does anybody know where the T-5's center of mass is? i'm just about ready
to pull the transmission from my mustang and i need to figure out where to
put the floor jack to support the transmission.

thanks.

Try a trick I use (takes two people though.) Support the tranny under
the forward part of the case. Then loop a length of rope around the aft
section where the shifter mounts and feed it through the hole in the
transmission tunnel for the shifter. Then when lowering the jack, have
someone lower the rear section of the tranny using the rope. This sure
beats balancing the tranny on a floorjack!

Is the date on my workstation wrong, or is it really April 1?

You know, sometimes you really are better off taking your car to the
dealer for service.


But if you insist..

When I pull a T-5 I take several precautions. First, I degrease the
transmission with Gunk and soapy water. Then I clean it with acetone
(gunk leaves a residue). After I mask the bottom of the transmission
with high quality masking tape, I apply blue layout fluid. You want
to do this several days in advance to give the layout fluid plenty of
time to dry before indicating the location.

Of course we would need a full print of your jack to do this
correctly. We'll need to evaluate how the surface area and points of
support will interact with the mass of the trans. Once you have
determined the location, mark it with a pair of calipers. I
suggest you set up some plumb lines as an exact reference.

Don't forget that the motor mounts sag with time. This will effect
the installed angle of your transmission and the weight distribution.
Do you have the small bearing or large bearing T-5? The large bearing
results in more mass up front.

Don't do this job quickly, as sloshing the fluid will throw the whole
transmission out of balance. Then you're looking at a transmission
balance job. While you're at it you might as well have the driveshaft
done.

Sometimes you just got to say what the hey and yank the thing out.
There's a fat end and a skinny end. The fat end is much heavier, put
the near jack there. If you're really worried about this, put a piece
of pipe over the shifter opening in the interior of the car. Tie the
rope to the trail and drape it over the pipe. Put the jack on the
front half and let the slack out of the rope as you lower the whole
thing down. This shouldn't be necessary with the fairly light T-5
(confident types can bench press that tranmission into place). The
toploader is quite a bit heavier and responds well to this technique
if you're working alone.

An iron case Top Loader weighs 175 pounds. Just the box; no shifter,
bellhousing, clutch, or flywheel. That's right at 100 pounds more than
a T5 or aluminum case Muncie.
