The leak has been around the transmission transfer case. The underside of the vehicle has been cleaned down and the transmission oil level checked and is OK. I have since travelled 40 kms and there doesn't appear to be any leaking. Could the transfer case been over filled and relieved from the system? The vehicle has 100400 on the clock and I have owned it since new.

That is usually the number one problem of overfilling. The transfer case has a vent tube and when overfilled, the excess fluid will go out the vent tube and all over everything underneath the car.

SOURCE: oil level system

It may seem obvious but do not operate the engine with it overheating as this can lead to more trouble including a cracked engine block.

Low engine oil pressure is a problem because if it exists, the critical engine parts may not get lubricated properly and may fail. Since you have ruled out external leaks, here are some possibilities:

Clogged oil filter or obstruction in the system

Loose wire or faulty oil pressure or oil level sending switch/sensor.

Possible blown head gasket. This is a serious problem that might be accompanied by white or blue exhaust smoke and a burnt coolant or oil odor. Check for oil contamination with coolant. The dipstick may show a brown milky film/sludge or smell like burnt coolant indicating contamination.

Engine oil pump is possibly bad. This is a serious problem. It's usually time to swap out or rebuild the engine, particularly if it has many miles.

Possible but unlikely in this case is a problem with PCU (Power Control Unit) that runs the Information Center. PCU problems are often indicated by getting other unrelated errors on the info display or "DATE NOT AVAILABLE" for extended periods when you start the car.

You did not mention the Check Engine/Service Engine Soon light being on, but if so I would get the trouble codes read at the OBD II connector. The codes might indicate a sensor problem. Some auto stores do this for free. Either way, I would assume the worse case scenario (bad oil pump) and address it immediately. Unfortunately, due to the complex nature of the car, most things are not easy to diagnose and repair by the do-it-yourselfer. Hopefully though it is just a sensor but with a temperature rise, I would be careful.

Best of Luck!

The transmission fluid is not to be checked or touched unless there is a malfunction in the system and the fluid has to be drained to repair it. The transmission is sealed form the factory and the fluid lasts the lifetime of the unit.

SOURCE: 2000 Jeep Cherokee Transfer Case Leak

Clean the area off with a degreaser and watch it. If it is an input or output seal leaking, you unbolt the drive shaft going into the case, remove the nut that holds the u-joint flange on, pry the old seal out and tap the new seal in (be careful not to tap too hard or the seal will bend)

Where do i find my transfer case and what fluid does it use
1. Be sure to run your car (in 4WD) for about 5-10 minutes or so to warm the oil up and be sure to park on a level ground.First we need to gather our materials. This is what I used for my oil change:Initial expenses
  • Oil Catcher - $10 at Pep Boys
  • Fluid Pump - $5 at Pep Boys
  • 24mm wrench or ratchet (assumed ownership)
  • 12mm? and 14mm? sockets to remove skidplate
Transfer Case Change Expenses
  • 3 Qt 75W90 Gear Oil - $21
  • (I used Redline from myoilshop.com)
tcase1-nggid03733-ngg0dyn-320x240x100-00f0w010c010r110f110r010t010.jpg 2. Locate the Transfer Case.
Remove the Fill Hole plug first, then place your oil catcher in position, and remove the drain hole plug.
While the oil drains, clean off the drain plug.
tcase2-nggid03734-ngg0dyn-320x240x100-00f0w010c010r110f110r010t010.jpg
3. When finished draining, replace the drain plug, and proceed to pump the fluid into the fill hole.
I filled until the fluid overran, but you can check the fluid by sticking a pinky into the hold and checking the level.
Replace the fill hole plug, and done.

Transfer case is overfull
You can drain to the appropriate level and recheck after driving. The rear main on the transmission may be leaking into the t-case causing the condition. Advise checking the transmission level. Engine hot, vehicle level and running in park or neutral. This could be a good indication of leakage if low.

My 1988 surburban will not shift into overdrive any suggestions
It's probably a valve body problem, shift solenoid, stuck valve or something of that nature. Is the fluid fairly clean and is it full? To check the fluid level the engine must be idling and the transmission must be in park. The fluid should be Red, not brown or black. Those vehicles have a nasty habit of the seal going bad between the transmission and transfer case (4X4 only) and it will dump about 2 quarts of transmission fluid into the tranfer case. This leaves the trany dangerously low on fluid but, you never know it because there is no fluid leaking on the ground. Check the transfer case oil, is it way over full, if so that seal is bad.

What is the capacity of the transfer case and exactly what fluid do i use
GM Full-Size Trucks 1980-1987 Repair Guide

Transfer Case - FLUID RECOMMENDATIONS
The type of lubricant used in the transfer case varies with model year and type of transfer case. Refer to the list below for the type that applies to your truck.

1980
Conventional transfer cases require SAE 80W or SAE 80W-90 GL-5 gear lubricant.
Full time systems use SAE 10W-30 or 10W-40 engine oil.
1981
Conventional transfer cases require DEXRON®II transmission fluid.
1982-85
All transfer cases require DEXRON®II transmission fluid.
1986-87
All transfer cases except the K30/35 series require DEXRON®II transmission fluid.

For fluid recommendations for the K30/35 transfer cases refer to the owner's manual. LEVEL CHECKS

fb6e8b4.jpg
Fig. Model 208 Transfer Case

Check the four wheel drive transfer case lubricant level every 4 months or 6,000 miles.
  1. With the truck parked on a level surface and the parking brake firmly applied, remove the filler plug from the rear of the transfer case (behind the transmission). Be careful not to take out the drain plug at the bottom.
  2. If lubricant trickles out, there is enough. If not, carefully insert a finger and check that the level is up to the edge of the hole, EXCEPT in full time four wheel drive cases should be 1 /2 in. below the hole.
Lubricant may be added, if necessary, with a funnel and tube, or a squeeze bulb.



DRAIN AND REFILL
Part Time Systems
No intervals are specified for changing transfer case lubricant, but it is a good idea for trucks that are worked hard or driven in deep water.
  1. With the transfer case warmed up, park on a level surface and apply the parking brake.
  2. Slide a pan of a least 6 pts. capacity under the case drain plug.
  3. Remove the filler plug from the rear of the transfer case (behind the transmission). Remove the drain plug from the bottom.
  4. Wipe the area clean and replace the drain plug.
  5. Add lubricant with a suction gun or squeeze bulb. Conventional transfer cases require SAE 80W-90 GL-5 Gear Lubricant.
  6. When the lubricant level is up to the bottom of the filler hole, replace the plug.
Full Time Four Wheel Drive
The full time system requires oil changes at regular intervals, according to the amount and type of work done by the unit. Trucks used for normal on-off road work should have the transfer case oil changed at 24,000 mile intervals. When used for heavy duty work, trailer towing, snowplowing, and the like, the interval should be halved to 12,000 miles. If the truck is exposed to extremely dusty or muddy conditions, the oil should be changed at 1,000 mile intervals.
The transfer case oil must be hot before changing. Drive the truck until the engine has reached normal operating temperature, and park on a level surface.
  1. Slide a pan of at least 8 pts. capacity under the case drain plug.
  2. Remove the filler plug.
  3. Remove the lowest bolt from the front output shaft rear bearing retainer cover, and allow the lubricant to drain. Be careful; the oil will be hot. There may be a drain plug. If so, remove that instead.
  4. Remove the six bolts on the left (driver's) side of the case which secure to P.T.O. (power take-off) cover. Remove this cover and allow the lubricant to drain out.
  5. Remove the speedometer driven gear from the upper left rear corner of the case.
  6. Use a suction gun to remove as much lubricant as possible from the case cover location and the speedometer gear location.
  7. Install the speedometer driven gear, the P.T.O. cover, and the lowest bolt or drain plug.
  8. Add approximately seven pints of oil through the filler plug opening. The proper oil to use is 10W-30 or 10W-40 engine oil.
  9. Check the fluid level and add sufficient oil to raise the level to 1 /2 in. below the filler plug opening. Replace the plug, and wipe the surfaces of the case and skid plate to remove any excess oil. Drive the truck and check for leaks.

I really hope help ypou woth this (remember rated this help) Good luck.
