It replaces OE 8667689 and similar part numbers with a durable metal mesh pickup that resists clogging better than felt or plastic filters, and it includes the pan gasket and intake seal required for a complete service. Use this when performing routine maintenance or when diagnosing shifting problems on classic GM RWD cars and trucks from the 1982–1993 era.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the all-metal screen improve performance in a TV-cable transmission?\u003c\/h3\u003e\n\u003cp\u003eMetal mesh provides higher sustained fluid flow versus felt\/fiber elements, which can capture fine debris and restrict passages. For transmissions that rely on throttle valve (TV) cable control, consistent line pressure is essential; the metal screen helps maintain that pressure and avoids flow-induced shifting faults.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eHigher open-area flow than felt filters\u003c\/li\u003e\n  \u003cli\u003eLess prone to trapping fine particles that alter hydraulic response\u003c\/li\u003e\n  \u003cli\u003eStable performance under repeated heat cycles\u003c\/li\u003e\n  \u003cli\u003eDesigned for transmissions using TV cable rather than electronic control\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill this filter fit my vehicle and how do I identify a shallow pan?\u003c\/h3\u003e\n\u003cp\u003eThis Ortopia kit fits TH700-R4 (700R4) and early 4L60 models that have a shallow, flat-bottom pan—commonly found on many GM RWD cars and light trucks from 1982–1993.
