3RD and REVERSE CHECK BALL SLEEVE KIT

BY SONNAX

Vehicles with '95-later GM 4L80-E and 4L85-E transmissions commonly exhibit wear in the 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 the checkball becomes compromised and results in loss of apply pressure to direct clutches. Consequences of this pressure loss are slipping or no 3rd and 4th Gears, burnt direct clutches and ratio codes. Installing Sonnax 3rd and Reverse checkball sleeve kit S34741RK restores the hydraulic integrity of this circuit to reestablish normal shift operation and performance. Replaces worn checkball sleeve to correct loss of apply pressure; Components manufactured from high-strength, wear-resistant aluminum for added durability; Drop-in Zip Valve™ parts install quickly and easily
