Town Car V8-281 4.6L SOHC (1991)
1.
Attach TV Pressure Gauge Set (0-60 psi) T86L- 70002-Al or equivalent, to the TV port on the transmission.
NOTE: If service tool is not available, in order to avoid the exhaust system, obtain the following material and assemble as shown:
- One 1/8-inch NPT female Hansen fitting
- One 1/8-inch NPT male Hansen fitting
- One 1/4-inch NPT 90 degree elbow connector
- One high-pressure hose fitting
The pressure gauge should have 2.4m (8 feet) of flexible hose to make the gauge accessible while operating the engine.
2.
Remove the air cleaner cover and inlet tube from the throttle body inlet for easier access to throttle lever.
3.
Insert tapered end of the tool between the crimped slug on the end of cable and plastic notched rod, also on end of cable assembly. Push in Cable
TV Gauge Tool T86L-70332-A, or equivalent forcing the crimped slug away from the plastic rod. Ensure gauge block is pushed in as far as it will
go.
WARNING: THIS PROCEDURE REQUIRES WORKING IN CLOSE PROXIMITY TO THE EGR SPACER ASSEMBLY WHICH MAY BE
HOT.
4.
Operate engine until normal operating temperature is reached. The transmission fluid temperature should be approximately 38-72°C (100-1 50°F).
Do not make pressure check if transmission fluid is cold or too hot to touch.
5.
Set parking brake and place shift selector in NEUTRAL. With gauge tool in place and engine idling in NEUTRAL, the TV pressure should be
between 207 and 276 kPa (30 and 40 psi).
NOTE: Do not check or set TV pressure in PARK.
6.
If TV pressure meets specification in Step 5, remove gauge tool allowing cable to return to its normal idle position. With engine still idling in
NEUTRAL, TV pressure must be at or near zero (less than 34 kPa (5 psi)).
7.
If TV pressure does not meet specification in either or both Steps 5 and 6, remove gauge tool. Check for and replace damaged components. Adjust
cable as outlined under TV Cable Adjustment-Self-Locking System.
8.
heck TV pressure again. Refer to Steps 3 through 6.
9.
If TV pressure still does not meet specification, it will be necessary to modify adjustment as follows.
10.
Remove gauge tool and pry grooved pin out of grommet on throttle lever.
