Product Overview:

Covered by a Limited Lifetime Warranty

More fluid means better thermal stability. PPE’s Heavy-Duty DEEP Allison Transmission Pan holds an extra 4 quarts and is cast from high-strength aluminum for optimal heat dissipation.

Internal 1" and external 3/4" cooling fins reduce operating temperatures by up to 40°F.

Includes a Neodymium magnet-equipped drain plug to trap harmful ferrous metal contaminants.

PPE’s built-in filter lock keeps deep filters securely in place. Allen-head mounting bolts and a new deep filter are included.

Features:

• External cooling fins measure 6.25" from gasket face
• Internal heat sinks reduce oil temps
• 4 quart additional oil capacity
• Decreases transmission temps by up to 40°F
• Robust side ribs for added strength

PPE Double-Deep Spin-On Filter:

Standard spin-on filters fall short. PPE’s Double-Deep Filter offers 2.72x more filter media surface area, trapping particles down to 15 microns—half the size of standard filters. This ensures cleaner oil flow and smoother, more responsive shifts.
