Turbo TH400 Transmission Teardown / Disassembly! Satisfying - 1990 C2500 GMC/Chevy

Welcome to Inside the Case, where we take a deep dive into the inner workings of real transmissions, transfer cases, and differentials! In today’s teardown, we dive deep into the TH400 (TURBO 400) TRANSMISSION from a 1990 C2500 3/4 GMC AUTO RWD P/U TRUCK. This is one of the most popular light-duty manual transmissions used in GM trucks throughout the 1980s and early 90s — and today we’re breaking it down piece by piece.
