Keeping up with the services like oil changes and transmission fluid & filter changes, for sure. Never letting it overheat and thus be more likely to drop valve seats. Speaking as the owner of an 08 KK with 228,000 miles. Also, just fixing little things when they break, so that it continues to be a fun vehicle to drive. I'm a big fan of low mileage Mopar parts from the junkyard for non-powertrain part replacements.What's the secret to keeping it going so long?
Could one plumb in a filter on the return line from the trans cooler? This is something I do to all my fluid power systems.It’s a normal 42RLE with VLP (variable line pressure), same as on the KJ’s. It just has a cap instead of a dipstick.
The transmission has a filter inside the pan, because it’s a regular old transmission despite the “dealer service only” note on the fill cap. You can do a fluid and filter service on it by dropping the pan.Could one plumb in a filter on the return line from the trans cooler? This is something I do to all my fluid power systems.
