Looking at today’s digital age, it’s not uncommon to hear someone say conversation has become a lost art, just like cursive and tv repair. What we think they should be talking about, is the lost art of rebuilding a transmission. And it IS an art.
When you look at the average transmission has over 600 different parts, all with a specific design and purpose, anyone who opens a transmission to rebuild it has their work cut out for them. We have several rebuilders on our staff with over 80 years of combined experience who take on that challenge every day. All they do is rebuild transmissions and they love what they do.
What is a Remanufactured Transmission?
You might wonder what the difference is between a rebuilt and a remanufactured (reman) transmission. Honestly, there isn’t a whole lot of difference between a quality reman and a rebuild. One is done in a factory setting, assembly line style, where different people specialize in various parts of the repair process. The other is done by one person in a transmission shop.
Because we have multiple rebuilders, our team can provide expert attention and diverse experience to your repair/ rebuild. A custom rebuild can also be completed quicker because the only delay is finding parts –. In most cases, an in-house customer rebuild can take between 2-4 days.
There might be some differences in warranty as well. Our advice to customers is to focus on the quality of the warranty provider because we hear horror stories of 5 year or unlimited mileage warranties from remanufacturers that either don’t honor the warranty when an issue comes up or simply goes out of business. At Power automotive Inc, we offer a two year 24k warranty and our warranty covers both parts and labor costs associated with any claim. With Power automotive you can be confident your transmission is in good hands.
100+ Types of Transmissions
Imagine the skill and time it takes to learn how to replace each and every one of the 600 plus different parts in exactly the right place. Then, consider learning each of the 300+ different transmissions, each being just a little bit different from the others.
Not only are transmissions complex, there are also over 300 different transmissions today, compared with only 10-15 different types years ago! This has made it incredibly challenging for those who rebuild transmissions in today’s environment; this is leading to rebuilding transmissions becoming a lost art.
It is also the reason many transmission repair shops have changed to total automotive care as we do here at Power Automotive Inc.
It is hard for any individual to be an expert at that many different models/types of transmissions. Coupled with increasing electronic/programming sophistications (aka annoyances), repairing modern transmissions can be a nightmare.
Parts of a Transmission
For a transmission to work at peak performance, all parts need to be in top condition, carefully installed, and working in harmony. There are several major components in the transmission and within those are countless parts all doing their specific job. They are intricately designed to rely on each other. Here’s a basic rundown on the different functions and how they work together.
Pump: The pump pulls in transmission fluid and pressurizes it for the torque converter and transmission. The transmission cannot function without it, much like the heart does for the human body.
Planetary gear set: The planetary gear set is comprised of a sun gear, planet gears, and a ring gear. Arguably the most important part of every vehicle, this grouping is responsible for creating the gear ratios that make movement of the vehicle possible. How the planet gears lock or unlock as they revolve around the sun gear determines the gear ratio. This creates rotational force that is sent to the wheels through the output shaft.
Torque converter: Connecting the transmission to the engine, the torque converter is made of a stator, impellor and turbine. This component allows the car to stay in gear while sitting as well as making it possible for the car to accelerate after stopping.
Clutches and bands: Pressurized fluid causes the pistons inside the clutches to engage and the bands tighten or loosen around gears. These functions aid in shifting gears, by helping them to rotate and engage or disengage.
Sensors: Thought of as the control unit, they determine which gear is engaged by calculating the engine and wheel speeds. There are both input and output sensors.
Valve body: This uses hydraulics (transmission fluid) to control valves. These, in turn, send fluid to clutches and bands determining gear ratio. The pressure of the fluid (hydraulic action) will change based on the engine’s speed.
Transmission fluid: The lifeblood of the entire system, transmission fluid is not only used in a hydraulic capacity, it also cools and lubricates parts, helping to keep wear to a minimum. It is made of liquids, oils, rust inhibitors, lubricants and detergents and is traditionally bright red in appearance. Like all fluids, it expands and contracts with changing temperatures, therefore it is not surprising drivers in Colorado observe slightly difference shift patterns depending on external ambient temperature.
