23,000 miles of hell on a Ingelwood transmission rebuild and it has never been right. First issue was the transfer case pump rub. Then they didn't greese the slip yoke. It was never trouble shot correctly. Still had codes and stuff. Found out it didn't need rebuilt. Chafed wire coming out of the TCM. Then they say replace the transfer case for the intermittent bone crushing hard 1 2 shift . Good for a few days and it back. This is what $4k gets you.
