Sonnax 3-4 Relay O-Ringed End Plug Kits

Sonnax 3-4 relay O-ringed end plug kits help restore hydraulic integrity at the end plug of your transmission's valve body. In GM 4L60-E, 4L65-E and 4L70-E units, the hammering effect of the 3-4 relay and/or 3-4 shift valves can cause the end plugs to wear, resulting in loss of 4th signal and/or D3 oil. Replace the worn OE end plugs with a Sonnax 3-4 relay O-ringed end plug kit to prevent critical losses and provide a positive seal.
