The 1.218" counterbore on T2-3-12051HP is the TH700/700R4 identification feature -- the same counterbore found on 3-3-4281X and T3-3-4281HP in the 1350 series. This yoke is the 1330 series equivalent for 700R4 builds where the intermediate torque capacity of 1330 is appropriate. As noted throughout this product family, the 700R4/4L60 counterbore is the critical distinguishing dimension from the TH350 no-counterbore yokes at the same spline count.

Forged chromoly construction handles the overdrive shock loads that the 700R4 generates at the 3-4 and 4-3 shifts in performance applications. Replace the 700R4 output seal at each yoke removal -- a known wear item on high-mileage 700R4 transmissions. Confirm the specific 700R4 build year as the retainer OD may vary slightly between early (1982-1987) and later (1988+) production units.
