Is your transmission leaking fluid around the dipstick tube? A worn or failed dipstick tube grommet is usually the culprit — and it's an easy, inexpensive fix.

Designed for universal fitment across the most popular GM automatic transmissions — including 4L60, 4L60E, 4L80E, TH350, TH700, and 700R4 — these seals work with a wide range of Chevrolet, GMC, Pontiac, and Buick vehicles. COMPATIBLE VEHICLES INCLUDE: Chevy Silverado (1500, 2500, 3500) with 4L60E or 4L80E GMC Sierra with 4L60E or 4L80E Chevrolet Tahoe, Suburban, Avalanche GMC Yukon, Yukon XL Chevy Camaro, Corvette (4L60E equipped) Chevy S10, Blazer, TrailBlazer Chevy Express / GMC Savana vans Pontiac Firebird, Trans Am (700R4 / 4L60E) WHY REPLACE YOUR DIPSTICK TUBE SEAL? Over time, the original rubber grommet hardens, cracks, or distorts due to heat cycling and constant ATF exposure. This allows transmission fluid to seep out around the dipstick tube — a leak that's often mistaken for a pan gasket failure. Left unchecked, low ATF levels cause overheating, slipping, and premature transmission failure. PRODUCT FEATURES: High-grade nitrile rubber (NBR) construction Resistant to ATF, heat, and ozone Precision dimensions for tight, leak-free fit Press-fit installation — no tools required Multi-piece pack for multiple repairs or spares Replace your leaking dipstick tube seal today and protect your transmission investment.
