Can a transmission be tightened?
Can a transmission be tightened?
The technicians at All-Automatic Transmissions understand that problems with your vehicle’s transmission can often be resolved with adjustments or a minor repair. In fact, a simple adjustment can be done without even removing the transmission from the vehicle.
Why do I need to tighten the bands on my transmission?
The technical answer goes like this: In some transmissions, part of the operating controls include “bands”: metal straps with friction material on one side. When applied, the bands tighten around drive components to hold them in place. To apply exactly right, those bands needed to be adjusted properly.
How is a steel band applied to a transmission?
The spring-like nature of the steel band helps keep the end gap at its widest until the band is applied. Like most physical movements in an automatic transmission, the band is applied by hydraulic pressure. Valves in the transmission govern the timing of fluid pressure on a piston, or servo.
How does a servo push rod adjust the band?
The other end of the band is held stationary by a fixed rod, and this device, or the servo push rod, is the adjustment point. Typically, the threaded rod passes through the transmission case to allow external adjustment of the band end gap. A band that is adjusted too tightly will displace the fluid that prevents friction material loss.
Where can I get help with my transmission?
Your nearby Cottman center’s technicians are well versed in diagnosing today’s transmissions and will work with you to take care of them. And, when you bring your car to your local Cottman center, you can be sure you’ll never pay for a transmission unless you really need a transmission.
What does tightening the bands in a transmission do?
Typically, the threaded rod passes through the transmission case to allow external adjustment of the band end gap. A band that is adjusted too tightly will displace the fluid that prevents friction material loss.
When is it too late for transmission band adjustment?
Even in those older cars, transmission band adjustment was maintenance — something you did before a problem showed up. Once the transmission started acting up, it was generally too late.
