Will GM 200r4 work with factory floor shift location?

Well it wasn't easy as pie but it wasn't hard either. I rolled the 2004R over on it's back and removed the pan (metric bolts). Cleaned it up a little and located the spot where I want the drain plug. Of course I changed my mind a little later but I'm sure you'll put yours when you want. Just make sure you start the pilot hole close enough to the bottom of the pan. It's real easy to be fooled by the large radius on the bottom corners. If you put the hole too high you won't be able to get all the fluid out or you'll be forced to weld it up and start again. If you use a step drill like I did be sure and mark (magic marker) the step you want to stop on so you don't make the hole too big. Either way once I had the 1/2" hole drilled out I used my rat tail file to remove all the burrs (metal shaving will KILL a transmission). In fact I left the tranny pan magnet on there deliberately to catch the shaving and you can see for yourself what can end up in you tranny if you're not careful. After all that I removed a portion of the threaded area on the plug so that I could drain 100 percent of the pan fluid. Then I deburred the threads to make sure nothing ended up in the pan. Since it's going to be silver soldered I won't need the threads anyway. So now in the pics you can see that I have as much ground clearance as possible and can still empty my pan. A little wire wheeling on the solder areas and it's ready to go to the radiator man!!

PS - I also took some pics of the TV mechanism on the inside of the tranny but I'm only allowed 10 pics per post so I'll post those a little later.
