HOW TO CHECK TRANSMISSION OIL - 2001 Isuzu Rodeo

Check to see if it is transmission oil or engine oil. If engine oil then the crankshaft oil seal needs to be replaced. If it is transmission oil, your torque converter maybe leaking. Before doing anything major try checking the hoses that connects from the transmission to the radiator. They could cracked or leaking. Some transmission use oil coolers and ATF filer on the transmission case itself. Check if they aree properly tightened.

most automatic transmission use a cooler located in a radiator tank to cool the transmission oil
check for oil pipe s in one of the tanks
Personally , I find that it is more efficient to use an air to air oil cooler for automatic transmissions as the radiators are running hard to cool both the engine and the hot oil from the transmission
As the transmission oil gets to excess of 150C the oil is never less than 100C from the radiator but using the external cooler , the temp can come down to ambient temp or less making for better oil life in the transmission

There are two types of transmissions in 1991 Toyota Corolla. Manual Transmission and Automatic Transmission.
1. Manual Transmission:
The transmission oil is checked through a level bolt which is provided to the left CV joint side in the middle of transmission. To check the oil level, park the car on a level floor, remove the level bolt with 22 mm or 24 mm spanner. If the oil starts coming out of this hole the oil level is considered OK. If not, top up the oil till it starts coming out and tighten the bolt. The recommended manual transmission oil grade is 75W/ 90W and total capacity is 2.4 Litres.

2. Automatic Transmission:
Warm up the engine, park the car on level floor, pull up the hand brake, gear lever stick in P, keep the engine start, let the radiator fan come on, take the auto-transmission stick out, wipe it with a clean dust free cloth, insert it in, again take it out, keep the stick in horizontal position and check the oil level. At operating temperature the auto-transmission oil level should be at upper level (Hot). If not, add oil to mach the mark. The recommended auto-transmission oil is Automatic Transmission Fluid (ATF) Dexron II, and total (drain and refill) capacity is 1.4 Litres.

WELL IF ITS ENGINE OIL SHOOTING OUT CHECK AROUND OIL PRESSURE SENDING UNIT AND OIL FILTER SEAL LEAKING OR OIL FILTER HAS A HOLE IN IT. IF YOU TALKING ABOUT TRANSMISSION CHECK TRANSMISSION COOLER LINES GOING FROM TRANSMISSION TO RADIATOR.

TRANSMISSION FLUID LEAKS,CAN BE FOUND AROUND PAN GASKET.CHECK PAN GASKET,IF IT LOOKS WET AND YOU SEE FLUID DRIPPING AROUND THE EDGE OF OIL PAN, REPLACE PAN GASKET, WHILE YOU REPLACING PAN GASKET REPLACE TRANSMISSION FILTER WHILE OIL PAN OFF.IF TRANSMISSION OIL PAN NOT LEAKING, CHECK TRANSMISSION OIL COOLER LINES GOING INTO RADIATOR YOU WILL LOOSE A LOT OF FLUID THERE ALSO TORQUE SHAFT SEAL WILL CAUSE HEAVY FLUID LEAK WHILE ENGINE RUNNING CHECK OIL COOLER LINES AND LOOK AT THE TORQUE AREA WHILE ENGINE RUNNING YOU WILL SEE FLUID POURING WHILE ENGINE RUNNING THE OIL PUMP PRESSURE WILL PUSH FLUID OUT AT THE LEAKING AREAS.

the oil reservoir could have damage. check for the other oil line.

TO DO A TRANSMISSION FLUID CHANGE YOU NEED HAVE TRANSMISSION FLUID ON HAND YOU NEED TRANSMISSION FILTER AND GASKET.YOU NEED 3/8 WRENCH THE RATCHET TYPE WITH METRIC SOCKETS. YOU NEED JACK TO RAISE VECHICLE SUPPORT VECHICLE ON JACK STANDS.YOU NEED A DRAIN PAN. ONCE YOU GET VECHICLE OFF GROUND.PLACE DRAIN PAN UNDER TRANSMISSION OIL PAN REMOVE OIL PAN DRAIN BOLT.LET FLUID DRAIN OUT IN DRAIN PAN THEN SCREW DRAIN PLUG BACK IN PLACE DONT OVER TIGHTEN.REMOVE OIL PAN AND GASKET. BESURE TO HAVE PAPER TOWEL ON HAND.MAKE SURE TRANSMISSION OIL PAN GASKET SURFACE CLEAN BEFORE INSTALLING NEW PAN GASKET. ONCE TRANSMISSION OIL PAN REMOVED. REMOVE THE OLD TRANSMISSION FILTER INSTALL THE NEW FILTER.THEN WITH NEW GASKET ON OIL PAN IN PLACE.OIL PAN NEED TO BE CLEAN SO THE GASKET ADHESIVE WILL HOLD PAN GASKET IN PLACE WHILE INSTALLING PAN AND GASKET TO TRANSMISSION.INSTALL OIL PAN BOLTS INSTALL THEM CRISS CROSS TORQUE PAN BOLTS TO 7 TO 10 FT LBS. LOOK IN OWNERS MANUAL FOR TRANSMISSION FLUID CAPACITY.BUY 10 QUARTS .TO BE ON SAFE SIDE SO YOU WILL HAVE ENOUGH FLUID ON HAND. IF YOU DONT HAVE NO TRANSMISSION FLUID CAPACITY. ADD 7.5 QUARTS FLUID.WAIT FOR 2 MINUTES.CHECK TRANSMISSION FLUID LEVEL ON DIP STICK. SHOULD BE ON THE FULL MARK.CRANK VECHICLE UP.LET IDLE FEW MINUTES CHECK TRANSMISSION DIP FLUID LEVEL IF DROPPED ADD LITTLE MORE.WHILE ENGINE IDLING GETTING WARM UP. KEEP EYE ON FLUID LEVEL.WHEN FLUID LEVEL STOP DROPPING. APPLY BRAKES HOLD FOOT ON BRAKES SHIFT THROUGH ALL GEARS TWO TIMES. THEN CHECK FLUID LEVEL SHOULD BE ON FULL MARK.CHECK FOR LEAKS WHILE ENGINE RUNNING.

LEVEL CHECK With Oil Level Gauge Fig. 1: Manual transaxle oil level check - with level gauge

1. Drive the vehicle to bring the transmission up to operating temperature.
2. With the engine stopped, remove the oil level gauge front the side case of the transaxle.
3. Check the color and smell of the oil. If it is black in color or smells burnt, further transmission service is needed.
4. Wipe off oil level gauge with clean cloth.
5. Fit the oil level gauge to the transaxle side case so that the threads rest on top of the case.
6. Remove the gauge and check oil level. The level should be between FULL and LOW level line.
7. If the level is below LOW mark, add oil until the proper level is reached.

With Oil Level/Filler Plug

1. Drive the vehicle to bring the transmission up to operating temperature.
2. Raise and support the vehicle safely.
3. Remove the transaxle oil level/filler plug.
4. Check the color and smell of the oil. If it is black in color or smells burnt, further transmission service is needed.
5. Transaxle oil level should be even with the bottom of the plug hole. If oil level is low, adjust oil level accordingly.
6. Install transaxle oil level/filler plug and tighten to 40 ft. lbs. (54 Nm).
7. Lower the vehicle.
