The ZZPerformance 4T65E Master Overhaul Kit provides the essential components for a thorough transmission rebuild. The foundational kit contains all the gaskets, seals, and o-rings required to service your 4T65E transmission. Customers can customize the kit by selecting additional options from the "Model" dropdown menu. These options include adding friction pistons and steels, or choosing a "Gaskets Rings and Seals only" configuration. The kit also offers different year ranges for compatibility, with options for "1997-02" and "2003+". Note that the "97+ Variant" option is currently sold out or unavailable. This overhaul kit is designed for the 4T65E transmission, which is found in various GM vehicles.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
