My TC in my 1999 Grand (4.7) went out. It made a horrible popping noise since the day I got it. A tech @ a jeep dealership told me it was a normal noise for that year. Needless to say, I was out playing in the mud when it made it's last POP! My father in law has a 249 TC with 20,000 miles. Can I replace my 247 TC out of my WJ with his 249 TC out of a ZJ?
