed there. Check engine light came on and threw 2 codes. P0731, first gear incorrect ratio and P0700 ****** request MIL.
We can only assume when changing the lines some debris may have been stirred up and clogged something up. Pulled the pan and drained the fluid and refilled. went for a good long drive in the woods in low range hoping it might warm up and clear itself up. No go.
What should we try next? I'm thinking a new valve body in the ******. Seems to be a common problem from my searching.
thx for any suggestions
