Toyota Tundra Transmission Recalls
Toyota Tundra Technical Service Bulletins (TSB)
TSB 0170-09 – AB60 transmission C1 clutch damage
2007 – 2009 Toyota Tundra – 2008 – 2009 Toyota Sequoia
Problem – Drivers may experience transmission slipping or harsh shifting, with one or more of the following DTC’s; P2714, P0751, P0756, P0761, P0766, P0729, P0781, P0894, P2757, P0776.
Solution – The C1 clutch assembly may need to be replaced, and the ECU will need to be reprogrammed with the latest software version.
TSB 0277-09 – Check engine light illuminated with DTC P0705 – AB60E transmission
2005 – 2009 Toyota Tacoma
Problem – Some owners may notice a check engine light illuminated the gauge cluster, along with symptoms such as delayed engagement of reverse or drive. Engaging park or neutral may also be usually harsh. A P0705 diagnostic trouble code may be stored in the ECU.
Solution – This issue may be caused by corrosion in the engine room main wiring harness and junction block no. 1. To fix the problem, the wiring harness will have to be replaced (Toyota quotes a labor time of 4.5 hours, FYI).
TSB 0078-08 – Check engine light illuminated with a number of transmission performance DTC’s – AB60 transmission
2008 Toyota Tundra
Problem – Drivers may experience erratic shifting behavior, along with a number of diagnostic trouble codes that include: P0751, P0756, P0761, P0766, P0729, P0781, P0894, P2757, P0776.
Solution – A new/remanufactured AB60 transmission will need to be installed.
TSB TC018-07 – Torque converter shudder – AB60 transmission
2007 – 2008 Toyota Tundra
Problem – Drivers may experience an intermittent shoulder when they lightly accelerate after an upshift between 20 – 25 mph, or or for a downshift between 30 – 65 mph
Solution – In order to fix this problem, a revised AB60 torque converter may have to be installed.
TSB TC002-97 – P or N to Reverse engagement – A340E / A340F transmission
Toyota Tacoma – Toyota T100 – Toyota 4Runner – Toyota Land Cruiser
Problem – Drivers may experience a pronounced delay in the engagement of Reverse gear from the Park or Neutral position.
Solution – A revised B3 brake return Spring, B3 piston rings and low coast modulators spring will have to be installed.
TSB TC001-98 – Reverse to Park/Neutral chatter – A340E / A340F transmission
1997 – 1998 Toyota Tacoma – 1997 – 1998 Toyota 4Runner – 1997 – 1998 Toyota T100 – 1997 – 1998 Toyota Land Cruiser
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.

Can I drive with a transmission problem?
If your Toyota Tundra 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 Tundra transmission need to be replaced?
The overall lifespan of a Toyota Tundra 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 Tundra 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 Tundra transmission issues diagnosed?
It is fairly easy to guesstimate what the root cause of your Toyota Tundra 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 Tundra transmission replaced?
In order to replace your Toyota Tundra 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 Tundra Transmission Problems
Solution A: Buy a Used Toyota Tundra 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 Tundra 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 Tundra 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.
