1050 Transmission stud installer tool

Installing the bottom transmission case mount studs requires a tool that can handle the torque without damaging the threads. This Jims installer tool is designed for 1979 to 1986 4-speed Big Twins and works with both stock and aftermarket transmission cases. It allows you to drive the studs in straight and to the correct depth, ensuring a secure mount for the transmission. Using pliers or double-nutting can often lead to stripped threads or bent studs, but this tool provides a professional interface that protects your hardware. It is a simple but effective tool that belongs in every 4-speed builder's kit.
