Question about 1994 Jeep Grand Cherokee

2 Answers

I just did a few repairs all at once. I replaced the oil pan gasket, oil filter and oil. I replaced the transmission fluid filter, transmission pan gasket and transmission fluid. I put in new spark plugs, spark plug wires, rotor and rotor cap. I flushed the cooling system and changed the heater hoses, the upper & lower radiator hoses, the temperature sensor and the thermostat. I also replaced the valve cover gasket. When the engine is started now. There is a loud tapping noise that seems to be coming from the valve cover area. All the fuses are good. The check engine light stays on. The oil pressure gauge reads 50, but when I put a cloth under the oil filler cap and started the engine it remained clean. Is the valve compartment not getting any oil and what could be the problem?

The tappets are usually oiled via hydraulic lifters that pump oil up the push rods. I'm assuming you have the gas engine V-6 or V-8. When you changed the valve cover gasket(s), did you do anything else under the valve covers? It seems unlikely that none of the hydraulic lifters would be pumping, but it's possible one of them has failed. It would be OK to take off the cover from the noisy head and run the engine briefly to see what's happening. Just drape some rags around the area to catch the oil that will splash. Let us know what you see, if you decide to try this.

I would guess one of the valves are sticking or the lifters, but to me it sounds like the oil pump is either clogged or not working. Which would explain the engine light and the tapping sound. I hope this helps Tim

Bad transmission seal on a 2002 ford explorer


Drain the Transmission Fluid and Replace the Filter
Raise the car with ramps or a floor jack and support it with jack stands. Find the lower cover of the torque converter housing. Turn the torque converter until you find the drain plug. Place a drain pan beneath the drain hole, remove the plug and drain the fluid.
Remove the cooler lines at the transmission and flush them with compressed, low pressure air. Be careful during this step; fluid may shoot from the other cooler line.
Place a large drain pan beneath the transmission. Loosen the retaining bolts on the oil pan with a socket wrench until they are within a few turns of removal. If the seal doesn't break on its own, gently tap it with a rubber hammer. Fluid will drain from the edges of the pan.
Remove the pan retaining bolts when the fluid stops draining. There is still transmission fluid in the pan. Hold the pan carefully and drain as much as you can into the drain pan.
Scape the old gasket material from the mating surfaces on the oil pan and the transmission. Discard the old gasket. Clean the magnet in the pan. Clean the pan and the mating surfaces with a solvent and a clean, lint-free cloth. Replace the magnet and allow the pan to air dry.
Employ a socket wrench to remove the bolt that holds the filter onto the transmission. Some models may have two bolts. Pull the filter and any old seals or gaskets from the transmission. Install a new filter assembly, including any required seals or gaskets.
Put a new gasket on the oil pan and reinstall it on the transmission. Tighten the retaining bolts to 79- to 119-inch pounds with a torque wrench. Replace the cooler lines on the transmission and the drain plug on the torque converter.

Change transmission fluid and filter 1998 mercury mystique


You will need to buy a "TRANSMISSION FILTER KIT," which will include a new transmission filter, uptake gasket, and pan gasket for your transmission. (They run about $20 or less on eBay.) Once you have done that, you will need to hoist the vehicle, and CAREFULLY remove the transmission pan by loosening one bolt a little at a time without removing them, and breaking the old gasket free (hopefully without making too much of a mess of transmission fluid). About half of the transmission fluid (about a gallon and a half) will be in the pan (the rest in the torque converter). It is usually sufficient to replace just the amount of oil in the pan (otherwise you need to remove the torque converter inspection plug on the bell housing and crank the engine to expel the seal, draining the other half of the fluid, then replace the bell housing seal).
Once you have drained away the transmission fluid in the pan, CLEAN THE PAN THOROUGHLY WITH A SHOP TOWEL, and carefully remove the bolts that secure the filter to the transmission valve body. (As I recall it is four 10mm bolts... but not sure on your year model).
Remove the filter, and remove any remnants of gasket on the uptake chamber between the filter and the valve body. MAKE SURE YOU REPLACE THE SMALL GASKET AT THE TOP OF THE FILTER WITH A NEW ONE, OTHERWISE THE TRANSMISSION WILL SLIP DURING THE 1-2 SHIFT DUE TO AIR BEING SUCKED-IN (been there).
Check for correct torque specifications for the filter mounting bolts before tightening them and DO NOT OVER-TIGHTEN THE RETAINING BOLTS.
Once you have replaced the filter, and your pan is clean, scrape away all remnants of gasket material from the mounting surfaces, and position the new filter. (This is easier if you use a tiny amount of silicone RTV to hold the gasket in place and keep it aligned with the pan mounting holes).
Replace the pan, tighten the bolts to spec, re-fill the transmission with the appropriate amount of NEW ATF, then test.

Change transmission oil


Hi Peter, If your Camry has an automatic transmission, for normal driving the auto fluid should be changed every 40,000km, there should be a drain plug on the transmission pan that takes a 10mm hex drive or 17mm socket to undo. You have two choices after driving the car onto ramps or jacking up and supporting on jack stands so you can safely get under the car. 1 - You can loosen and remove the transmission drain plug to let the auto fluid drain out into a container (careful not to lose the sealing washer) refit and tighten the drain plug and washer again. Remove the auto transmission fluid level dip stick, using a suitable funnel pour about 2.5 litres of suitable new auto trans fluid back into the transmission via the dipstick tube (I believe they take dexron 2 of 3 type fluid). Start the car and move it onto a level surface. With the engine running, handbrake on and brake pedal applied, shift the transmission from park through every gear selection slowly into 1st gear, then back to park. Leave engine running. Wipe the dip stick & insert it back into the dip stick tube fully, remove and check where the fluid level mark is on the end of the dipstick. If the fluid level indicates low or does not show at all, add 100ml of additional fluid and recheck the level till the fluid reaches the full mark on the dipstick. 2 - The second option is everything in the first option but includes replacement of the transmission filter and pan gasket. I would only do this if the car had travelled high km or the pan gasket was leaking. At the point where you've drained the old fluid into a container and refitted the drain plug and washer, remove all the transmission pan bolts and the transmission pan. If you have the time to let the fluid drain overnight prior to removing the pan it's a good idea because once the pan is removed, fluid will continue to drip from the transmission. You'll need to remove the old pan gasket, some may be stuck to the pan and or transmission, a razor blade type gasket scraper can be good for this but be careful not to scratch either surface when cleaning off the old gasket. Remove the bolts/nuts that hold the transmission filter onto the bottom of the transmission. Careful caus more fluid may drain out of the transmission or filter once removed. Fit the new filter and filter tube gasket & bolts/nuts, careful not to over tighten. Fit new pan gasket, pan and bolts. Continue with fluid filling procedure from option 1. I would suggest you only use option one and remember to double check the drain plug is tight. Also, remember to dispose of the old fluid correctly. Cheers

Need to change the transmission filter how and where is it located


Fluid & Filter Change Under normal service (moderate highway driving excluding excessive hot or cold conditions), the manufacturer feels that automatic transmission fluid should not need periodic changing. However, if a major service is performed to the transmission, if transmission fluid becomes burnt or discolored through severe usage or if the vehicle is subjected to constant stop-and-go driving in hot weather, trailer towing, long periods of highway use at high speeds, fluid should be changed to prevent transmission damage. A preventive maintenance change is therefore recommended for most vehicles at least every 90,000 miles (145,000 km).
Although not a required service, transmission fluid changing can help assure a trouble-free transmission. Likewise, changing the transmission filter at this time is also added insurance.
  1. Raise the car and support it securely on jackstands.
The torque converters on some transmissions are equipped with drain plugs. Because it may take some time to drain the fluid from the converter, you may wish to follow that procedure at this time, then come back to the pan and filter removal.

980822b.gif
Before removing the transmission fluid pan, insure that the area is clean of dirt and debris

2. Place a large drain pan under the transmission.

378093c.gif
Loosen all of the pan attaching bolts to within a few turns of complete removal


  1. Loosen all of the pan attaching bolts to within a few turns of complete removal, then carefully break the gasket seal allowing most of the fluid to drain over the edge of the pan.
CAUTION DO NOT force the pan while breaking the gasket seal. DO NOT allow the pan flange to become bent or otherwise damaged.

  1. When fluid has drained to the level of the pan flange, remove the pan bolts and carefully lower the pan doing your best to drain the rest of the fluid into the drain pan.ea833e6.gif


Once the pan is removed, discard the old gasket and insure that the mating surfaces are clean

9aa0aea.gif
Inspect this magnet inside of the pan for any large pieces of debris. A light gray coating is normal

11c6ddb.gif
Clean the pan thoroughly with a safe solvent and allow it to air dry

5. Clean the transmission oil pan thoroughly using a safe solvent, then allow it to air dry. DO NOT use a cloth to dry the pan which might leave behind bits of lint. Discard the old pan gasket.

22d9261.gif
The transmission filter is secured by a mounting bolt (arrow). Some models may use two bolts

097949a.gif
Remove the filter mounting bolt ...


d9f5189.gif
... then pull the filter free from the transmission

6. If necessary, remove the Automatic Transmission Fluid (ATF) filter mounting bolts, then remove the filter by pulling it down and off of the valve body. Make sure any gaskets or seals are removed with the old filter. The transmission usually has one round seal and a rectangular gasket.

7. Install the new oil filter screen making sure all gaskets or seals are in place, then secure using the retaining screws, if applicable.

Install a new pan gasket


8. Place a new gasket on the fluid pan, then install the pan to the transmission. Tighten the attaching bolts to 71-119 inch lbs. (8-13 Nm).

34bd906.gif
Fill the transmission with the proper amount of ATF

9. Add three quarts (six quarts if the torque converter was drained) of fluid to the transmission through the filler tube.
10. Remove the jackstands and carefully lower the vehicle.
11. Start the engine and move the gear selector through all gears in the shift pattern. Allow the engine to reach normal operating temperature.
12. Check the transmission fluid level. Add fluid, as necessary, to obtain the correct level.
