I am on the tail end of doing this swap using that same tech page you are refering to. I finally was able to drive it for the first time two days ago. Some background info first; my truck is an '87 xtra cab pickup with a 22re, the stock tranny/transfer is the a340h, 4" suspension lift 3" body lift, 5.29 gears front and rear.
As far as the info on the auto crawler page it is a fantastic write-up but it's dated, and missing some info. For instance, in my case I was using a doner tranny from a 1997 4runner with a v6. Same basic tranny but the bellhousing is different and so is the torque converter. I found out that it is still possible to do you only have to change the tranny input shaft so that you have the correct number of splines for the TC (I will try and get some pics up tomorrow).
He also says to change the solenoids which is not necessary unless the ones in the doner tranny are bad. They use the same solenoids.
well i was under the impression that the speed sensor in the extension housing was still needed for the tcm, but in that case screw it, my truck has a electric speed sensor in the tcase ill just re-use in the gear drive tcase.
Yes you do need it if you want the TCU/ECT to do the shifting. If you want to manually shift it then no you do not. The rear one is for the Speedometer/odometer only. The one in the extension housing on the driver's side with two wires/terminals is for the TCU/ECT. Ask me how I know...I said the same thing "screw it, I have two" but it doesn't work like that.
