TRANSMISSION, AUTOMATIC

Transmission case must be OEM or aftermarket OEM replica from a standard automotive application as found in the Official NHRA Stock Car Classification Guide...."

No special notes for trans in the GT section, so these rules apply.

"Make" means "Manufacturer" (Ford, GM) and "Model" means part ID (Glide, ect for GM, C4-C6 for Ford ect). Correct me if I have this wrong.

Does anyone use the OD feature on the 3 speed plus Overdrive transmissions?
