It is no problem to take off the gearbox without removing engine - worst part is to remove and put back the TDC sensor because of its location
I will try to make a small list:
Remove,
- Air filter box and hoses
- battery
- battery surroundings included transmission computer
- both sides inner plastic wing mud covers
- loosen and pull out both driveshafts from the gearbox by removing the 2 big bolts on the damper mountings - you have to loosen the right hand engine mounted driveshaft bearing to pull out the right hand side
- disconnect cooling hoses connected to the gearbox cooler
- disconnect the gearbox electrical connector and put aside the cables
- unclip carefully the gearbox control cable (FRAGILE!! do not twist too much or it may brake off)
- Locate the TDC sensor and loosen it by unscrewing the 10mm bolt (difficult area to work - it will help to take off the control cable mounting)
- take off the body earth strap connected on the gearbox end
- unscrew the converter 3 bolts from underneath (starter plate) by turning the engine for each bolt
- drop the gearbox top mount (strap the engine first) allowing the complete assy to tilt down a few cm
- loosen the 5 bolts connecting gearbox to engine
- pull the gearbox from the engine approx 2-3 cm and drop it down carefully.
It is all about creating enough space so you can locate bolts and removing it without destroying anything. Take your time and you should be okay. Remember the gearbox weight is 90 kg so handle with care!
Use locktite on the converter bolts when putting back together (book says probably to renew them), also measure the triangle metal plate against the engine to make sure it is not bent -creating a twist in the rotation of the converter - it must be straight. Also make sure it is not cracked or damaged.
On the converter center it is a plastic ring - do not loose this one.
I hope some of this is understandeable, but once you start with the job it is pretty much traight forward.
Please come back if you have problems and/or when you are done.
