Abstract
An apparatus and method for repairing hydraulic fluid leakage from the low/reverse gear fluid circuit of an automatic transmission case is disclosed. The present repair kit comprises a deformable grommet seal used in combination with a steel shim to replace the original equipment gasket, which is the source of the fluid leakage. Installation of the steel shim compresses the grommet seal in the fluid passage thereby creating a leakproof seal and maintaining the integrity of the low/reverse piston fluid circuit. In addition, the steel shim functions as a spacer in replacement of the original equipment manufacture gasket, which is discarded, and also provides a non-compressible backing surface to prevent distortion of the piston retainer when it is assembled and fastened against the shim.
