FLUID RECOMMENDATIONS



All vehicles use a multipurpose gear oil. The recommended types are: API GL-3, GL-4 or GL-5 with the viscosity SAE 75W-90 or 80W-90.

LEVEL CHECK



See Figures 1, 2, 3 and 4

The oil in the manual transmission should be checked at least every 7500 miles (12,000 km) and replaced every 25,000-30,000 miles (40,000-48,000 km). Even more frequently if driven in deep water.

  1. With the truck parked on a level surface, remove the filler plug (17mm) from the side of the transmission housing. A gasket will also have to be removed and discarded.
  2.

  1. If the lubricant begins to trickle out of the hole, there is enough. Otherwise, carefully insert your finger (watch out for sharp threads) and check to see if the oil is up to the edge of the hole.
  2.  
  3. If not, add oil through the hole until the level is at the edge of the hole. Most gear lubricants come in a plastic squeeze bottle with a nozzle; making additions simple. You can also use a common everyday kitchen faster.

DRAIN AND REFILL



See Figures 5, 6 and 7

The oil in the manual transmission should be changed at least every 30,000 miles (48,000 km).

  1. The transmission oil should be hot before it is drained. If the engine is at normal operating temperature, the transmission oil should be hot enough.
  2.  
  3. Raise the truck and support it properly on jackstands so that you can safely work underneath. You will probably not have enough room to work if the truck is not raised.
  4.  
  5. The drain plug is located on the bottom of the transmission. It is usually on the passenger side on four speeds, and on the bottom center of five speeds. Place a pan under the drain plug, then remove it. Keep a slight upward pressure on the plug while unscrewing it, this will keep the oil from pouring out until the plug is removed.

CAUTION
The oil will be HOT. Be careful when you remove the plug so that you don't take a bath in hot gear oil.

  1. Allow the oil to drain completely.
  2.  
  3. Clean off the plug then install it, tightening it until just snug.
  4.  
  5. Remove the filler plug from the side of the transmission case. It is usually on the driver's side of four speeds, and on the passenger side on five speeds. There will be a gasket underneath this plug. Replace it every time the bolt is removed.
  6.  
  7. Fill the transmission with gear oil through the filler plug hole.
  8.  
  9. The oil level should come right up to the edge of the hole. You can stick your finger in to verify this. Watch out for sharp threads.
  10.  
  11. Install the filler plug and gasket, lower the truck, then check for leaks. Dispose of the old oil in the proper manner.
