Buying Guide

Match kit to transmission model

Confirm the kit lists your transmission code (6L80/6L90, 68RFE, 8HP70) or vehicle application—proper fit prevents leaks and valve body interference

Check included components

Look for kits that include both filter and full gasket/seal components so you replace all wear items during service

Material and filter design

Prefer kits with durable metal or reinforced plastic filter housings and multi-layer media for reliable debris capture in high-mileage units

Compatibility with fluid type

Ensure the kit is intended for your transmission fluid spec (automatic fluid families used by GM, Ram, or FCA 8-speed) to avoid seal swelling or degradation

Value vs. application complexity

Budget kits suit routine pan/filter services, while higher-cost kits that include extended hardware or OEM-style gaskets can simplify labor on heavy-duty or 8-speed services
