Even though Fiat/Chrysler threw that wonderful W5A580 transmission in the Wrangler, you still need to keep your eye on the transmission and service them appropriately. With automatic and manual transmissions you have two very different systems.
Though, if your transmission gives up on you, you can kiss your off-roading days over right away. We’re going to talk about some key areas to keep an eye on with both types of transmissions and some symptoms that will tell you right away whether or not you need to tear into things.
Automatic: Automatic Transmissions operate on hydraulics, and that means you will have no room for leaky seals whatsoever. Every so often, it’s a great idea to check your seals and gaskets on the shafts and pans of the transmission.
With a manual trans, you may experience a slip in the shifting of gears. When this happens, take a look at the fluid level. If it’s low, that tells you a lot right there. There is likely a leak somewhere and you will have to repair the leak before the problem worsens. Though, if the transmission is leaking and there are no leaks present, it’s time to consider taking the transmission to a shop for a proper repair.
Manual: Manual transmissions may have less working parts than automatics but that doesn’t make them bulletproof. For routine maintenance, you should change the gear oil within appropriately. This will keep the moving parts clean and prolong their lifespan.
If the clutch is starting to wear out, change it. A fresh clutch is easier on the internals and will keep you from destroying or wearing out the gears. If there is a grinding coming from the gearbox as you drive along, you can rest assured that it’s time to seek a total tear down or replacement.
