Toyota Sienna Transmission Replacement Cost

In 2004, Toyota Sienna owners began to experience problems with their transmissions. Many owners reported that their transmissions would slip or jerk, and some even said that their Siennas would not shift into reverse. In response to these complaints, Toyota issued a voluntary recall of Siennas in 2005. The recall affected Siennas from the 2004 and 2005 model years, and Toyota offered to replace the transmission at no cost to the owner.

Despite the recall, many Sienna owners continued to experience transmission problems. In 2007, Toyota issued an extended warranty for Sienna transmissions, covering repairs for up to 10 years or 150,000 miles. This warranty was in addition to the original 3-year/36,000-mile warranty, and applied to Siennas from the 2004, 2005, and 2006 model years.

In 2009, Toyota issued another recall for Sienna transmissions, this time affecting Siennas from the 2007 and 2008 model years. Once again, Toyota offered to replace the transmission at no cost to the owner.

Today, the Toyota Sienna is one of the most popular minivans on the market, and its transmission problems are a thing of the past. If you own a Sienna, you can rest assured knowing that Toyota stands behind its product and will take care of any transmission problems you may experience.

What Are The Symptoms Of A Failing Toyota Sienna Transmission?

When your Toyota Sienna starts to experience transmission problems, it will often exhibit a few specific symptoms. If you notice any of the following, it’s time to have your transmission checked out by a professional.

1. Slipping Gears

One of the most common signs of a failing transmission is when the gears start to slip. This can happen when you’re driving and suddenly the engine revs but the car doesn’t speed up. Or, you may be trying to accelerate and the car seems to hesitate before finally catching up.

2. Leaking Fluid

Another telltale sign of transmission trouble is leaking fluid. Transmission fluid is typically red or brown and will often have a sweet smell. If you see a puddle of fluid under your car or notice that the level of fluid in the dipstick is low, it’s time to take your car to a mechanic.

3. Burning Smell

When transmission fluid gets low, it can cause the gears to overheat and start to grind. This will often cause a burning smell to come from the car. If you notice this, it’s important to pull over and call for help.

4. Check Engine Light

Sometimes, a failing transmission will cause the check engine light to come on. If this happens, it’s important to have your car checked out as soon as possible.

If you notice any of these symptoms, it’s important to take your car to a mechanic right away. Ignoring the problem will only make it worse and could eventually lead to a complete transmission failure.

How often does a Toyota Sienna transmission need to be replaced?

This is a question we get a lot at our service center. And it makes sense- your transmission is a vital part of your car, and it’s not exactly cheap to replace.


How often should you replace your Toyota Sienna’s transmission?

The answer, unfortunately, is not a simple one. It depends on a variety of factors, including:

• How you drive

• Where you drive

• The roads you drive on

• The condition of your transmission

That said, there are a few general guidelines you can follow.

If you take care of your car and drive it sensibly, you can expect your transmission to last a long, long time. We’re talking hundreds of thousands of miles here.

However, if you’re hard on your car or don’t take good care of it, you can expect to replace your transmission much sooner. We’ve seen transmissions fail in as little as 50,000 miles.


What’s the best way to take care of your transmission and make it last?

Here are a few tips:

• Check your fluid levels regularly and top off when needed

• Flush and replace your fluid every 50,000 miles

• Don’t tow more than your car is rated for

• Get your car checked out if you notice any strange noises or behavior

Following these tips should help you get the most out of your transmission. But even if you do everything right, there’s still no guarantee that your transmission will last forever.

At some point, you will likely need to replace your Toyota Sienna’s transmission. But if you take good care of it, you can help it last a long time.


The average cost to replace the transmission in a Toyota Sienna is between $3,500 and $4,000. This cost will vary depending on the year, make, and model of your vehicle, as well as the location of the transmission replacement.
