MERC-O-MATIC MAKEOVER
Gil Losi, the owner of this super-slick ’54 Mercury Monterey—which was a year in the making—has quite a liking for the ’54 Mercury body style. He’s owned several of the stylish Monterey hardtops, but this one tops them all with its slammed stance, laser-straight paint and bodywork and 32-valve DOHC engine. One of the many great aspects of this particular Mercury Monterey is that Steve Cook’s team started with a good body. It was solid and already featured a low-down stance, but the crew reworked every part of the car into what you see here.

What’s in the Box: Deep Cast Aluminum Transmission Pan, Gasket, Full Hardware Kit, Upgraded Late 5R110 Transmission Filter
The DIESELSITE Deep Transmission Oil Pan is a prime example of that mindset. After running several aftermarket pans on their own Legendary and Hercules transmissions, the folks at DIESELSITE wanted more—more strength, better filtration, smarter engineering—and they built exactly that.
Made from heavy-duty 356T6 cast aluminum, this pan isn’t just an upgrade—it’s an evolution. Built to protect your transmission under the toughest conditions, whether you’re hauling heavy or chasing horsepower.
Why It Matters
Unlike standard pans, this one features a reinforced, thickened flange that acts as a structural girdle. Translation: it helps prevent case twisting during high-torque abuse. Plus, with stud and flanged nut fasteners, installation is a breeze and rock-solid reliable. And because DIESELSITE knows these transmissions inside and out, they spec’d it with the late 5R110 transmission filter for maximum filtration.
Features You Actually Want:
- Increased Flange Thickness: Adds strength, prevents flex.
- Stud and Flanged Nut Fasteners: Better clamp load, easier install.
- Deep Sump: Adds about 5 extra quarts of fluid for better cooling.
- Upgraded 5R110 Filter: Cleaner fluid, longer life.
- Magnetic Drain Plug: Catches metal shavings before they become a problem.
- Temperature Sensor Port: Ready for gauges to keep tabs on temps.
The Real Benefits:
- Stronger Transmission Case: Reduces risk of catastrophic failure.
- Cooler Temps, Longer Life: More fluid = more thermal control.
- Cleaner, Protected Fluid: With filtration and magnetic drain.
- Ready to Monitor: Gage port built in.
- Smart Install: Studs provide full thread engagement for maximum clamping force.
- Filter Replacement Part Number: Ford 8C3Z-7A098-D (conveniently etched into the pan for reference)
