Remanufactured Toyota 4Runner Transmissions 

 

Ever since it was first introduced, the Toyota 4Runner has been one of the most desirable off railroad SUVs on the market. However, transmission problems with the A340F, A340E, A750E or A750F aren’t very desirable at all. So let’s find out if installing a remanufactured Toyota four Runner transmission can restore your little rig’s reliability. 

 

Common Toyota 4Runner Transmission Problems  

 

Reverse to Park/Neutral chatter – A340E / A340F transmission  

Problem – Some vehicles may experience a chatter noise when shifted out of Reverse into either Park or Neutral. 

Solution  A revised A340 valve body design has been created with an additional check ball to prevent this problem. 

 

Erratic Shifting / Loss of Forward Gears: If you’re experiencing A340E, A340F, A750E or A750F transmission problems like slipping, erratic shifting, or failed gear engagement, the causes could range from a failed solenoid to a torque convertor issue. 

Another common problem is overheating. This happens when the moving parts inside the transmission are creating more friction heat than the ATF can remove. The most common cause of this condition is towing heavy loads, driving in stop/go traffic, or on mountain roads where the transmission has to shift a lot. 

Loss of 4th Gear and/or Reverse: Another common problem is an inoperable fourth or reverse gear. These issues are often caused by design flaws in the Reverse Boost Valve, channel plate, and stripped splines on the 4th gear clutch hub shaft. 

 

How to Solve Toyota 4Runner Transmission Problems 

 

Solution A: Buy a Used Toyota 4Runner Transmission  

Going to the local junkyard and picking up a used Toyota 4Runner transmission might seem like the cheapest and fastest option. But you need to consider the fact that you don’t know what the actual shape of the internal components are. It could very well be on the verge of transmission problems of its own, which would leave you in the exact same predicament that you’re in now. And that 30 – 90 day junkyard warranty probably won’t cover labor charges to install the replacement transmission if something goes wrong. 

 

Solution B: Buy a Rebuilt Toyota 4Runner Transmission  

Getting a rebuilt Toyota 4Runner transmission would probably seem like a better idea. However, a lot of mechanics and transmission shops will only rebuild your Toyota 4Runner transmission back to its original factory specifications. Which means that all of those factory design flaws are still going to be in-play. And that rebuilt transmission warranty might only be good at certain shops, which could do you no good if you have transmission problems while you’re traveling. 

 

Solution C: Buy a Remanufactured Toyota 4Runner Transmission  

If you want to get the most service life out of your vehicle as possible, then you really should consider a remanufactured Toyota 4Runner transmission from Street Smart Transmission. Each one is completely disassembled and re-remanufactured, so nothing is left to chance. They’re also modified to correct the factory design flaws, which will greatly extend the service life. Plus, you get a 3-Year/Unlimited Mile Nationwide Warranty. This will cover parts and labor charges at any licensed repair shop in the Continental United States, giving you a lot more flexibility and coverage.
