Depends what car the 1JZ came out of. If it was a MK3 supra, no. If it was a Soarer or chaser, yes.
If all else fails, spend the $350 for the latent solutions stand alone transmission ECU. I run one on my car. Still working out the bugs and getting it tuned, but its a very good unit. Fully programable shift tables, or u can goto "manual" mode and paddle shift with whatever u want to hook up to it (i use my cruise control joystick)
If your really cheap, u can just control the shifting with 3 toggle switches from discount auto parts
