Changing tranny oil in 95 Bronco XLT -

I want to change my Bronco's tranny oil, including the oil in the torque converter. I'm going to siphon out what oil I can through the filler tube, then drop the pan and change the filter and gasket. After bolting the pan back, I plan to drain the torque converter by disconnecting the oil cooler line, cranking the engine to pump the remaining fluid into a bucket. This is the step that makes me nervous. Will running the motor (and tranny) to pump the tranny dry damage the transmission? I plan on killing the motor as soon as the oil stops coming out. I've never done this before, and if it's an iffy procedure, I won' do it. Anyone with experience doing this? Thanks, John No need for all of that hassle. The converter should have a drain plug. Remove the |
the back of the motor. Bar the engine over by hand. You will see the drain plug close
to one of the converter to flywheel nuts. It looks like a 7/16"(?) bolt head, but it
is actually a hex head pipe plug.

clean fluid. That way the converter is drained and flushed. THEN drop
the pan and change the filter, re-assemble and top up. Yes, you do
"waste some fluid" but you get a total flush and fill.
Or you can do the filter stuff first and save a bit of fluid, with the
possibility of a very small amount of crud staying in the pan (very
slim chance, very small amount). You choose.
It will NOT CAUSE DAMAGE TO THE TRANSMISSION. It will NOT cause the
tranny to fail. I've done it HUNDREDS of times.

Remove the tin inspection cover on the front side, bottom of the bell housing. It's right under the back of the motor. Bar the engine over by hand. You will see the drain plug close to one of the converter to flywheel nuts. It looks like a 7/16"(?) bolt head, but it is actually a hex head pipe plug. Trust me, the stock Bronco converter has no drain. Haven't seen a |
years. Why? because it's not required in manufacturing and would raise
the cost of every vehicle by about a nickle.

drain. Probably the last American cars to have a drain on the torque
converter were some rear wheel drive Fords from about the mid-90's,
maybe just a year or two earlier. I think you can still find a torque
converter drain plug on a mid-90's Mustang if memory serves me right.
(and it quite often doesn't)
GM and Chrysler were even more shy about a drain plug on torque
converters, although a lot of <GOOD> tranny shops would drill out a
hole in the torque converter, tap it for threads, hook up a machine to
flush out the torque conveter while the tranny was being rebuilt, and
when all was done, put a plug back in it. Those days are long gone.

If it is an AODE/E4OD it most certainly does have a drain plug. I'm pretty sure the
'bigger' trans (4R70W?) also had a drain plug until about 2001. The AODE was behind
the 5.0L, and the 'bigger' trans was behind the 5.8L. (usually).
BTW, some plugs are accessed through an access hole in the bottom of the bell
housing, I forgot to mention that little detail.

I wouldn't worry about what little fluid is left after you drain both
the tranny and TC. If you want to clear the cooler you can unhook the
line that connects to the top of the radiator end cap and the tranny
end of the one that connects to the bottom. The stock cooler only
holds a few pints anyway.
