The trans bushings are a part of the automatic transmission components that work to keep your Oldsmobile Achieva transmission operating smoothly. There are several locations and functions for these pieces, yet they all house input and output shafts. The size and type of transmission determine the appropriate size of the bushing you will need.
If you hear chattering or grinding noises coming the from under the hood, your Oldsmobile Achieva may be in need of transmission repair. Other noticeable signs include vibrations, whining, and shuddering. Replacing trans bushings will be necessary if you are rebuilding your transmission or if significant wear and tear is noticed.
