Torque convertor etc should be the same..don't see why it should be different

Yeas its just a nut and bolt job,but heavy stuff...certainly wouldn't advise doing it without help

you unbolt the torque converter from the drive plate and push it back onto gearbox then remove whole unit as one,watch the weight though as with all the fluid and the converter it is quite a heavy lump

I Have a vauge recollection something is different on the TD....think it is 'just' the bellhousing you need to swap.  Possibly TC too?

Both JB, Bellhousing and TC from the original box on to the new box. They are both AR25's so the same :y

The unit weighs about 85 kgs so you need two people in the street or a garage hoist and so on.

Two areas to watch out for. 1st make sure you have disconnected all the electrical parts of the loom to the gearbox.

second when you remove the box or when you are putting the replacemnet in it comes off and goes on "horizontal" otherwise you can damage the spigot coming out of the engine.

watch out when removing and fitting the electrical conecting plugs as you can easily bend the conectors or push the socket into the gearbox (especially if the plastic on the socket as gone fragile)

Unbolt the torque converter from the driveplate and remove it with the gearbox. Install it with the gearbox when you refit. Otherwise, you run the risk of damaging the bush and oil seal where the TC nose joins the gearbox.
