When to Replace a Transmission

In addition to transmission repairs and maintenance, you might also need to replace your transmission. How do you know whether repair or replacement is the cost-effective solution: 

  • If the clutches, front pump, and slave cylinder malfunction, repairing is less expensive. 
  • If the planetary gears and other hard parts in the transmission’s rear are gone, replacing the entire transmission is often less expensive.
  • If the valve body is damaged, replacing the transmission might be less expensive (depending on the transmission type). The valve body has a filter just below it. If the veins in the valve body are clogged and cannot be flushed or the valve suffers other damage, it might need a replacement.


Branch Automotive in Littleton, CO does both transmission repair and replacement. We’ll diagnose the problem and let you know the best action to take.

You can prevent the need to replace the transmission by making sure you perform the required maintenance, like transmission flushes and changing the transmission filter.

Transmission Maintenance in Littleton, CO

To keep your transmission in good working condition, keep up with its maintenance. Maintenance on a transmission includes exchanging the fluid, replacing the transmission filter, and cleaning the valve body in some cases.

As the clutches rub together when you shift gears, they create slivers of clutch material, including metal. The veins in the valve body are tiny—it doesn’t take much to clog them and prevent the transmission fluid from lubricating the system. Without lubrication, the internal parts could fail.
