Manual Transmssion KM145 v. V5M21

[djschmidt605]

Hey guys,

I've got a 1987 2.5 TD LO44 SWB with what I believe to be a KM145.

I'm currently having a few transmission dramas. My 5th gear has blown out and I have difficultly shifting down into second gear. (Both VERY common problems for this transmission)

I've got a site that lists all genuine parts for my vehicle.

http://mitsubishi.epc-data.com/pajero/l044g/wntx/manual-transmission/manual-transmission-assy/29186,29177,29181/

It lists my transmission as being a V5M21.

From what I have seen the V5M21 transmission is the KM145 but with all of the common problems fixed.

What my question has become is are these transmission interchangeable? Will the V5M21 fit into my Pajero alongside my transfer case?

I'll let you all know if I hear any useful information.

Update 1

I've found more information regarding these transmissions.

http://www.lilevo.com/mirage/Manuals/RWD%20Manual%20Transmission%20R4M21-R5M21-V5M21%20PWEE8914-ABCDEFGHI%2022A.pdf

This site lists the KM145-9 and V5M21-4-Q as being available on the same engine (4D56 TD). There are no significant differences listed in the (significant difference section). Additionally these two transmissions share the same exploded view.

My main concern was not with the bell housing as I've been told with certainty that they're the same. I was more concerned with the transfer case matching up. Until I found this:

http://autopartmaster.com/en/?action=catalog_show&cat=mitsubishi&t_id=34891&id_pic=63949

This lists the same transfer case as fitting the KM145 and V5M21.

Will post updates as time goes on.

Update 2

Ended up not getting a whole new transmission. American Power Train Warehouse sells everything needed to rebuild the KM145 gearbox, including everything involved with 5th gear (the most common to blow out and my initial issue).

How did it all go in the end?
