Review on 🚀 Enhance Performance and Stability with PROTHANE 7-1604 Red Urethane Transmission Mount Kit for 6 and 8 Cylinder Engines by Steve Arnold

Installed on my 91 Trans Am. 5.7 with 700R4 gearbox. Works perfectly, you may notice a little more engine/transmission noise as it is more durable than the stock rubber mount. Installs at the same time as installing the ES Poly Torque Lever. I deducted 1 star because I had to widen (widen) the slot in the gearbox a bit. The hairpin provided is too wide to fit through. Nothing can be solved in 10 seconds with a grinder or a dremel wheel.
