727 Overhaul Kit

When I removed the front pump I used two all thread rods about 24" long to thread into the two holes with threads. The rods had a 2" washer on the outer end backed by a nut and a 1/2" drive deep well 1 1/8" socket on each rod in between. Slide the sockets like a dent puller slide and it pops right out. No marring of the case with a crow bar. All thread has many other uses and is good to have handy in different thicknesses.
 
I have a large "C"-clamp that I use to take the kick-down servo apart. The solid end clamps against the back of the servo casting portion of the case. Then I place an appropriate sized socket on top of the servo piston and apply against it. I use engine assembly lube on the clutch piston seals when putting these assemblies back together. I have a 4" circular disc of thin flexible plastic that came with one of my rebuild kits to work the lip of the top seal down into the clutch retainer. Failing this, you could use a thin feeler gauge. To help line up the pump for reinstallation, I thread a couple of bolts, from which I have removed the heads, into the 2 of the threaded pump holes. I slide the gasket on, and then the pump. This way, you are not trying to visually line up the holes, or possibly misaligning the gasket.
 
The toughest part of the entire build is installing the piston in the front clutch. You can not see the outer seal during installation. Put a large zip tie around the outer seal. Stick the piston in the freezer for 15 minutes. Then start the piston in the drum. Take the drum in both hands and tap it down abruptly on a piece of 2x4. The piston will start itself. Then gently work it in. Installing the servos is a little tough without a compressor tool. It can be done with large C clamp vice grips. Install the sprag springs and rollers before you install the output shaft.

Yeah, it's a bugger to get in there correctly and you need to watch which way you orient the seal because its a shaped seal and one side goes up...get that wrong and bad things will happen..
 
So now that I have confirmed my 727 is the original to my 67 Coronet RT I want to purchase an overhaul kit. From your collective experiences what company makes the most complete and best quality kits?
Can torque converters be properly flushed or being my pan was loaded with band flakes and fine metal should it be junked?

No, don't waste your time in trying to flush a converter. Crap can get jammed up in the pump vanes of the converter and once there, there they remain. Get a replacement converter and don't forget to get the transmission cooler in the rad cleaned out or by pass it with a large quality cooler. B&M doesn't make them, but they do offer a "stacked plate" style cooler. These are the best type of cooler.
 
There’s a book by Ton Hand for 727s. I read and studied that before I did mine. I was very intimidated by auto transmissions and always paid someone to rebuild mine. I can do everything else on the car, engines, rear setup. I was determined to do this. I gotta say, after I did it I was a little embarrassed that I didn’t try this before. It wasn’t that bad. Point is, you’ll do it with the tools you have but if you did these often you’ll buy all the special tools. I the clamping with 2 big c-clamps. One thing I wish I had when I was doing some of the tasks was a third hand. I had an assortment of snap ring pliers but I didn’t have the right one for the rear bearing. That fought me a little. Front servo you can use a c-clamp, offset it a little and you can load the snap ring.

I’m actually looking forward to my next 727 rebuild. Cleaning the case (outside) is the worst part of the projects IMO.

THIS is that book. It's a very good resource.
