light DODGE RAM SRT-10 2006 Service Repair Manual

STANDARD PROCEDURE
INITIAL OPERATION
WARNING: The fluid level should be checked with engine off to prevent injury from moving components.
NOTE: Remove as much of the old fluid out of the system as possible with a suction tool or by removing
a hose, when a component has failed. Then refill it with fresh fluid until itis clean. This may have to be
done more than once.
CAUTION: MOPAR
ATF+4 is to be used in the power steering system. No other power steering or auto-
matic transmission fluid is to be used in the system. Damage may result to the power steering pump and
system if any other fluid is used, and do not overfill.
Wipe filler cap clean, then check the fluid level. The dipstick should indicateCOLDwhen the fluid is at normal
ambient temperature.
1. Fill the pump fluid reservoir to the proper level and let the fluid settlefor at least two minutes.
2. Start the engine and let run for a few seconds then turn engine off.
3. Add fluid if necessary. Repeat the above procedure until the fluid levelremains constant after running the engine.
4. Raise the front wheels off the ground.
5. Slowly turn the steering wheel right and left, lightly contacting the wheel stops at least 20 times.
6. Check the fluid level add if necessary.
7. Lower the vehicle, start the engine, and use the DRB III to activate the hydraulic fan on full fan operation.
8. Turn the steering wheel slowly from lock to lock.
9. Stop the engine, check the fluid level and refill as required and repeat the process
CAUTION: Do not run a vehicle with foamy fluid for an extended period. This may cause pump damage.
10. If the fluid is extremely foamy or milky looking, allow the vehicle to stand a few minutes and repeat the pro-
cedure.
11. While the vehicle is in park, use the DRB III to activate the hydraulic fan to full fan operation and briefly rev the
engine up to 3000 rpm to fully engage the hydraulic fan.
12. Check the fluid level add if necessary.

DIAGNOSIS AND TESTING
MANUAL TRANSMISSION - G56
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 input shaft retainer seal. Lubricant may drip from theclutchhousing
after extended operation. If leak is severe, it may contaminate the clutchdisc.
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 under or 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 synchronizer 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, synchronizer rings, shift rails, forks and bear-
ings. The overheating caused by a lubricant problem, can also lead to gear and bearing damage.

12. Remove shift fork tie strap.
13. Apply Mopar™ Gasket Maker to the shift tower
opening.
14. Install shift tower (2) and tighten bolts (1) to 23
Nꞏm (17 ft. lbs.).
15. Install back up lamp switch (1) and bolt (2).
INSTALLATION
1. Clean transmission front housing mounting surface.
2. Apply light coat of Mopar high temperature bearing
grease or equivalent to contact surfaces of follow-
ing components:
release fork (1) ball stud (2)
release bearing slide surface (3)
input shaft splines (4)
release bearing bore (5)
propeller shaft slip yoke.

LOW LUBRICANT LEVEL
A low transmission lubricant level is generally the result of a leak, inadequate lubricant fill or incorrect lubricant level

4.CHECK THE (Z908) AND (Z977) GROUND CIRCUITS FOR AN OPEN
Turn the ignition off to the lock position.
Disconnect the PCM C4 harness connector.
NOTE: Check connectors - Clean/repair as necessary.
CAUTION: Do not probe the PCM harness connectors. Probing the
PCM harness connectors will damage the PCM terminals resulting
in poor terminal to pin connection. Install Miller tool #8815 to per-
form diagnosis.
Using a 12-volt test light connected to 12-volts, check the (Z908) and
(Z977) Ground circuits in the appropriate terminals of Miller tool #8815.
NOTE: The test light must illuminate brightly. Compare the bright-
ness to that of a direct connection to the battery.
Does the test light illuminate brightly for all the Ground cir-
cuits?

Turn the ignition off to the lock position.
Disconnect the Transmission Solenoid/pressure Switch Assembly har-
ness connector.
Disconnect the Line Pressure Sensor/Variable Force Solenoid Assembly
harness connector (if equipped).
Ignition on, engine not running.
With the scan tool under TIPM, actuate the Transmission.
Using a 12-volt test light connected to ground, check all (T16) Trans-
mission Control Output circuits.
NOTE: The (T16) Transmission Control Output circuit branches off
to both Transmission Solenoid/Pressure Switch Assembly, PCM
and (if equipped) the Line Pressure Sensor/Variable Force Solenoid
Assembly.
Does the test light illuminate brightly while cycling on and off
on all (T16) Transmission Control Output circuits?
