Scribner Automatic Transmission Case

Scribner Plastics Automatic Transmission Cases: Race-Proven Protection

When a transmission represents thousands of dollars in parts and labor, how you store and transport it matters just as much as what's inside. Scribner Plastics has built its reputation over decades by solving exactly this problem — delivering rugged, purpose-built automatic transmission cases trusted by professional racing teams across NASCAR, NHRA, IndyCar, and SCCA.

Established in 1978, Scribner Plastics pioneered the concept of reusable, high-strength plastic containers for motorsports applications. Their automatic transmission cases are a direct extension of that legacy: containers engineered for the demands of racing shops and core return cycles, not lightweight single-use packaging.

What Sets Scribner Automatic Transmission Cases Apart

At the heart of every Scribner automatic transmission case is heavy-duty rotationally molded polyethylene — the same process used for their entire professional container lineup. This construction method produces walls with exceptional uniformity and impact resistance, and the material itself is completely impervious to transmission fluid, gear oil, and common cleaning solvents. You can wipe down, clean, and reuse these cases through many core return cycles without degradation.

• Fluid-resistant polyethylene construction — unaffected by transmission fluid, gear oil, or cleaning solvents
• Stackable interlocking design — saves floor space in the shop or trailer when cases are stacked
• Multiple size options — including a medium 24 x 24 x 32 in. case (part #5122) for shorter automatics and a large 24 x 27 x 46 in. case (part #5127) for long-tail units
• Pan inserts with cinch straps — the larger case includes a 25-PAN insert to secure the transmission within the container during transport
• Tapered nesting profile — empty cases nest together for compact storage
• Broad fitment coverage — the medium case accepts GM Powerglide, TH-350, TH-400, 700R-4, Ford C-4, AOD, AODE, and Chrysler TF-904, while the large case handles GM TH-400 with 12" long tail, 4L80E, Ford C-6, and Chrysler TF-727

From the Track to the Shop

Scribner's automatic transmission cases aren't just for racers — they make equally good sense for rebuild shops, parts warehouses, and serious enthusiasts who want to store a spare transmission safely for the long term. The stackable interlocking design makes it practical to keep multiple units organized in a trailer or shop corner without wasting valuable space, while the fluid-tight construction means a leaky transmission won't ruin anything stored nearby.

Scribner Plastics earned the Chrysler Honors Environmental Excellence Recognition (CHEER) award in 1998 specifically for the quality and reusability of their returnable containers — a distinction that underscores why these cases have become an industry standard rather than a niche product.
