Can I drive with a transmission problem?

If your Toyota 4Runner 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 4Runner transmission need to be replaced?

The overall lifespan of a Toyota 4Runner 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 4Runner 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 4Runner transmission issues diagnosed?

It is fairly easy to guesstimate what the root cause of your Toyota 4Runner 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 4Runner transmission replaced?

In order to replace your Toyota 4Runner 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 4Runner Transmission Problems

Solution A: Buy a Used Toyota 4Runner 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 4Runner 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 4Runner 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.

at D around 40 to 60 km/hr speed feels like the car hits a gravel just for s spit seconds, and accelerates. By pass D to 3rd no noise and engaged back to D no problem noise

I have a 14’ 4Runner Limited with 155,000 miles it is sluggish going up hills and has a terrible whining sound when accelerating! Not sure if transmission related! No codes detected!

It makes me wonder if a catalytic converter is plugging up. If driven fast for a while at night, like the freeway, perhaps pull over quickly to see if it is apparent if one of them is glowing red hot.
