This U151E, U150E, U151F, U150F are one of the most popular torque converter automatic gearbox in Toyota cars
Infact, in Nigeria today, Toyota 10, 13, 22 and 21 Pin Gearbox are the most popular
You need not argue with me on this, consider the number of people using either a Toyota Camry, RAV4, Highlander, Lexus ES300, ES330, RX330, RX300 etc in your LGA, how much more in Nigeria at large
Yes, Lexus ES300, ES330, RX300, RX330, RX350 old body, Toyota Highlander with 3MZ Engine and upto 2013 with 2GR Engine, Toyota Sienna with 3MZ and 2007 2GR engine, Toyota RAV4 with 2AZ engine,etc Toyota Camry with 1MZ, 2AZ, 2GR etc all have 13 PIN Gearbox
This 13 PIN Gearbox is a 5 Speed traditional Automatic Transmission that features the P,R,N,D,4,3,2,L shift positions
The torque converter in this gearbox is responsible for transferring power from the engine to the transmission and helps to keep the engine running when the car is stopped
Toyota 13 PIN Gearbox is reliable but develops issues after 150-200K miles due to wear and Tear, weak valve body, bad driving habit and inappropriate maintenance
As recommended, Toyota T IV is the recommended gear oil, sadly car users service their gearbox with cheap, fake and unrecommended gear oils which ends up causing several issues to the gearbox
Hard shifting especially between 2 and 3 gears, also 3 and 4, gear Slipping, higher RPM on low gear caused by falling pressure control Solenoids and contaminated valve body due to poor maintenance are the issues with 13 PIN
It is very difficult and expensive to fix this gearbox, reason is because of the cost of the tranny kits which are mostly inferior parts, lack of technical know-how and complexity of the valve body
I sincerely recommend that you replace your 13 PIN Gearbox once it develops issues because there have been reported cases of the gearbox failing after few months plus the maintenance cost is almost enough to get another one
DTC Codes like P0700, P0775, P0776, P0777, P0500 P0778 etc are few of the DTC codes you would see after diagnosis
If your car uses 13 PIN Gearbox, do well to properly maintain the gearbox with original recommended gear oil, and pay attention to the ABS warning lights on your dashboard
The 13 PIN Gearbox relies heavily on the data from the ABS wheel speed sensors and vehicle speed sensor for smooth gear shifting, so do well to fix the ABS warning lights
13 PIN Gearbox price range is between 450-550K depending on your car’s drivetrain
As you’re buying a Toyota or Lexus with the above mentioned transmission system, do well to note that the gears do fail too
