SYSTEM-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

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.

CLEANING
Clean the geartrain and case components with solvent. Dry all parts exceptthebearingswithcompressedair.Allow
bearings to air dry.
Do not use shop towels for wiping parts dry unless the towels are made from a lint-free material. A sufficient quan-
tity of lint (from shop towels, cloths, rags, etc.) could plug the transmission filter and fluid passages.
Discard the old case gasket and seals.Do not attempt to salvage these parts. They are not reusable. Replace any
of the overdrive unit snap-rings if distorted or damaged.
Minor nicks or scratches on components can be smoothed with crocus cloth. However, do not attempt to reduce
severescoringonanycomponentswithabrasive materials. Replace severely scored components; do not try to
salvage them.
INSPECTION
Check condition of the park lock components and the overdrive case.
Check the bushings in the overdrive case. Replace the bushings if severelyscored or worn. Also replace the case
seal if loose, distorted, or damaged.
Examine the overdrive and direct clutch discs and plates. Replace the discs if the facing is worn, severely scored,
or burned and flaking off. Replace the clutch plates if worn, heavily scored, or cracked. Check the lugs on the clutch
plates for wear. The plates should slide freely in the drum. Replace the plates or drum if binding occurs.
Check condition of the annulus gear, direct clutch hub, clutch drum and clutch spring. Replace the gear, hub and
drum if worn or damaged. Replace the spring if collapsed, distorted, or cracked.
Be sure the splines and lugs on the gear, drum and hub are in good condition. The clutch plates and discs should
slide freely in these components.
Inspect the thrust bearings and spring plate. Replace the plate if worn or scored. Replace the bearings if rough,
noisy, brinnelled, or worn.
Inspect the planetary gear assembly and the sun gear and bushings. If either the sun gear or the bushings are
damaged, replace the gear and bushings as an assembly. The gear and bushings are not serviced separately.
The planetary carrier and pinions must be in good condition. Also be sure the pinion pins are secure and in good
condition. Replace the carrier if worn or damaged.
Inspect the overrunning clutch and race. The race surface should be smoothand free of scores. Replace the over-
running clutch assembly or the race if either assembly is worn or damaged inany way.
Replace the shaft pilot bushing and inner bushing if damaged. Replace either shaft bearing if rough or noisy.
Replace the bearing snap-rings if distorted or cracked.
Check the machined surfaces on the output shaft. These surfaces should clean and smooth. Very minor nicks or
scratches can be smoothed with crocus cloth. Replace the shaft if worn, scored or damaged in any way.
Inspect the output shaft bushings. The small bushing is the intermediate shaft pilot bushing. The large bushing is the
overrunning clutch hub bushing. Replace either bushing if scored, pitted, cracked, or worn.

6. Install rear bearing (1) and snap-ring (2) on output
shaft. Be sure locating ring groove in bearing is
toward rear.
7. Install overrunning clutch (2) on hub (1). Note that
clutch only fits one way. Shoulder on clutch should
seat in small recess at edge of hub.
8. Install thrust bearing on overrunning clutch hub.
Use generous amount of petroleum jelly to hold
bearing in place for installation. Bearing fits one
way only. Be sure bearing is seated squarely
against hub. Reinstall bearing if it does not seat
squarely.
9. Install overrunning clutch (2) in output shaft (6).
Insert snap-ring pliers inhub splines. Expand pliers
to grip hub. Then install assembly with counter-
clockwise, twisting motion.
