Th400 Chrm Deep Trans Pa

The TRANS-DAPT TH400 Chrome Deep Transmission Pan is a purpose-built upgrade for TH400 transmission systems that increases fluid capacity while improving heat dissipation through ribbed steel construction. This chrome-finished pan adds 1.5 quarts of additional transmission fluid capacity, a critical upgrade for high-performance builds, towing applications, and street machines where thermal management directly affects transmission longevity and shift quality.

The 3-inch deep pan design maintains proper fluid level while the ribbed steel structure increases surface area for cooling—essential when your TH400 sees sustained load or elevated operating temperatures. TRANS-DAPT engineered this pan to work seamlessly with stock TH400 mounting points without modification. The bright chrome finish provides both aesthetic appeal and corrosion resistance, though inspections during oil changes remain necessary to monitor fluid condition and catch potential wear debris early.

This upgrade addresses a common limitation in street and strip TH400 applications where standard pans often prove inadequate under sustained power delivery or extended towing duty. The extra capacity buffers against thermal stress and maintains fluid film strength longer between services. Weighing 4.3 lbs and measuring 14.6 x 3.8 x 18 inches, it fits standard engine bay layouts. Buyers should verify clearance with their specific installation before ordering, particularly in tight underbody configurations.

The TH400 remains the gold standard for built engines and street performance applications, and fluid capacity becomes increasingly important as horsepower climbs. This pan upgrade is commonly paired with transmission coolers and premium synthetic fluids to create a thermal management system capable of handling modern power levels reliably.
