TorqueFlite A-727 Transmission Rebuild
« on: March 02, 2017, 10:56:55 AM »

I was going through archives trying to get some content on the board and I came across some photos I took of the rebuild process on an A-727 transmission. I am not sure I have pictures for everything, but I will post up what I have and try to fill in the rest as time allows. Anyway, in these pictures, you will see the state of the transmission and transfercase when I pulled them out.  It was covered in sludge.  When I started the rebuild of the engine, I uncovered the primary culprit.  The oil filter adapter had no gasket between it and the block.  Typical PO fix was to just keep adding oil.

This is what you get after about an hour of scraping with a putty knife and screw drivers.

It left behind a mess and it still isn't clean enough to start work on.  So the next step is a visit with the power washer.

Now it's clean enough for disassembly.

On to disassembly.  In the next couple of pictures we point out the speedometer adapter that needs to be removed.

Then we move on to removing the tail housing.

This pic shows the bolts from the transmission mount were broke off.  So the transmission in the Scout was swinging free for god knows how long.  I have a new transmission mount for it.

The next step is to remove the oil pan from the transmission.

Here is what we found in the oil pan and on the filter.

Looks like we have some clutch material in there.

Next let's remove the shift levers by loosening the clamps and prying them apart to remove them.

Now we can remove the neutral safety switch.

And now we can remove the valve body by removing the 10 hex bolts holding it to the case.

Once you remove the valve body from the housing, you can then remove the accumulator piston and spring.  You can just lift them from the case at this time.

Carefully remove the "E" clip from the weight ent of the governor and remove the governor valve and shaft from the opposite side of the governor.  Then remove the large snap ring holding the governor assembly to the output shaft and slide the governor assembly from the output shaft.

With the governor assembly removed from the output shaft.

Tighten the kickdown band adjuster to hold the front clutch retainer stationary while you remove the front pump.

Then remove the bolts from the front pump.

IMAG0238.jpg

Then use these thread locations to attach a slide hammer.

Finally use the slide hammer to remove the front pump.
