Transmission Shims
WARNING: This page is about a different car, the 2003 GMC Safari and 2003 Chevrolet Astro. However, it is still accessible from the selected car via links, so may be relevant.
If a transmission requires shims, order the shims through the parts distribution system.
Installing most shims will change the transmission angle approximately 1/2 degree.
When shimming transmissions, use a shim made from steel stock at the necessary thickness. Ensure that the shim contacts the full width of the area to be shimmed. Do not use washers.
