Before you go spending any coin on coolers, hoses, and fittings, check to make sure you have a problem. If you've modified your Jeep with bigger tires, and take it crawling or get stuck in traffic (lack of airflow) odds are good you are running your transmission past its accepted design parameters. We tapped Auto Meter to help us figure some things out. We picked up a few transmission temp manifolds (PN 2286), some full-sweep gauges, and some extra senders (PN 2252). We mounted the manifolds and senders in various places in the system to monitor the temp real-time.
