Pinpoint Test F: Hard Shifting

Normal Operation

The manual transaxle is controlled by a floor-mounted gearshift lever located in the floor console. Connection between the floor-mounted gearshift lever and the manual transaxle gearshift control assembly is made through 2 gearshift cables.

When the operator moves the floor-mounted gearshift lever, that movement is transmitted through 2 gearshift cables routed through the body to the transaxle. The 2 gearshift cables are attached to the transaxle at the gearshift control assembly. The gearshift control assembly transfers the movement of the gearshift cables to the shift rods and shift forks located inside the transaxle.

The clutch is designed to transfer the power from the engine to the transmission, which may be either stationary (starting) or rotating at a different speed (upshifting or downshifting). The clutch is functioning correctly when both the engine and transmission are rotating at the same speed with the clutch engaged. Clutch pedal movement is transmitted by fluid pressure, which actuates the clutch release hub and bearing. The clutch release hub and bearing pushes on the spring center towards the flywheel. The diaphragm spring pivots at the fulcrum, relieving the load on the clutch pressure plate. Steel spring straps riveted in the clutch pressure plate cover pull the clutch pressure plate from the clutch disc, disengaging the engine torque from the transmission.

This pinpoint test is intended to diagnose the following:
- Transmission fluid level
- Clutch hydraulic fluid level
- Clutch pressure plate
- Shift linkage



PINPOINT TEST F: HARD SHIFTING

-------------------------------------------------
F1 CHECK THE FLUID LEVEL


- Ignition OFF.
- Inspect the fluid level in the brake master cylinder reservoir.
- Is the fluid level within the MAX and MIN level marks?

Yes
GO to F2.

No
ADD brake fluid and CHECK for leaks in the clutch and brake systems.

-------------------------------------------------
F2 CHECK THE CLUTCH PEDAL FREE PLAY


- Press the clutch pedal lightly by hand.
- Measure the distance the clutch pedal travels.
- Is the clutch pedal travel within 5-13 mm (0.20-0.51 in)?

Yes
REFER to Manual Transmission/Transaxle or shifter concerns. Manual Transmission/Transaxle

No
CHECK the clutch pressure plate for damage. REFER to Clutch Pressure Plate Check Procedures.
