MECHANISM-BRAKE TRANSMISSION SHIFT INTERLOCK
DESCRIPTION
The Brake Transmission Shifter Interlock (BTSI), is a
solenoid operated system. It consists of a solenoid
permanently mounted on the gearshift cable.
OPERATION
The system locks the shifter into the PARK position. The interlock system is engaged whenever the ignition switch
is in the LOCK or ACCESSORY position. An additional electrically activated feature will prevent shifting out of the
PARK position unless the brake pedal is depressed approximately one-halfan inch. A magnetic holding device in
line with the park lock cable is energized when the ignition is in the RUN position. When the key is in the RUN
position and the brake pedal is depressed, the shifter is unlocked and willmove into any position. The interlock
system also prevents the ignition switch from being turned to the LOCK or ACCESSORY position, unless the shifter
is fully locked into the PARK position.
DIAGNOSIS AND TESTING - BRAKE TRANSMISSION SHIFT INTERLOCK
1. Verify that the key can only be removed in the PARK position.
2. When the shift lever is in PARK And the shift handle pushbutton is in the “OUT” position, the ignition key cylinder
should rotate freely from OFF to LOCK. When the shifter is in any other gear or neutral position, the ignition key
cylinder should not rotate to the LOCK position.
3. Shifting out of PARK should not be possible when the ignition key cylinder is in the OFF position.
4. Shifting out of PARK should not be possible while applying normal pushbutton force and ignition key cylinder is
in the RUN or START positions unless the foot brake pedal is depressed approximately 1/2 inch (12mm).
5. Shifting out of PARK should not be possible when the ignition key cylinderisintheACCESSORYorLOCK
positions.
6. Shifting between any gears, NEUTRAL or into PARK may be done without depressing foot brake pedal with
ignition switch in RUN or START positions.
ADJUSTMENTS - BRAKE TRANSMISSION SHIFT INTERLOCK
Correct cable adjustment is important to proper interlock operation. Thegearshift cable must be correctly adjusted
in order to shift out of PARK.

ADJUSTMENT PROCEDURE
1. Remove the steering column trim as necessary for
access to the brake transmission shift interlock.
2. Shift the transmission into the PARK position.
3. Pull upward on both the BTSI lock tab (4) and the
gearshift cable lock tab (3).
4. Verify that the shift lever is in the PARK position.
5. Verify positive engagement of the transmission
park lock by attempting to rotate the propeller
shaft. The shaft will not rotate when the park lock is
engaged.
6. Turn ignition switch to LOCK position.Be sure
ignition key cylinder is in the LOCK position.
Cable will not adjust correctly in any other
position.
7. Ensure that the cable is free to self-adjust by push-
ing cable rearward and releasing.
8. Push the gearshift cable lock tab (3) down until it snaps in place.
9. Locate the BTSI alignment hole in the bottom of the BTSI mechanism betweentheBTSIlocktabandtheBTSI
connector.
10. Move the BTSI assembly up or down on the gearshift cable until an appropriate size drill bit can be inserted into
the alignment hole and through the assembly.
11. Push the BTSI lock tab (4) down until it snaps into place and remove the drill bit.
12. Install any steering column trim previously removed.
BTSI FUNCTION CHECK
1. Verify removal of ignition key allowed in PARK position only.
2. When the shift lever is in PARK, the ignition key cylinder should rotate freely from off to lock. When the shifter
is in any other position, the ignition key should not rotate from off to lock.
3. Shifting out of PARK should be possible when the ignition key cylinder isin the off position.
4. Shifting out of PARK should not be possible while applying normal force,and ignition key cylinder is in the run
or start positions, unless the foot brake pedal is depressed approximately1/2inch(12mm).
5. Shifting out of PARK should not be possible when the ignition key cylinder is in the accessory or lock position.
6. Shifting between any gear and NEUTRAL, or PARK, may be done without depressing foot brake with ignition
switch in run or start positions.
7. Engine starts must be possible with shifter lever in PARK or NEUTRAL positions only. Engine starts must not be
possible in any position other than PARK or NEUTRAL.
8. With shifter lever in the:
PARK position - Apply upward force on the shift arm and remove pressure. Enginestartsmustbepossible.
PARK position - Apply downward force on the shift arm and remove pressure. Engine starts must be possible.
NEUTRAL position - Normal position. Engine starts must be possible.
NEUTRAL position - Engine running and brakes applied, apply upward force on the shift arm. Transmission
shall not be able to shift from neutral to reverse.

NOTE: One of the oil pan bolts (5) has a sealing
patch applied from the factory. Separate this bolt
for reuse.
2. Loosen pan bolts and tap the pan at one corner to
break it loose allowing fluid to drain, then remove
the oil pan.
3. Install a new filter and o-ring on bottom of the valve
body and tighten retaining screws to 5 Nꞏm (45 in.
lbs.).
NOTE: Before installing the oil pan bolt (5) in the
bolt hole located between the torque converter
clutch on and U/D clutch pressure tap circuits, it
will be necessary to replentish the sealing patch
on the bolt using Mopar
Lock & Seal Adhesive.
4. Clean the oil pan and magnet. Reinstall pan using
new Mopar
Silicone Adhesive sealant. Tighten oil
pan bolts to 20 Nꞏm (14.5 ft. lbs.).
5. Pour four quarts of Mopar
AT F + 4 , A u t o m a t i c
Transmission Fluid, through the dipstick opening.
6. Start engine and allow to idle for at least one minute. Then, with parkingand service brakes applied, move selec-
tor lever momentarily to each position, ending in the park or neutral position.
7. Check the transmission fluid level and add an appropriate amount to bring the transmission fluid level to 3mm
(1/8 in.) below the lowest mark on the dipstick.
8. Recheck the fluid level after the transmission has reached normal operating temperature, 82° C (180°F).
9. To prevent dirt from entering transmission, make certain that dipstickis fully seated into the dipstick opening.
TRANSMISSION FILL
To avoid overfilling transmission after a fluid change or overhaul, perform the following procedure:
1. Remove dipstick and insert clean funnel in transmission fill tube.
2. Add following initial quantity of Mopar
ATF+4totransmission:
a. If only fluid and filter were changed, add3 pints (1-1/2 quarts)of ATF +4 to transmission.
b. If transmission was completely overhauled, torque converter was replaced or drained, and cooler was
flushed, add12 pints (6 quarts)of ATF +4 to transmission.
3. Apply parking brakes.
4. Start and run engine at normal curb idle speed.
5. Apply service brakes, shift transmission through all gear ranges then back to NEUTRAL, set parking brake, and
leave engine running at curb idle speed.
6. Remove funnel, insert dipstick andcheck fluid level. If level is low,add fluid to bring level to MIN mark on
dipstick.Check to see if the oil level is equal on both sides of the dipstick. If one side is noticably higher than
the other, the dipstick has picked up some oil from the dipstick tube. Allowthe oil to drain down the dipstick tube
and re-check.
7. Drive vehicle until transmission fluid is at normal operating temperature.
8. With the engine running at curb idle speed, the gear selector in NEUTRAL,and the parking brake applied, check
the transmission fluid level.
CAUTION: Do not overfill transmission, fluid foaming and shifting problems can result.
9. Add fluid to bring level up to MAX arrow mark.
When fluid level is correct, shut engine off, release park brake, remove funnel, and install dipstick in fill tube.

GEARTRAIN-PLANETARY
DESCRIPTION
The planetary geartrain is located between the input
clutch assembly and the rear of the transmission case.
The planetary geartrain consists of two sun gears, two
planetary carriers, two annulus (ring) gears, and one
output shaft.
OPERATION
The planetary geartrain utilizes two planetary gear setsthat connect thetransmission input shaft to the output shaft.
Input and holding clutches drive or lock different planetary members to change output ratio or direction.

STATOR
The stator assembly is mounted on a stationary shaft
which is an integral part of the oil pump. The stator (1)
islocatedbetweentheimpeller (2) and the turbine (4)
within the torque converter case.
The stator contains an over-running clutch (1-4), which
allows the stator to rotate only in a clockwise direction.
When the stator is locked against the over-running
clutch, the torque multiplication feature of the torque
converter is operational.
