The transmission, both manual and CVT both come out separate from the engine, according to the 2000-2003 service manual.
First warning is about working around the IMA system (HIGH VOLTAGE) and turning it off.
I would HIGHLY recommend getting the service manual as there are many pictures and exact step by step procedures shown.
Before trying to rebuild my 2002 bashed Insight , I ordered the service manual and the body repair manual and was very glad I spent the money.
Check here

for the link to the manuals.
I don't think you will be sorry you bought the service manual.
The part number you want is 61S3Y06.
This is the 2000-2005 Service manual.
Unless you are getting into a rebuild of a complete total and replacing body panels,etc., I would say you won't need the Body repair manual.
good luck, work safe
