Allison at545 transmission parts breakdown

We waited three months and nearly finished our conversion and just pulled the trigger and started this project, a local shop (and friend) let us pull in and begin. The guy bought a used 1992 International bus because he needed the motor in his harvester, and no doubt parted the rest of the bus out and got all of his money back, we paid $400 for this, which also had the torque converter, flex plate and flywheel, and a broken dipstick. I immediately set out to find a MT643 and I did, in Oklahoma. So I bought the bus with the wrong transmission, but hey, it was a 15 window MT643, right after we picked it up.Д¤0 footer with tons of basement storage, low miles, all mechanical motor thatвЂ™s easy to tweak. Other benefits of the MT643 is its ability to handle more horsepower and torque from the motor and its Gross Vehicle Weight Rating(GVWR) of 70,000 Lbs versus the AT545вЂ™s GVWR of 30,000 Lbs. because of this, there is less slip, less heat, lower RPMs per MPH and more power transferred to the drive tires. The MT643 will lock the converter after accelerating through third gear directly connecting your driveline to the motor.

In essence, it always has some slip like riding the clutch in a standard transmission. All Automatic transmissions have torque converters but the AT545 does not have the ability to LOCK. (see this ultra boring video about how it works How Torque Converters work). It works with a set of impellers and transmission fluid flowing between them to transfer power from the motor into the transmission. What is a torque converter? and locking? (IвЂ™ll be short about this) The torque converter is basically a fluid clutch between your motor and transmission. ItвЂ™s a great transmission if you plan to actually perform school bus duties and or other in town stop and go duties. ItвЂ™s a good transmission for several reasons, First, not having a Lockup torque converter gives it smoother shifts, and the ability to convert torque with the slipping converter does help you get the ball rolling. With the Allison AT545 you donвЂ™t get all that power directly transferred to the wheels.

WHY? вЂ“ Simple, if youвЂ™re a daily diesel driver then youвЂ™re familiar with hearing the turbo spool and the torque of the motor begin to pull you ahead, no matter what speed (unless you drive a dodge). So I decided (mainly because we donвЂ™t focus on taking pictures while doing projects) that IвЂ™ll do a small write-up on installing an Allison MT643 in place of the Allison AT545
