Observations From the Field
Call ’em tech tips, building tips, details or whatever you like, but this is the stuff we see at events and shows while shooting features or doing shop tours, not to mention things we’ve discovered while working in our own shops. It’s like when you’re foot-cruising an event with the boys and pointing things out to each other, or when you have a stroke of genius while working on your own project.

BURIED TREASURE
Suddenly it was 2007! That may not be a big deal to a lot of people, but there were a lot of folks who were very excited that it was 2007. In fact, most of the population in Tulsa, Oklahoma, was openly excited that 50 years had passed since June 15, 1957.

Flare with Style
Arnold Hemedinger, a self-employed European auto mechanic and a die-hard Jeep lover, discovered an 88’ YJ Jeep Wrangler that had been stored in a barn and obviously seen better days. Arnie, being the visionary he is, instantly saw the jeep as a diamond in the rough and with a little tender care would polish out brilliantly. His wife on the other hand saw the jeep only as another mid-life crisis project that would sit among two and half acres of other would-be diamonds.

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)
