Description
GM's Turbo-Hydramatic 350 (TH350/THM350) and Turbo-Hydramatic 400 (TH400/THM400) transmissions use a firewall-mount dipstick configuration, and this flexible braided stainless steel dipstick is built to fit both.
The TH350C's lock-up torque converter is an internal difference only — the transmission case and dipstick tube boss are identical to the standard TH350, so this dipstick fits both without modification.
It's commonly used in Camaro, Chevelle, Nova, and Corvette; C10/K10 and Silverado trucks; Pontiac Firebird and GTO; and other GM RWD platforms using the TH350 or TH400.
The dipstick measures 26-3/4 inches and uses a flexible braided stainless steel tube. Confirm tube length and mounting location match your specific installation before ordering. It is a fixed, non-locking design.
Featuring a black-finished aluminum handle, the dipstick adds a polished, show-quality appearance to the engine bay.
