just purchased a 92 escort wagon, runs great minus one thing, have to pump the clutch twice to shift gears. was told to check the gear oil and see if it needs any, thats a good one, dont really know where it is that i need to check. i see two spots on the unit on the bottom but if take the slotted screw out the oil will spill everywhere and the same with the hex nut. so where do i fill the gear oil at? totally baffeled and dont want a mechanic to look at it, he'll tell me to cash for clunker it, gets to good gas milage to do that.
