Servicing - A/t Chevrolet Camaro III рестайлинг

SERVICE INTERVALS

Check fluid level at every oil change. Transmission fluid should be changed and filter replaced every 100,000 miles under normal operating conditions.

Under continuous extreme operating conditions (trailer towing, heavy city traffic with ambient temperature over 90°F/32°C or delivery service), fluid and filter should be changed every 15,000 miles.

CHECKING FLUID LEVEL

1. Warm transmission to normal operating temperature by at lease 15 miles of highway driving. With engine at curb idle. move selector lever through all ranges, ending in Park.
2. Remove dipstick. Wipe dipstick clean and reinstall. Remove again and inspect level. Fluid level should check between "ADD 1 PT. OR .5L" to "FULL HOT" mark on dipstick.

RECOMMENDED FLUID

Use only Dexron II ATF.

FLUID CAPACITY

Note. Quantities listed are approximate. Correct fluid level should be determined by mark on dipstick rather than by amount added.

TRANSMISSION REFILL CAPACITIES

DRAINING & REFILLING

1. With vehicle raised and drain pan placed under transmission, remove front and side transmission oil pan bolts. Loosen rear pan bolts about 4 turns each.
2. Carefully pry pan loose with screwdriver, allow fluid to drain. Remove remaining bolts and oil pan with gasket. Remove filter screen with "O" ring or seal. Clean pan and magnet.
3. Thoroughly clean pan and screen with solvent and dry with compressed air. Paper type filters should be replaced. Install new "O" ring or seal, lubricated with clean oil, onto filter screen.
4. Install filter screen assembly to transmission. Use new pan gasket and install pan. Add proper amount of fluid to transmission through filler tube.
5. Start engine with shift selector lever in Park position and with parking brake set. Check fluid level and add as required. DO NOT overfill.

Scheme 57

1. Rotate T.V. cable adjuster body 90 degrees at transaxle. Pull conduit cable conduit out until slider mechanism hits stop. (Scheme 57)
2. Rotate adjuster body back to original position. Using torque wrench, rotate T.V. cable adjuster until 85 INCH lbs. (N.m) is reached. (Scheme 57): 2.3L ("Quad 4") T.V. Cable

Scheme 58

1. Check that T.V. cable is in full, nonadjusted position. Ensure T.V. cable operates smoothly and connected at transaxle.

2. Ensure shift cable is adjusted correctly and transaxle shift lever is in Neutral. Loosen switch attaching screws. Rotate switch on shifter assembly to align adjustment hole with carrier tang hole.
3. Insert a 3/32" (2.4 mm) wire gauge about 5/8" in switch holes. Tighten attaching screws. Remove wire gauge. New switches may have plastic pin installed in hole. Plastic pin is designed to shear off during operation of shift lever. (Scheme 69): FWD Neutral Safety Switches

TORQUE CONVERTER CLUTCH BRAKE SWITCH

The torque converter clutch brake switch must be adjusted to prevent vehicle stalling at idle. Ensure brake pedal is fully released. Adjust plunger to just touch brake pedal lever.

Cadillac

The THM 440-T4 is equipped with a thermistor switch that senses the temperature of the transaxle fluid. This information is sent to the ECM for Viscous Converter Clutch (VCC) operation. The ECM will engage the VCC when fluid temperature is 200°F (93°C) or less, provided all other conditions have been met. If fluid temperature is higher than this, ECM will not allow VCC engagement until vehicle speed is about 36 MPH.
