GM 700R4/4L60E Trans Pan Chrome Steel Finned

The GM 700R4/4L60E Trans Pan Chrome Steel Finned is a direct replacement transmission pan engineered for Chevrolet's legendary three-speed and four-speed automatic transmissions. Whether you're running a classic Camaro, Corvette, or modern LS-swapped project, this chrome steel finned pan combines factory-correct fitment with enhanced cooling capacity and show-quality aesthetics. The ribbed design increases surface area for superior heat dissipation during sustained driving, towing, or spirited track use.

Manufactured by Racing Power Co-Packaged using heavy-gauge steel construction, this pan features full-coverage chrome plating that resists corrosion and maintains a show-car finish under the vehicle. The finned geometry—characteristic of performance and custom transmissions—dramatically improves heat rejection by expanding the cooling surface that contacts the transmission fluid. This is critical in high-performance applications where stock cooling alone cannot manage elevated fluid temperatures; reduced heat means tighter tolerances, longer fluid life, and improved shift quality. The stock sump capacity maintains OEM fluid volume, ensuring proper pan depth and pickup tube clearance without modification.

This pan suits restorers, street rodders, and performance builders who demand both function and visual impact. Installation is straightforward—drain the transmission, unbolt the original pan, and bolt on the replacement using the existing mounting holes and gasket surface. The chrome steel finned design is particularly popular in restomod projects where underbody detailing matters, and in forced-induction or high-torque builds where transmission cooling becomes a limiting factor. Compatible with 700R4 and 4L60E transmissions across full model year ranges, this 4.54 lb pan represents an economical upgrade that pays dividends in reliability and appearance.
