Few more???
1. When i join the zf to the lt230 do i have to use a gasket or sealer?
2. And when i join the zf to the engine do i use a gasket or sealer?
3. When i have the auto off is there any bearings or seals on the motor that i should replace while i'm there?

Thanks

I can't add to Loanrangie'e answers to 2 and 3.

I doubt there is a gasket between the ZF and LT230. There is none between the LT230 and the LT77 or R380. From memory there is a groove to let oil that leaks past the seals, to escape.

One thing to watch, if the LT230 is not originally fitted to that transmission, is the alignment dowel pins.

I can't remember the number of dowel pins (at least 2), but when the t/case is split from the gearbox, there is no guarantee which one the dowels will stay in.

Ensure that you have a dowel pin in each location and make sure that you don't have a dowel pin in both the LT230 and the ZF at the same location (otherwise you will have a lot more trouble).

1: It is worth replacing the transmission output seal and transfer case input seal. Also the transfer case intermediate shaft o rings. There is no gasket on the mounting face, nor any need for sealant.
2: The bellhousing will bolt straight to the rear of the engine with no gasket or sealer. It is not a requirement to have an air/water/oil proof seam there.
3: Rear main seal would be nice if it is easy to do.

More HELP needed.
I'm just about ready to drop out the transmission, but i carn't seen to reach the top bolts between the belhousing and the engine. How do i get to them? Does it help if i lower the tranfer case end first, tilting the engine? Will that help me reach? Or do i go in from the top and move the air intake etc out of the way?

Any ideas???

Remove the engine mounts and lower the engine down forward so you can get your hand at the back of the block.

I loosen the nuts on the engine mounts and lower the t/case end down low enough to get a socket with long extension bars over the top of the transmission.

When I join all of my bars together they extend back behind the t/case and make the job much easier.

Thanks for that, i'll give it a go.

One other ???
In the manual it says to undo the bolts that hold the torque converter in. Do i need to do that? Why?

Thanks

some info here about checking torque converter is properly seated.
