The automatic transmission fluid and fi
lter should be changed every 15,000
miles (24,000km) if your Camaro is driven in heavy city traffic in hot weather, in
hilly or mountainous terrain, frequent trailer pulling, or uses such as found in
taxi, police car or delivery service. If your Camaro is driven under other than
listed above conditions, change the fl uid and filter every 30,000 miles
(48,300km).
1. Raise and support the car on jackst ands. Place an oil catch pan under
the transmission.
2. Remove the oil pan bolts fr om the front and sides only.
3. Loosen rear oil pan bolts approximately 4 turns.
WARNING - Do not damage the transmission case or oil pan sealing surfaces.
4. Lightly tap the oil pan with a rubber mallet or gently pry it downward to
allow fluid to drain.
5. Remove the remaining oil pan bolt s, then remove the oil pan and pan
gasket.
6. Remove the filter and seal.
7. Clean the transmission case and oi l pan gasket surfaces with suitable
solvent and air dry. Make sure to re move all traces of the old gasket.
To install: 8. Coat the seal with a sm all amount of Transjel®.
9. Install the new s eal onto the filter.
10. Install the new filter into the case.
11. Install the oil pan and new gasket.
On 1991 and later vehicles, inspect t he oil pan screws and washer assemblies.
The screws must not be used if the coni cal washer is reversed. Failure to
replace the screw and washer assembly may result in improper fastening of
system components.
12. Install the oil pan bolts and tighten them to 12 ft. lbs. (16 Nm).
13. Lower the car.
14. Fill the transmission to proper level with Dexron®II fluid.
15. Check cold fluid level reading fo r initial fill. Do not overfill the
transmission.
16. Follow the fluid level che ck procedure described before.
17. Check the oil pan gasket for leaks.

DRIVE AXLE
FLUID RECOMMENDATIONS
On standard differential rear axle a ssemblies, use SAE 80W-90 GL-5 (SAE
80W GL-5 in Canada) gear lubricant. On limited slip differential rear axle
assemblies, use 4 fl. oz. of limited slip differential additive lubricant and SAE
80W-90 GL-5 gear lubricant.

LEVEL CHECK
Fig. 1: Removing filler plug to check rear axle lubricant
The gear lubricant in the drive axle should be checked every 12 months or
15,000 miles (24,000km).
1. Raise the car and support on jackstands as close to level as possible. \
2. Remove the filler plug from the side of the drive axle housing.
3. If lubricant begins to trickle out of the hole, there is enough and you need
not go any further. Otherwise, carefully insert your finger (watch out for
sharp threads) and check to see if the lubricant is up to the edge of the
hole.
4. If not, add oil through the hole until the level is at the edge of the hole.
Most gear lubricants come in a pl astic squeeze bottle with a nozzle;
making additions simple.
5. Install and tighten the filler plug.
DRAIN AND REFILL
The rear axle should have the gear lubricant changed every 7,500 miles
(12,000km). If equipped with a limited slip differential, be sure to add 4 oz.
(118mL) of GM lim ited slip additive part No. 1052358.
1. Raise the car and support on jackst ands. Place a container under the
differential to catch the fluid.
2. Remove the bolts retaining the par king brake cable guides and position
aside.

3. Clean all dirt from
the area around the cover. Re move the bolts retaining
the cover to the housing. Pry the co ver from the differential housing and
allow the fluid to drain into the catch pan.
To install: 4. With the cover and housing washed free of oil and gasket material, apply sealer to the mating surfaces.
5. Using a new gasket, install the cove r and torque the bolts to 20 ft. lbs.
(27 Nm) in a clockwise pattern to in sure uniform draw on the gasket. Fill
the differential with fluid through the fi ll plug and add limited slip additive,
as required.
6. Install the parking brake cable guides, if removed.
7. The fluid level shou ld reached a level within
3/8 in. (10mm) of the filler
plug hole. Replace the filler plug. Low er the car and inspect for leaks.
COOLING SYSTEM
CAUTION - When draining the c oolant, keep in mind that cats and dogs are
attracted by the ethylene gl ycol antifreeze, and are quite likely to drink any that
is left in an uncovered container or in puddles on the ground. This will prove
fatal in sufficient quantity. Always drai n the coolant into a sealable container.
Coolant should be reused unless it is c ontaminated or several years old (in
which case it should be taken to a recycli ng facility such as a service station).
FLUID RECOMMENDATIONS
When adding or changing the fluid in the system, create a 50/50 mixture of high
quality ethylene glycol antifreeze and water.
LEVEL CHECK
Fig. 1: Fluid level marks on the cool ant recovery tank. With a warm system,
coolant level should be just below the FULL HOT mark on tank.

GM – CAMARO 1982-1992 – Repair Guide (Checked by WxMax) 792
The fluid level may be checked by obs
erving the fluid level marks of the
recovery tank. The leve l should be between the FULL HOT and FULL COLD
mark when the system is at normal operat ing temperature. When the engine is
cold, the fluid level should be above the FULL COLD mark on the reservoir. At
normal operating temperatures, t he level should be between the ADD and the
FULL marks. Only add coolant to bring the level to the FULL mark.
CAUTION - Should it be necessary to remove the radiator cap, make sure that
the system has had time to cool, reducing t he internal pressure. If the system is
opened while the engine is st ill hot, scalding fluid and steam may be blown out
under pressure.
