How do i fix a transmission leak on a 06 hyundai azera at the top where it connect to motor?

Make sure the fluid level is at the proper height. Most often when the top of the transmission is wet with ATF (Automatic Transmission Fluid) it is overfull and "venting" through an overflow passage.

I have a 2000 silverado 2500 4x4 auto transmission. I noticed today a puddle under the tranny. I looked at the yranny and found a black rubber tube attached to a hanger but not connected to anything...

Hi Chris. Not very familiar with these particular transmissions, but if the tube is "dripping" fluid and not "spraying" fluid, I would have to say that this tube may be some sort of pressure relief or overflow as you had suggested. Did you have the transmission serviced or add fluid recently? If so, I'd guess that it may have been slightly overfilled. As you drive your truck and the fluid in the transmission heats up it expands and fluid pressure can/will increase. If the system pressure is too high it can do as much internal damage to your transmission as running low on fluid will. This tube may the outlet of a pressure relief device. Keep an eye on it... if it persists I'd have someone qualified take a look.

Power steering fluid bubbles up thru the resevoir

Hello, If it is overflowing fluid you have a problem in the pump or reservoir drain(supply) line. If there appears to be air bubbles in the reservoir, look at the supply line that comes off of the bottom of the reservoir.

The supply line goes to the front of the truck (You did not indicate vehicle) and there usually is a small fluid cooler that it attaches to. The supply line itself has both metal and rubber sections and where the supply line is clipped to the frame with plastic clips it corrodes. The line has a habit of rusting in this fixture and when a small hole is formed, it will draw in air. Often the fluid will leak against the frame and be concealed and blown off from the wind passing under the vehicle when driving.

The fluid flows in a loop, and if the fluid is collecting on top by the reservoir, it is not draining and flowing fast enough to clear the reservoir. You could also be overfilled and as the fluid heats up it will expand. Check your fluid levels.

I hope my solution is very helpful and if you need Model specific info, please include which Model you have.

I have a 2000 Expedition and I believe I have a coolant leak and I can see that all the coolant that I add to the coolant plastic tank trickles down over transmission housing next to the oil pan. What...

Don't overfill the coolant resevoir when adding coolant. There is a cold and hot fill line on the resevoir. Excess coolant will spill out through overflow tube on resevoir.

I have transmission fluid leaking on the inside of my car under the dashboard!!!! I can see a transmission line coming from transmission and it goes into the fire wall it is a 5 speed manual transmission....

this is the line going from your master cylinder i believ. take it to a shop for repair unless you know how to replace it. and be vary vary cautious bringing it to a shop because if i am right you will loose your clutch and not not be able to get it into gear if you stop. and if you let me know what year it is i can maybe tell you how to replace this your self.
hope this helps you and please rate me if you would.

How to remove the windshield washer reservoir?

I'm guessing you may have figured this out by now but I had to do it recently.

First drain the fluid from the reservoir. Then remove the car battery. Then the battery tray. I believe it was held on with about 4-5 of which threads into a retainer clip on the reservoir itself. Now you have cleared the way to remove the reservoir. It is held in by a few bolts that are accessible from the top side and bottom both. You will have to get on your back and get to those with a ratchet. It will be obvious where these are upon inspection. And finally there is a plastic retainer that goes through the plastic inner fender into a retaining hole in the reservoir. Firmly but carefully separate it from this plastic'll probably have to reuse it. After you do that the reservoir is free to move. Unhook the wire harnesses to the fluid pumps. Unhook the lines to the to pumps. Now just pull the reservoir out through the bottom of the car.

Coolant resevoir

There is a feed hose under there that goes to the bottom of the reservoir. Look around the edge of the reservoir, and you'll see three locating screws, philips head. Remove these and you can tilt the reservoir up and out of the way to look and see if you can see a disconnected hose underneath.
