Maintenance Schedule Beyond 150k

Camaron32 · Jul 18, 2018

I recently purchased a 2009 Ram SLT 5.7L with 181k on the odometer. Now before I go all OCD about this and overthink it, has anyone found a maintenance schedule that goes beyond 150k? Or does a maintenance schedule just loop back around to the very first oil change? Any input would be most appreciated.

First thing I would do is change all fluids including difs oil, transfer case if you have, trannie fluid, coolent. Also pull a spark plugs and see how looks and inspect/ change the air filter. After that I would start with the first service listed in the manual.

^ What he said.
Also, go around and check all the grounds n make sure they are clean then put some corrosion inhibitor on them, there’s a lot of them that you can’t see so I recommend downloading the service manual for your truck to find them. A bad ground can cause all kinds of funky electrical issues.

Call me scared but if the tranny fluid looks clean and if you have no record of service I'd leave that one alone. In my younger years when driving high mileage cars I killed more than one tranny by thinking I was doing something good by changing the fluid. It falls into the, "if it isn't broken, don't fix it" category.

That usually only applies when you have it flushed with a machine at a shop, just dropping the pan and new filters doesn’t harm anything. It’s when a machine is used that causes problems because the pressure from flushing knocks buildup loose and clogs up the valve body’s etc.

I would keep it simple. New trans fluid and trans filter (must use pan gasket, not a sealer) As said, some of the new "trans service offers" can cause more issues than they are supposed to prevent. Oil and filter and enjoy the drive.

That is damn good advice.

This is what I've heard and I generally agree.... BUT, I drained/filled the tranny on my 99 F150 thinking I was doing the right thing and 2 days later it started slipping and clunking (I know it's a Ford so that could happen anytime

). The truck had 110K miles of which I had put 70K and never had even a hint of a problem. I checked the fluid level and everything was fine. The behavior continued and was getting worse so I traded it in.

Old trannys are just super fragile.... OP, be careful.

I would check the brakes as well. have all the zergs every where greased. If there is an external fuel filter, change it too.

Win some loose some. At 181k who knows how it’s been maintained. I wish the manufacturers still put inspection plates on vehicles.
