Leak between the automatc transmission and Engine. The Bottom isolator is soaked with oil and dripping, especially when under torque condition? Landcruiser 90 1999 Diesel 3 litre

Here is what you must do, pressure wash the engine and the transmission top and especially bottom of all grease and oil residue then install a bottle of special die that glows under a black light, drive the truck for a 10 or so miles and then put it on a car lift and check for the source of the leak with a black light. On this old of an engine the leak are likely all over the place.

Usually when a car does not turn over, as in starter motor fails to trn over engine, it is battery related, weak, so turn on your headlights and see if they are bright, then leave on and try to start engine, if lights dim, charge battery is first thing to do, then have battery checked, sure sign of battery going bad. Trans. fluid smell is probably a leak issue, so look under car for drips which sometimes hits exhaust which causes smell. Trans. fluid is rarely something you can smell other than when burning.

Lots of Camrys do this.

The oil will typically leak from the rear main bearing seal between engine and transmission, but that will appear at the bottom of the joint line, and will not reach the exhaust. This leak is expensive to fix and is usually left as is.

A leak from the cam cover gasket can drip into the exhaust.

The other typical leak is from the distributor shaft o-ring seal. This appears at the top of the join line between engine and trans, and can blow back onto the exhaust.

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.

You have to differentiate whether the oil leak is from the engine or the tranny. After determining where the source, you must isolate the specific area; timing belt area, the middle-between the engine and the tranny. This can be cheaply determine by placing white piece of paper underneath the engine and observe the droppings of oil. Oil leak repair can be costly-especially an oil starved engine, so isolating the source is essential and tear-down might required.
Due to the age of the vehicle, possible sources are the camshaft seal, crankshalf seal, oil pan gasket, crankshaft end seal,distributor o-ring, and valve cover gasket.
In addition, other oil leaks can come the transmission, and power steering pump and rack'n'pinion. Best to raise the vehicle and inspect undercarriage of vehicle.

If its on the drivers side of the car close to the front check the transmission oil cooler lines. Especially if the fluid is redish in color. You will see them if you look up under the vehicle on the drivers side. There will be to black hoses running between the transmission and the radiator. If they are wet/dripping you found the leak.

there is a small filler neck in frt. of the trany , with red cap on it. Brake the cap , there will be a plug under.
Proccedure : engine on idle , take of plug at the bottom of trany oil pan(with engine on idle!!!!! , if engine off , fluid will leak out) , use transfering pump to pump oil in to filler neck untill it starts leaking from bottom plug , wiat till it only drips , put bottom plug back in and torque it. Now you can shut engine off and seal filler neck.
Use only approved trany fluid .This trany takes syntetic fluid.

Red fluid it auto matic transmission fluid. The black cover is the bottom of the transmission where the transmission filter is. Most of the time.. unless you recently had the transmission filter changed is inthe hose area where the hoses fromthe radiator connect to the transmission.

It is still quite possible for your transmission pan gasket to be leaking. Most of the time people think that by just tightening up the bolts that they fix the leak when in fact the over torque the boltrs and it leaks even more. If the transmission pan gasket is leaking buy a new gasket making sure the bolts are tightened per the manufactures torques.

Thanks for using FixYa.

look at the valve covers, the valve cover gaskets have most likely hardened over the years and are not sealing now

willie05: sounds to me like you have a leaking rear main oil seal.
If the oil is dripping out at the bottom of the motor and appears to be sourced from where the back of the engine and the front of the transmission mate together, that is your problem. Sometimes if the leak has been going on for a while, the under side of the engine and transmission may be covered with oil because of the wind turbulence caused by the car in motion had been blowing it all over the under side. It may take you washing the under side if the motor off or getting it done, to spot the leak more easily.
A valve cover gasket leak will also cause oil to run dow the back of the motor. However, it usually won't get on the flywheel.
Good Luck. Let me know how things turn out.
