RB20DET Auto transmission Question?

[GIJOE69]

I have an automatic ka24e in my 89 240sx coupe and I was looking into dropping a RB20DET that has a Automatic Transmission is it true you don't need to replace the drive shaft ? and what else info or how to install or wiring setup for the rb20det

No, I have an automatic transmission rb20det and I needed get a single piece driveshaft made.

Also for wiring, there is no additional wiring for the automatic rb. Wire it up the same as the manual. I dont know how it worked but we followed the procedures for the 5 speed wiring and it works fine! Just make sure all the plugs that go to the rb auto transmission wiring harness goes to something...
