Overview

The COA-91100A is a rugged, race-ready version of the Turbo Hydramatic 700-R4 automatic transmission, purpose-built for serious street and bracket competition. Engineered to withstand high loads and aggressive driving, it features robust five-pinion planetary gearsets, a heavy-duty sunshell, billet servo, and a super input drum to handle repeated abuse without failure. The inclusion of a billet forward piston and high-performance band improves hydraulic apply control, while the “Z-PACK” 3–4 clutch assembly delivers enhanced holding capacity and smoother engagement during demanding shifts. Fully assembled in the USA to Coan Racing’s stringent performance standards, the COA‑91100A is an ideal turnkey solution for enthusiasts seeking both durability and no-compromise performance in a compact automatic package.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
