I recently brought my jeep to dealership for oil change and was given a list of rec services: emission, ft/rear diff, coolant/trans flush. Suggestions? Can't do all!

Question type: Maintenance & Repair

I have 09 Wrangler, not lifted.  The engine is a 3.8L and its a V6 SMPI Engine.

Forget the transmission flush for sure. Forever. And if you are having no problems with overheating, cabin heat works, coolant looks good, that can wait

5,435

it depends on the mileage and how you use your vehicle...the coolant is 5 years or 100,000 miles so your do for that time wise and out of all this breaks down faster then the rest....//the trany if your not having issues( slippage or leaks) I would not touch it...// the diffs would be the same if you have no leaks and the levels are good then let them be

1. Transmission service (most often ignored or overlooked- it’s not broke so don’t fix it mindset) 2. Cooling system service ( overheating and froze up engines do not work. Period.) 3. Emissions- maybe should be #1 since excessively worn piston rings and valve stems/guides are major items needing a leakdown or compression test! 4. Fluid changeout in the diffs and transfer case. Not hard but use the correct fluids and gasket sealants on the covers.
