New-Age ‘Cuda
Upon approach, it stirs the heart much like the sight of an old friend, with the flowing contours that recall memories of great times and fast, simple cars—before we knew much about automotive computers, CDs or the true meaning of lateral acceleration and G-force. Like a favorite teddy bear from childhood, this welcomed image warms our hearts, yet beneath that familiar façade is a grizzly bear of sorts. One that will grab you by the throat, slam you against the seat back and rip heart-pounding sensations throughout your body. This is no ordinary ’70 Plymouth Barracuda—this is a rush!

’69 Camaro Update
The late ’60s was a good time for automobile enthusiasts everywhere. For Chevrolet specifically, it remains a time when the company produced vehicles that are among the favorites of Bow Tie aficionados. Who wouldn’t want a ’67-’69 Chevy Chevelle, Nova or, of course, the ever-popular Camaro? The design of these vehicles, and many others from that era, has stood the test of time, and car manufacturers today are even reverting back to the styling cues of these classics when designing modern production cars.

IN WITH THE GOOD AIR
When a B16A-equipped CRX EF came into the Rage Performance shop for a Skunk2 intake manifold install, the crew dove into the job with a fury. With cameras at hand to document the swap (’88-’91 CRX) for your personal pleasure, the job took no time at all and the owner of this Honda is deliriously happy with the results.

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)
