The transmission level should be checked when the oil is changed. Since your hands are apt to be pretty oily at these times, you shouldn't mind this job. To check the level, remove the filler plug in the right side of the transmission case from under the car. There is a similar plug in the overdrive case at the rear of the transmission. With the car level, oil should drip out. If it runs our in a steady stream, let it run until it just drips. Any fluid required can be pumped in with a suction gun. All transmissions use SAE 80W-90 Gear oil, except the 1982 T4 and T5. These use Dexron®II automatic transmission fluid.

Pacer 3-Speed with Overdrive

The overdrive unit shares a common supply of lubricant with the manual transmission. The fluid level is checked at the transmission fill plug in the same manner as for manual transmissions without overdrive. The fluid level should be checked every 5,000 miles.

If lubricant is required, use only API GL-4 SAE 80W-140 gear lubricant.


CAUTION
Don't use antifriction or limited slip differential lubricant in the transmission/overdrive unit.

FLUID CHANGE



The manufacturer says that the transmission lubricant need never be changed, except for overhaul. However, if you bought your car used, or if you subject it to heavy duty use, you may want to change the lubricant. To do this, first drive the car until it is warm, then:

  1. Wipe off the area around the drain and filler plugs for the transmission and overdrive. Remove both plugs and drain the oil into a container.
  2.  
  3. Replace the drain plug after cleaning off the threads.
  4.  
  5. Use a suction gun to fill the transmission or overdrive through the filler hole. The correct level is even with the bottom of the filler hoe. See `Fluid level Checks,' earlier in this information, for the proper lubricants.
  6.
