#1

Transmission had to be replaced on our 2011 Jeep Wrangler at 100000 miles. Now it is slow in automatic shifting, mechanic says wait 500 miles for transmission to “set in”. Is this true? We paid $4000 for new transmission.

If the computer doesn’t adapt the shift points to your driving style after a week there may be a problem.
