- One other thing we made that really made it
easier is a homemade fixture made out of 1”x1”x1/8” angle
iron that bolts to the pan rail and has a 2” piece
of pipe on the end that goes into the head of our portable
engine stand. Easy to rotate and stable. There are commercial
units available but for two or three times a year a homemade
one will work fine.

I will do my best
to keep this short but there are so many details that it
is difficult. I cannot emphasize enough how useful Carl Munroe’s
Power-Glide Handbook is. It literally took me from rookie
to confident with his excellent instructions that are aided
by hundreds of great photos.
First thing to do is drain the transmission the best you
can. Then remove the pan and note the amount of debris inside
-- a lot of shiny debris should prompt you to look closely
at bushings, gear sets and have the torque converter freshened.
Next remove the two bolts holding the filter on. The trans-brake
solenoid and the spool valve that goes against the solenoid
are next. The valve body can now be removed. There are three
bolts that go through it at the front of the valve body and
four at the rear of the valve body. When you lift it out
just wiggle the small steel tube that runs from the valve
body to the case and it will come out with the valve body.
This is the bottom view of an empty case (this
one is a Dedenbear SFI certified case.)

Now you can do your first measuring. I have a small
piece of angle iron I clamp to the bell-housing area
and a dial indicator with a magnetic base that attaches
to it. Line up the dial indicator so it can measure movement
on the end of the input shaft. Push down on the shaft
and try to get the dial indicator set to zero at that
point. Then push in on the output shaft and read the
dial indicator to see how much “input shaft end-play” you
have; write it down for later reference. |
