I think I have already read that when I was doing some other research. Looks like it's a very limited range:
need pattern name, if any -
Apparently not the same pattern as LA 2.7L V6, 3.2L V6, 3.3L V6, 3.5L V6, 3.8L V6, 4.0L V6 (maybe on 3.3 and 3.8)
Looking for a truck/RWD manual application, the Gen 1 Dakota used the 3.9 Magnum V6.
Gen 2 Dakota apparently used the 3.7 PowertTech V6 and 3.9 Magnum V6.
If the 3.8 is the same, then the 2007-11 Jeep Wrangler (JK) used it, but from what I've read it was only a manual offering with the 3.6 Pentstar V6, which of course is a different pattern.
Having read though the linked thread, one relevant post was this one:
"The Mitsu V6 bellhousings are almost identical to the LH V6 bellhousings. The principal differences are that:
- The starter location was moved downward due to the structural webbing present on the Mitsu V6 block between the bottom left engine bolt hole and the left cylinder bank lower bolt hole.
- A water channel was cut into the top of the bellhousing, between the left and right cylinder bank upper bolt holes. This was to allow clearance for the Mitsu V6 water pump inlet pipe."
If that is true, then this opens up more possibilities. The Mitsu 3.0L 6G72 was used in the Sebring as an automatic only. Looking at a list of vehicles that used the 6G72 in a RWD application, the newer ones were the Mitsu Mighty Max P/U 1990-96. The 1988-90 Dodge Raider (a/k/a Mitsu Montero) also used it, as well as the G54B that was in the Conquest. Visitng www.car-part.com I saw a 1990 Montero offered a manual trans with the 3.0 V6. The next generation Montero did so as well when I checked a 1996 model. For a 1996 Mitsu P/U, the manual trans did not show as offered with the 3.0 V6.
The largest 3.0/manual listing on car-part was for an example vehicle of a 1990 Dodge D-50 PU. I found several pages of manual transmissions for this vehicle, several of which came from a Montero. Many were listed as 4WD.
When I specifed just a Montero, I found a total of 4 manual transmissions for sale for a manual 1990 Montero. It depends on how you search as to what you find.
Expanding upon this, the 6G74 is the same pattern, and is used in the Montero Sport, which is still in production although apparently not sold here. Using an example vehicle of 1999, I found a 4WD 3.0 V6 manual transmisson listing. There were only 6 of them in the US. From 2000+ the only trans listed was an automatic.
In summary, the best option at this point is a manual transmission from a 1990-96 model D-50 PU or Montero.
