Description

Vehicles with GM 4L80E and 4L85E transmissions commonly exhibit wear in the 3rd and Reverse checkball sleeve located in the 3-4 shift valve bore. This issue is caused by normal movement of the checkball within the sleeve over time. As wear progresses, sealing function of checkball becomes compromised and results in loss of apply pressure to direct clutches. Consequences of this pressure loss are slipping or no 3rd, 4th, and Reverse gears, burnt direct clutches, and ratio codes. Installing Sonnax 3rd and Reverse checkball sleeve 34200-38 restores the hydraulic integrity of this circuit to reestablish normal shift operation and performance. Package Quantity: 4
