Who needs a jack, be a man and bench press your transmission.
This is my install of a w58 / R154 transmission on a 1986.5 7mge / 7mgte Toyota Supra. It’s been awhile since I’ve done it on the ground. Be sure to be more prepared than me with the right extensions. I always like to lose the motor mounts and then use a same 2x4 on the harmonic balancer and Jack up the front on the motor. This will allow easy alignment of the trans on to the doll pins. Be sure your clutch is fully installed as well as clutch fork. I’d recommend installing the two top bolts first as they are impossible to reach when the motor is flat.
This method works with 1jzgte and 2jzgte engines in 1986.5 - 1992 Toyota Supra
