Subject: Pulling the tranny yourself
Content-type: text/plain; charset=us-ascii
Hi Chris,
You absolutely can replace your transmission yourself. Less than a year ago I had done no more than
changed my oil and done minor tune ups. Since that time I've installed an engine, pulled and resealed my tranny, installed
a flywheel, clutch assembly, starter, and so on, and now the old tranny is out and a new one ready to go in.
You do not need to pull the engine. Borrow a floor jack and jack stands if you don't own them. Jack the rear of your bus
up and be sure it is secure on the jack stands. Chock your front tires. Remove the Air Flow Meter and throttle body to
make it easier to get to the upper right tranny bolt. Disconnect your batter, disconnect the starter wires,
disconnect the shifter from the tranny, and disconnect the clutch slave cylinder. Remove the four bolts
that hold the tranny to the engine. Be sure everything else is disconnected, and then center the jack under
the tranny. Jack it up until it is firmly under the tranny. Have someone help you at this point. Have someone
"manage" the jack as you remove the four bolts (and ground strap) that hold the tranny to the frame. Do not
work directly under the tranny at this point as it could fall on you. Have your "jack manager" lower the jack just
a bit, and as he or she does so you wiggle the tranny back and forth so that it will pull out and away from the
engine. Once it is free, it will be balanced, sometimes precariously, on the jack. Carefully lower it to the
ground and pull it free of the bus.
While you're under there, now is a good time to check the condition of your clutch. If it has a bunch of miles
on it, now is the time to replace it (get a clutch assembly kit, which includes the clutch, pressure plate,
and release bearing. Make sure you also replace the pilot bearing and flywheel seal. Also replace the O-ring
that is situated in a groove in the flywheel itself (I just learned about that one this week). Before you put the
tranny back in, be sure to replace the starter bushing. It is an easy job when the tranny is out, but not
so easy once it is back in place.
Although you do not need to pull the engine, you ought to brace it somehow so as to avoid putting too much
stress on the motor mounts, especially if they are old and worn and if the tranny is going to be out for more than just
a little while.
Best of luck. If I were coming through NashvilleI would stop in and give you a hand.
