Need reassurance on my thinking, manual to auto swap.

Ok so I bought me a p pump 24v for work and my 98 will be going under the knife for like the 10th time lol.



So I'm thinking about ditching my 6 speed and going the auto.



First off I want it to look factory swap out the colum dash and pedals.



I found a local wrecked 97 12v with an ats tranny. So my thinking is pull the tranny PCM , wiring harness and tps/ kick down cable. Put all that crap on my truck and it should shift correctly or am I overlooking something.



Also I'm aware of driveshafts input differences etc. just want to make sure it will shift correctly. Thanks guys
