Diagnostic Aids
Hard shifting in reverse can be diagnosed easily. You should perform a static shift and dynamic shift test. Many other simple factors could occur such as insufficient fluid, excessive fluid or even the wrong transmission lubricant. A misaligned transmission can also cause hard shifting as well as a worn or defective clutch, binding of the shift control. Many internal components can also play a factor in hard shifting such as the front bearing retainer loose or cracked, synchronizer worn, damaged or improperly assembled. A failure to fully depress the clutch pedal when shifting will cause hard shifting in reverse.
Test Description
The number(s) below refer to the step number(s) on the diagnostic table.
-
This step checks for air in the hydraulic lines, this will also cause the transmission to hard shift in reverse.
-
This step checks for a faulty shift tower.
-
This step checks for a faulty or worn clutch pressure plate or clutch driven plate.

DEFINITION: The transmission does not shift smoothly into reverse gear. | |||||||||
1 | Did you review the manual transmission symptom operations and perform the necessary inspections? | Go to Step 2 | |||||||
2 | Test the clutch pedal travel. Refer to Hydraulic Clutch Description . Did you find or repair the condition? | Go to Step 13 | Go to Step 3 | ||||||
Test for air in the clutch hydraulic system. Is there air in the hydraulic system? | Go to Step 4 | Go to Step 5 | |||||||
4 | Pump the clutch pedal 25 times. Does the transmission still shift hard? | Go to Step 5 | System OK | ||||||
Inspect the transmission shift tower for binding. Did you find and repair the condition? | Go to Step 13 | Go to Step 7 | |||||||
6 | Replace the transmission shift tower. Refer to Shift Tower Replacement . Did you find and repair the condition? | Go to Step 13 | Go to Step 7 | ||||||

8 | Drain and refill the transmission with the correct type fluid. Refer to Lubrication Specifications . Did you find and repair the condition? | Go to Step 13 | Go to Step 9 | ||||||
Remove the transmission. Refer to Transmission Replacement . Inspect the clutch pressure pate and/or clutch driven plate. Is the clutch pressure plate and/or clutch driven plate worn or faulty? | Go to Step 10 | Go to Step 11 | |||||||
10 | Replace the clutch pressure plate and/or clutch driven plate. Refer to Clutch Assembly Replacement in Clutch. Did you find and repair the condition? | System OK | Go to Step 11 | ||||||
11 | Disassemble the transmission. Refer to Transmission Disassemble in all the Transmission sections. Inspect the transmission for an internal binding, possibly caused by one of the following:
Is there internal binding? | Go to Step 12 | -- | ||||||
