transmission pan continues to leak after replacing seal, took the pan off twice now will not seal?
Tranny sprung a leak at back driver side corner between pan and tranny.
Pulled pan off installed cork type gasket with tranny gasket sealer. Filled tranny with new atv ……leaking in the same area just larger leak.
Pulled pan off again, used re-usable gasket with gasket sealer and still leaking?
I did check the pan for warps between screw holes, adjusted pan some, 1/16th inch out of level in spots.

Experienced mechanics share their insights in answering this question :
There has to be some problem with the mating surface on the transmission or the pan and seal. If there are any pieces of the old seal on the pan, the chances the pan will leak at that spot are pretty high. Look closely with a flashlight to see if there are any cracks along the mating surface or pan where the leak continues and clean the area well to be sure it is the pan and not a leak from higher up coming down on the pan. Many mechanics will use a scraped along the surfaces to make sure any debris is knocked off before adding a new seal and sealer. Also, allow the pan sealer you are using to cure for a couple of hours before adding fluid to the transmission. Consider hiring an experienced technician like one from YourMechanic who can come out to take a closer look and offer a more personal diagnosis.

Cars with automatic transmissions have a pan gasket designed to catch most fluids leaking from the engine. Over time, loose bolts or holes may occur, causing the transmission fluid in your parked car to leak. Sometimes impact can also damage the pan if a sharp object hits it.
Over tightening the bolts can easily damage the pan of a transmission. The flange of the transmission pan should be flat and have no bulges. Over tightening the pan bolts causes the flange to distort. Inspect the pan and make sure the flange is flat.
Pan Gasket Leaks
If they do not have a perfect dry seal, transmission fluid can leak from this area. This can happen due to normal wear and tear. In addition, if the gasket isn`t properly aligned when the transmission pan was installed, it can roll off of the surface it is supposed to seal, and this can create a leak.
Yes, Bar`s Leaks is one of the only transmission stop leaks that is compatible with all petroleum-based transmission fluids including synthetics. Use in regular automatic or manual transmissions.
Many people think that using stop leak products can save money by stopping a transmission fluid leak. Unfortunately after affects of using leakage stopping products come at a significant cost. Stop leak products can cause irreparable damage to your vehicle.
A puddle on the ground: The most obvious sign of a transmission leak is discovering a pool of transmission fluid under your vehicle. Most leaks start small, so check your regular parking spot often. A few drops aren`t necessarily a major problem, but it will be the sign that you have the start of a leak.
The torque converter pushes the transmission oil throughout the transmission. It`s basically a pump, and if this pump develops a crack, you`ll end up with a transmission leak. The needle bearings inside the torque converter can also get damaged and this, too, will cause a transmission fluid leak under your car.
7 to 9 ft-lbs…..not much at all. DON`T over torque or you`ll screw up the pan gasket. Take your time, as it does require a bit of dexterity to hold the pan up, keep the gasket in place and tighten 21 bolts at the same time.
How big are the metal shavings in the transmission pan? If they`re small enough they look like fuzz, nothing`s wrong. But if the fragments are large enough you can pick them up and feel their sharp edges, you have a problem.
A transmission leak will not get better on its own. If it goes unchecked, vehicle operation will eventually be affected, and you may find yourself with an expensive repair. So, while it may be safe to drive with a leaking transmission, it`s not advisable, and you shouldn`t put off fixing the problem.
Permatex Automatic Transmission RTV Sealant is specially designed to withstand the harsh detergents and friction modifiers found in automatic transmission fluid that break down normal RTV silicones.
The TC leakage can be caused by the following reasons: ATF overheating, fluid shortage in the oil pump; Problems with the oil pump bushing, wear of the seal itself.

Poor fit or design. Another reason for premature transmission seal failure is poor structural design and, as a result, poor fit inside the unit. This type of seal failure typically occurs in aftermarket “knock-off” seals are installed instead of true OE components that are designed to fit the original transmission.
When the torque converter starts malfunctioning, you may feel shuddering and even slipping in overdrive. You usually notice your car shuddering because it feels like it`s vibrating. Your car will vibrate even when you`re not going very fast. The shuddering makes the car lag and is very noticeable.

My 1993 Ford f-150 is leaking transmission fluid from the rear end of the pan. ive already replaced the gasket as well as the pan
ANSWER : There are two different places it may be leaking if not from a cracked housing at one of the pan bolt holes. The rear tail shaft housing or the shift linkage shaft seal could be leaking. Have the areas cleaned and vehicle run on a lift to isolate where it is coming from.
Are thse current and relevant prices for this service, and how long does it take? REPLACE AUX VACUUM PUMP (OIL LEAKING FROM A
ANSWER : Hi there. It really depends on who provided you with this diagnosis as to how long the repairs would take to complete. In regards to not including the seals listed at the bottom, this is not advised. The seals protect the components from leaking and will also reduce the potential of overheating on your vehicle.
Oil leak turned into oil cooler replacement
ANSWER : Hi there. There are two types of oil coolers on many cars, the engine oil cooler and the transmission oil cooler. It’s not a part that typically wears out frequently, however, sometimes leaks can develop due to being hit by an object or seals and gaskets failing.
As far as how long an oil cooler will last, that’s hard to answer due to the fact that it’s a mechanical part that can fail for many reasons that simply can’t be predicted. However, if it were to happen again, one of our local ASE certified mechanics can complete the oil cooler replacement for you.
Rear Axle Seal Replacement – What type seal?
ANSWER : Hi there, thanks for writing in. I recommend buy the Toyota OEM part. Although we could go into high detail as to the precise technical differences amongst the various and competing aftermarket seals you are describing, such will not change the conclusion at all. Generally speaking, aftermarket parts are NOT as good as the factory OEM parts. Large car manufacturers spend hundreds of millions of dollars, indeed billions, developing the technologies used in these vehicles and ALL of the parts are extraordinarily carefully engineered to fit very precisely and perform specific functions. In the aftermarket, they try to duplicate that, but more often than not, it does not work. Toyota OEM quality in particular is not duplicated well, if not at all, in the aftermarket.
Transmission additive to stop pump seal leak I don’t want to spend $750 on repairs will a transmission stop leak fix it
ANSWER : You can certainly use transmission stop leak, however depending on how bad the leak is or the amount of pressure coming from the leak, this may be only a temporary fix. I would suggest having a professional from YourMechanic come to your location to take a look at the vehicle.
2013 Ford Focus Transmission Issue. Is it worth keeping the car?
ANSWER : Hi There,
This is a known issue in this generation Ford Focus and some Fiestas with the "Power Shift" transmission and there have been numerous recalls and lawsuits. Although, it is would be difficult to determine how much longer your transmission will last given the fact that you have many new parts, I would not recommend junking the car as it may still provide some valuable life left for you. I would recommend taking it to the dealer to see if these parts may be covered under the recall.

Transmission axle sea
ANSWER : You didn’t mention that you had the axle replaced but if you did the new axle may be the wrong one for your car, or you may have to get the replacement axle and seal from the dealer.
This vehicle in particular may have had a certain year of seal and axle, which then changed during the following year or mid year. The only way to get it correct may require the specific dealer parts by using your VIN number, it’s the only way to get the correct ones if you keep having issues with aftermarket parts. I’d recommend having a certified mechanic diagnose it to help you find the right replacement for your axle shaft seal.
