Can I drive with a transmission problem?

If your Toyota Sequoia can still make it up and down the road, you might say “It’s fine, I’ll just drive it until I can get it fixed”. But that is not always a good idea, depending on the symptoms. You see, there are a lot of (very expensive) moving parts inside of a transmission, and if something isn’t right, continuing to drive with a transmission problem could damage something else.

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

The overall lifespan of a Toyota Sequoia transmission largely depends on how well it was maintained. Factory design flaws also factor into this equation, along with how/how hard you drive. But on average, we’ve seen the Toyota Sequoia transmission last for between 130,000-180,000 miles. A high quality replacement transmission however, can last considerably longer if all of the factory design flaws have been addressed and the vehicle has been maintained.

How are Toyota Sequoia transmission issues diagnosed?

It is fairly easy to guesstimate what the root cause of your Toyota Sequoia transmission problems might be, but you won’t truly know unless you have the right tools and experience. A good mechanic or transmission repair center will be able to connect your truck to a computer and find out which diagnostic trouble codes (DTC’s) have been stored. Once they know what to look for, they can perform a visual inspection to verify the problem.

How is a Toyota Sequoia transmission replaced?

In order to replace your Toyota Sequoia transmission, the truck has to be lifted from the ground in order to gain access to all of the parts that will need to be unbolted. Then the transmission can be lowered to the ground (typically with a transmission jack), so the new transmission can be installed.

How to Solve Toyota Sequoia Transmission Problems

Solution A: Buy a Used Toyota Sequoia Transmission

The quickest way to fix your transmission problems is to simply buy a used transmission or used transmission. These can be found at most junk yards, and they often come with a 30-90 day warranty. However, there’s no way to determine the actual condition of the internal components, so you could be spending a bunch of money to have the exact same problems. Plus, that warranty only covers the transmission if it’s defective, not the labor costs that you’ll have to pay.

Solution B: Buy a Rebuilt Toyota Sequoia Transmission

Another option would be a rebuilt transmission or rebuilt transmission. A local repair shop will remove your transmission, then install a bunch of new parts during the rebuild. The problem here is, the skills and experience of each transmission rebuilder will vary widely from shop to shop, so you could have problems from something that wasn’t adjusted properly. And the 1-2 year warranty might only cover you at certain transmission repair shops, in a specific geographical area.

Solution C: Buy a Remanufactured Toyota Sequoia Transmission

Many owners depend on their vehicle to commute and get things done. Their gasoline engines are designed to go 100’s of thousands of miles, so it makes sense to invest in a remanufactured transmission.

Went to shift it into reverse tonight and it wouldn’t go, made a weird noise…like a grinding sound. No check engine lights have been on, no strange noises or smells, etc. It is a 2001. It has 177k miles on it.

I have an opportunity to purchase 2003 Toyota sequia213,000 would this be a good buy

Last year I purchased a 2005 Toyota Sequoia which now has over 171,000 miles. I recently noticed that the transmission is slow to change into second gear when I first drive out of the garage in the morning. I see no other signs of issues. Is this normal? I wanted to check the transmission fluid but can’t find it.

It’s a “sealed system” so there’s no dipstick. U gotta lift the car and unbolt the transmission pan to know how much fluid is in there. U should change the tranny fluid but be careful only go to a good mechanic for this job!

Did you end up resolving this? My 2001 Sequoia has similar symptoms.

Unbolt the Drain plug. Drain the transmission pan. Measure the amount the came out. Usually around 3- 3.5 quarts should be a good amount. Put the same amount back in. Or fill it up through the top fill plug until it come out of the check level plug on the bottom.
