Toyota Tacoma Transmissions: Overview, Problems, Fluids

The Toyota Tacoma is one of the popular mid-sized pickup trucks available around the world. Toyota launched its first generation in 1995, designed to step up on vehicle handling, safety, comfort, and ride quality. In 2004, Toyota rolled out its more spacious and more powerful version in its second generation. It involved three different cab sizes, four transmissions, two engines, and a set of two varying bed lengths. The latest generation of the Toyota Tacoma that has redesigned exterior came out in 2015. Along these lines, we will discuss today in detail regarding different transmission used throughout its three generations. So, let’s get started.

Toyota has used 4-speed automatic and 5-speed manual transmission in the first generation of the Toyota Tacoma. Meanwhile, it has incorporated 4- and 5-speed automatic and 5- and 6-speed manual transmissions in its second generation. Finally, it put 6-speed automatic and 5- and 6-speed manual transmissions in its latest generation.

We acknowledge that the above explanation provides a compact overview. By all means, it is not enough to understand transmissions that went inside the Toyota Tacoma. Therefore, we will discuss transmissions with different dimensions to understand various models that go inside it throughout its journey. We will additionally take a look at the cost of replacement and their durability. In addition, we will see some common problems that surface during the lifetime of those transmissions. Eventually, we will see some differences between those transmissions. So, here we begin.

What Transmissions Has The Toyota Tacoma Used?

Here we see different transmissions the Toyota Tacoma has used throughout its journey.

First Generation (1995–2004)

  • 4-speed A340E automatic
  • 5-speed manual

Second Generation (2004–2015)

  • 4-speed automatic
  • 5-speed A750E automatic
  • 5-speed manual
  • 6-speed manual

Third Generation (2015–Present)

  • 5-speed manual
  • 6-speed AC60F automatic
  • 6-speed manual (RC62F)

How Long Does A Toyota Tacoma Transmission Last?

The durability of the transmission is contingent on the kind of it. Moreover, regular maintenance also plays a significant part in determining its proper functioning. When it comes to the transmission of the Toyota Tacoma, it usually lasts between 100,000 and 120,000 miles. To increase the lifetime and smooth running of it, experts recommend fixing problems at once. Besides that, it is also essential to keep the fluid levels topped up.

How Much Does A Toyota Tacoma Transmission Cost?

Has your transmission got dysfunctional, and are you looking to get it replaced? In that case, it is significantly vital to know the prices of different transmissions that the Toyota Tacoma embraces. For your help, we offer you an overview of the costs of several transmissions down below.

  • 4-speed A340E automatic: $3,499.00 (Pnductionperformance)
  • 5-speed A750E automatic: $2,395.00 (SPPrecision)
  • 6-speed AC60F automatic: $1,399.99 (eBay)
  • 6-speed RC62F manual: $ 3,840.10 (

Common Toyota Tacoma Transmission Problems

Now, let us see some common problems of transmissions that go inside the Toyota Tacoma.


  • The most common problems you can experience with the A340E transmission are erratic shifting, failure of gear engagement, or loss of the forward gears. The reasons behind such happening are an issue with the torque converter or a failed solenoid.
  • Overheating is another issue with the transmission. It occurs most often when the running parts inside the A340E create more friction heat than the automatic transmission fluid can eliminate. Driving in stop-and-go traffic, towing heavy loads, or riding on mountainous roads often cause overheating.
  • Inoperable reverse or fourth gear can also take place with the transmission. It is the consequence of the design flaws in the channel plate, reverse boost valve, and stripped splines on the fourth gear clutch hub shaft.


  • Aggressive driving style and enduring overheating can lead to several problems with the valve body, torque converter, and solenoids. It may happen after between 70 and 80 thousand kilometers. However, it is essential to note that it occurs when driving either on snow or off-road territory.
  • Solenoids should replace all the friction components when one fails to overhaul the A750E transmission for a long time.
  • Vibrations and fluid leaks via the pump seal can occur because of the transmission operations with a tattered torque converter clutch.
  • One has to select the solenoids and valve body of the A750E to replace for every car complying with its VIN-code (vehicle identification number). It is because the valve body of the A750E transmission got constantly modified.


  • There are complaints regarding the too soon upshifting and gear hunting.
  • Complete disc failure and severe clutch burn are additional problems with the transmission. The issue is usually linked to repeat and loaded use in reverse, although determining the exact cause requires more information.
  • It is good to find out information about the operating conditions and vehicle load, provided that you confront such failure.


  • There are complaints regarding the 6-speed manual transmission of the Toyota Tacoma. For one thing, a driver may experience difficulty when shifting out of fifth or sixth gear. The problem usually emerges when a driver drives for an extended time.
  • You can fix the issue by getting to the main lock ball plug by drawing out the transmission. Subsequently, you can replace it with a new lock ball pin.
  • Moreover, a driver may feel rough gear shifting from first to second gear. Besides that, too early transmission shifting and slipping are two additional issues with the transmission. A driver may also experience delayed engagement when shifting from reverse to drive or park to drive.

Differences Between Transmissions

The A340E is a 4-speed automatic transmission. For context, it is not a limited purpose single transmission. Instead, it is a class of closely related products from similar components, albeit not completely interchangeable. There are different bell housing bolt patterns, different output & input shaft types, provisions for a front-wheel-drive transfer case, different sump capacities, different valve bodies, and other vital variants.

The A750E is a 5-speed automatic transmission for rear-wheel-drive vehicles. It is one of the transmissions that seek power performance and fuel economy improvement. To achieve the purpose, it has gained compactness and top-level weight while keeping up high torque capacity. Its manufacturer has also embraced advanced technology, while the torque converter, gear train, and other components are entirely changed. At the same time, it has obtained quiet performance and a superior-quality shift feel.

The AC60F is a 6-speed automatic transmission, and its gearing is designed to optimize performance. It has an increased start-off drive power since it has a shorter ratio for the first gear. A longer third gear precedes a direct-drive fourth gear. Furthermore, five and sixth overdrive gears provide additional fuel economy performance. Deceleration downshift control, high-speed gear effective utilization control, and AI shift control are also part of the transmission. For the record, deceleration downshift control helps a driver reduce engine speed when the car slows down.

The RC62F is a 6-speed manual transmission, and it leverages an output reduction method to obtain a compact construction. It uses a multi-cone synchromesh mechanism to improve the shift feel for the first, second, and third gear. For the fifth and sixth gears, it utilizes double overdrive.

Transmission Fluids And The Toyota Tacoma

It is good to change transmission fluid every 45,000 miles, according to car manufacturers. But, one should keep in mind that different transmissions need different types of transmission fluid. Here we give you the source of the transmission fluids that will help you find the one that works with your transmission.
