MANUAL TRANSMISSION-T56 - SERVICE INFORMATION
DIAGNOSIS AND TESTING
MANUAL TRANSMISSION - T56
LOW LUBRICANT LEVEL
A low transmission lubricant level is generally the result of a leak, inadequate lubricant fill or incorrect lubricant level
check.
Rear transmission leakswill be from the oil seals or component mating surfaces.
Front transmission leakswill be from the front bearing retainer or retainer seal. Lubricant may dripfromtheclutch
housing after extended operation. If leak is severe, it may contaminate the clutch disc.
Lubricant level checkcan only be made when the vehicle is level and allowing the lubricant to settle for a minute
before checking. This will ensure an accurate check and avoid an underfillor overfill condition.
HARD SHIFTING
Hard shifting is usually caused by low lubricant level, improper or contaminated lubricants. This will cause noise,
excessive wear, internal bind, and hard shifting. Substantial lubricantleaks can result in gear, shift rail, synchro, and
bearing damage. The first indications of component damage is usually hardshifting and noise.
Shift component damage, clutch adjustment, worn pressure plate or disc are also causes of increased shift effort. If
clutch problem is advanced, gear clash during shifts can result. Worn or damaged synchro rings can cause gear
clash when shifting into any forward gear. In some new or rebuilt transmissions, new synchro rings may tend to stick
slightly causing hard or noisy shifts. In most cases, this condition will decline as the rings wear-in.
TRANSMISSION NOISE
Most manual transmissions make some noise during normal operation. Rotating gears generate a mild whine that is
audible, but generally only at extreme speeds.
Severe, highly audible transmission noise is generally the initial indicator of a lubricant problem. Insufficient,
improper or contaminated lubricant will promote rapid wear of gears, synchros, shift rails, forks and bearings. The
overheating caused by a lubricant problem, can also lead to gear and bearing damage.
STANDARD PROCEDURE - DRAIN AND FILL
1. Raise and support vehicle.
2. Remove drain plug (1) on transmission tail housing
and drain fluid.
3. Install drain plug and tighten to 38 Nꞏm (28 ft. lbs.).
4. Remove transmission fill plug on left side of the
transmission case.
5. Fill transmission to bottom of the fill hole.
6. Install transmission fill plug and tighten to 27 Nꞏm
(20 ft. lbs.).

SEAL-EXTENSION HOUSING
REMOVAL
NOTE: If extension housing slip yoke bushing is
worn the housing must be replaced,
1. Remove propeller shaft.
2. Remove seal with a seal pick (1).
3. Clean and inspect extension housing where the
seal was located.
INSTALLATION
1. Install seal into extension housing (3) with Installer
9372 (1) and Handle C-4171(2).
2. Install propeller shaft.
3. Check transmission fluid level.

10. Remove input shaft bearing (1) with Splitter P-334
(2) and a press.
INSTALLATION
1. Install new seal from the fluid side with Installer
9366.
2. Install input shaft bearing (2) on shaft with Installer
6052 and Installer MB-991317 (2).
3. Install new bearing cup in front adapter with origi-
nal shim behind cup.
4. Clean sealing surfaces of the transmission case
and adapter plate.
5. Install new input shaft and adapter plate (without
any Mopar Gasket Maker).
6. Check output shaft end play. It should be the same
as measured during the disassemble procedure. If
end play is greater than original reading, install a
thicker shim. If end play is less than original read-
ing, install a thinner shim.
7. After the correct shim has been installed, remove
the adapter plate and apply Mopar Gasket Maker
to the sealing surfaces.
8. Install adapter and tighten adapter bolts to 34 Nꞏm (25 ft. lbs.).
9. Install transmission.

When Monitored:
Continuously with the ignition on and engine running.
Set Condition:
DTC will set when the transmission temperature does not reach a normal operating temperature within a given
time frame. Time is variable due to ambient temperature. Approximate DTC set time is 10 to 35 minutes. The
following are starting temperature to warm up times to set this DTC: starting temperature -40° C (-40° F) warm
up time 35 minutes, starting temperature -28° C ( -20° F) 25 minutes, starting temperature -6.6° C (20° F) 20
minutes, starting temperature 15.5 ° C (60° F) 10 minutes. When the fault isset, calculated temperature is
substituted for measured temperature, however the DTC is stored only after three consecutive occurrences.

Theory of Operation
The temperature sensor is used to sense the temperature of the transmission fluid. Transmission fluid temperature
can affect shift quality, torque converter operation and when or if some diagnostics are run. A failed temperature
sensor could affect the OBD diagnostics. If a problem occurs in the transmission temperature sensor circuit, trans-
mission temperature will be based on a calculated value.

Theory of Operation
Line pressure is measured by the Line Pressure Sensor (LPS) and regulationis achieved by changing the duty
cycle of the Pressure Control Solenoid (PCS) controlled by the Transmission Control System. (5% duty cycle =
solenoid off = Max line pressure, 62%duty cycle = solenoid on = Min line pressure). The Transmission Control
System calculates the desired line pressure based on inputs from both the engine and transmission.
The Transmission Control System calculates torque input to the transmission and uses it as the primary input to the
desired line pressure calculation. This is called Torque Based Line Pressure. In addition, the line pressure is set to
a preset level 827 or 931 kPa (120 or 135 psi) during shifts and in Park and Neutral to ensure consistent shift
quality. The desired line pressure is continuously being compared to the actual line pressure. If the actual line pres-
sure is consistently lower than the target while driving, the line pressure low DTC P0868 will set.
