Right I will not even pretend to know what I am doing when it comes to the magic that happens back there!!! But I need to remove the engine from my Van, It is an automatic and I know there is a torsion meter or something in the gearbox that needs to stay attached. Any help please?
Make sure you switch the flux capacitor to the service setting before you start...... it's up the left air intake below he condensor tube.
You need to undo the 3 or 4 bolts , can't remember how many that hold the torque converter to the flex plate, so if you look from the top of the engine on the left hand side there is a hole in the block approximately 40mm diameter , turn the engine until you see the bolt, undo it, keep turning the engine and undoing bolts until they are all undone, then remove the engine as per normal
The torque converter is a doughnut shaped lump of metal inside the bell housing. Once you split the engine and transmission you should try and keep it attached as it can easily slide off. The usual is to wire it in place until the engine goes back on. For some jobs it's probably easier to drop engine and gear box in one lump.
You haven't said what the problem is, why do you want to remove the engine. and possibly the automatic gearbox. folks usually post their problems or symptoms and get help from all the experts on here.
I'd say reading his other post it's a resto, bodywork done now engine out, probably to replace rubbers etc . I'd say take engine and box out together, give good access to tank , pipes , driveshafts, the underside of the bus! and it'll be easier to split them when they're out.
Some pics for guidance. Note these are off a 79 which is slightly different. First is the drive plate. It's got 3 bolts which undo from the other side. These connect to the torque converter in the second pic. The torque converter just slides onto splines on the box which you can see in the last pic, hence it's wired on in pic 2.
Its easier than a normal engine, when you put it back make sure that you use thread lock on the flex plate bolts.
I took my engine out complete with the auto box then split once on the floor...much easier and far less risk of the TC sliding off. Did the same refitting too
