How Much To Fix A Leaking Transmission

(Updated on April 15, 2021)

Your automatic transmission has lots of moving components and parts inside of information technology. Like with the parts of an engine, the transmission'due south moving parts will also generate a great deal of heat every bit they rub together.

This means that the parts of the transmission will need to be lubricated in a similar style that the engine needs to be lubricated. The only difference is the transmission will use transmission fluid as its lubricant instead of oil.

If you lot have an adequate corporeality of transmission fluid in your transmission, then it volition be able to lessen the amount of friction between components which in turn keeps the transmission cooler and operating as it should.

Causes of Leaking Manual Fluid

You tin normally wait until you drive anywhere from 60,000 to 100,000 miles before you need to change your automatic manual fluid. However, you could notwithstanding lose this fluid if a leak were to occur somewhere in the transmission organisation before the regular manual fluid change interval.

The most obvious sign of a transmission leak is if you notice a small pool of redish fluid underneath your car where the transmission case is. This ruby-red fluid is typically associated with manual fluid although former or burnt fluid will be more of a brown colour.

If you run across transmission fluid under your motorcar, y'all demand to take it seriously and fix the leak immediately. To help you spot exactly where the leak is coming from, here are the most mutual locations of automatic transmission fluid leaks.

i) Bad Manual Pan Gasket

Every automatic transmission vehicle has a transmission pan which stores the transmission fluid. The mechanical seal which rests in betwixt the pan and the transmission is called the transmission pan gasket.

This component is what prevents manual fluid from escaping as it is transferred into the transmission from the pan. If the gasket were to get damaged or cracked, and so it will cause transmission fluid to leak out. What may start off every bit a tiny scissure will likely go worse unless this gasket is replaced.

2) Cracked Torque Pump

The torque pump is what circulates the manual fluid throughout the entire manual system. If the pump were to get damaged, so it would either cause the fluid to cease circulating or it would cause the fluid to leak from there.

Either way, you will definitely accept a big problem on your hands that needs to get fixed fast.

iii) Damaged Transmission Pan

The transmission fluid pan in most cases will last the lifetime of a vehicle. Yet since the pan is fastened to the transmission via fasteners and probable has at least 1 drain plug, a leak can easily occur if any i of these parts were to become loose or damaged.

In fact, the pan itself could go damaged if yous were to get into an accident or accidentally run over a large rock that your transmission pan can't clear. It may cause a dent or crack in the pan which you may not even be enlightened of. If you discover your manual pan is the source of your leak, replacing it is usually the all-time option.

4) Cracked Transmission Seals

The transmission seals of an automatic transmission keep the hydraulic pressure in-line. The but problem is these seals are constantly exposed to estrus as the transmission is in operation.

The seals volition eventually get to the bespeak where they will go worn out and crack from all this long-term oestrus exposure. The seals will and then leak transmission fluid.

Whatsoever of the seals could be leaking this fluid, including the shifter housing seal, plug seal, tail housing seal, output shaft seal, and so on.

5) Cleaved Fluid Line

The transmission'southward fluid line is made to be durable considering it is constructed from aluminum or steel cloth. However, if information technology were to get damaged because of excessive heat exposure, the line will eventually crevice and then it volition leak transmission fluid. Even the aluminum or steel cloth won't exist strong enough to forestall this.

Transmission Leak Repair Cost

If you have an automated transmission that is leaking fluid, the cost to repair the leak will depend on where the leak is coming from. On average you lot can expect to pay anywhere from $100 to $250 for the repair task.

However, if the forepart seal is causing the leak, it will likely increment your repair cost quite a bit since the mechanic will need take out the manual beginning to get to it.
