Transmission fluid leak

I have a 1993 Q45 infinity and it leaks from the transmission pan. I had the seal for the pan looked at and replaced. Now the car will not go in reverse. I got some seal treatment in it and it still leaks a little. What could this be?

Could be the bolt are loose or were over tightened and crushed the gasket.Could it be leaking from some other spot and running back while you drive? If so it may be the front seal.

    Check and make sure your bolts and screws are tight. This could be the problem. Or you still may have a hole in your pan. Also, have a check up on the gasket, thats one main need for the pan to be held on. Hope this helps!

Transmission seal leak... the leak is on the right side of the trany pan. do i just take the pan off then replace the seal?


Yes remove the old seal and install a new seal. Do not forget to service your transmission fluid back to the vehicles recommended amount. ( You can also replace your transmission filter since you already have the pan off too).

Transmission fluid is leaking how do i fix it


Hi Sandra:
Normally if oil or transmission fluid mixes with coolant it will turn milky looking like a milkshake. Your leak must be pretty fresh. from your description that it is coming out of the coolant overflow I am thinking you have a radiator transmission cooler leaking into the cooling system.

You will need a new radiator and possibly all the coolant hoses if they have become soft from the transmission fluid.

In most cases if your getting transmission fluid in the radiator it is cause by a bad transmission cooler that is built into the radiator and the fix is to replace the radiator.

The repair will change in price from where the leak is coming from. If the pan is leaking or the rear seal your looking at $100.00 or less. If the front seal is leaking then around $550.00. The most common leak is the pan gasket. Also if the transmission fluid and filter have not been replaced in the last 30,000 miles and the pan is leaking then I suggest doing this also why the pan is off .

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

Transmission is not "engaging" at all- fluid


I'm guessing you mean transmission fluid poured out? That would certainly explain why it won't move. The most common leak point for older automatic transmission cars are the transmission cooler lines. They run from the radiator to the transmission (the cooler is built into the radiator) and they are made of steel so they are prone to rust. I would start looking there. The other leak points would be the lower pan, axle seals, and where the case bolts together. Take a look at the radiator and you should see some small steel lines bolted to the radiator. Follow them and look for heavy rust that is wet with fluid.

Leaking transmission fluid


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.

My transmission leaks what should i replace


There are at least 5 places on the Automatic transmission that can over time, and mileage develope fluid leaks. Front converter seal at the front of the transmission,pan gasket in the center,dipstick tube o ring at the center on one side ,speed sensor o ring,and the tail shaft seal at the rear,of the transmission.
Place a flat piece or huge card board,under the engine and transmission,after driving you will see where the fluid,red in color is dripping. Its easier to spot exactly where the leak is comming if you can look under the car,while it is running, The easiest leak is the pan gasket,the dipstick tube, and the speed sensor,then the rear housing tail shaft bushing and seal.
If the front seal(converter seal) is leaking the transmission will need removed,and the seal,and maybe even the front pump bushing Replaced,it would be a good idea to replace the bushing esp if it has high mileage,80,000 or 100,000 miles of use.Change the fluid and the filter,while repareing the leak or leaks.Is a good idea.

Transmission fluid leaking


Bars leak is ok, but if it is a seal, you'll need to drop the tranny pan and replace it. I don't know about Mercedes, but usually you have to remove the exaust pipes to take the pan off.
