Mitsubishi 2.5L & 3.0L V6 engines AND 5 speed manual transmission

Hello,

I am looking for some information.

1) The 2.5L engine is designated 6G73, what is the designation for the 3.0L engine?

2) The designation for the 4 speed auto in my Sebring is A604, what are the designations for ALL of the 5 OR 6 speed manual transmissions that will fit / work with the Mitsubishi 2.5L & 3.0L V6 engines?

3) In my search I have found transmissions that mount on the passenger's side instead of the drivers,
are there any vin codes or models this is standard?

Thank You

The 3.0L is designated 6G72, but there are many variants of it.



The 5 and 6 speeds used in the Stealth and 3000GT would work.

The 5 speed used in the Neons will work. (The 2.0L and 2.4L I-4 have the same bellhousing bolt pattern.)

The 5 speed used in the minivans will work.

Not sure of the AXXX designations.


As far as I know, the only vehicles that are arranged with the trans on the right side of the engine bay are the 95-00 Sebring and Avenger coupes... Not sure of the part number differentiation.

The Neon and minivan 5 speeds mentioned above would fit the 2.5 (Chrysler) 4 cylinder NOT the 2.5 (Mitsubishi) 6 cylinder.
Chrysler offered a 3.0 5 speed in the following K based cars: LeBaron, Daytona, Shadow, (Sundance) Duster. The Sebring GTC convertible and the Startus R/T sedan used the 2.5 Mitsu 6 with a 5 speed. As far as I know all these cars used the Chrysler standard of engine on the pass side and trans on the driver's side. It's the Mitsubishi (and Diamond Star) cars like the Startus and Sebring coupes that used the reverse set up (Hyundai too).

There are no six speeds used with these engines in any Chrysler/Mitsubishi FWD application I am aware of. Just the Stealth/3000 RWD/AWD setup.
I believe the 3.0 used a A543 transmission for the K based cars.
The Sebring GTC and Stratus R/T used an NV T-850.
Hopefully those are correct or someone will correct them for me.

If that's the case, how come you can swap automatics between the above models??? They wouldn't change the block's bolt pattern to suit the transmission...

Also, yes, that's true about the 6-speeds. However, the shaft that supplies power to the rear axle can be removed and opening sealed/covered, resulting in a FWD trans...

You can't swap a transmission for a 2.2/2.5 or 2.0/2.4 to a 2.5/3.0 V6.
The internals may be the same but the bellhousing (which is an integral part of the case) is similar between the 2.2/2.4 and 2.2/2.5 4 cylinders, but quite different for the 3.0 V6.
Here are some of the patterns:

Thank you for your help.


O.K., The 3.0L V6 is a 6G73.

According to Wikipedia it was in the following cars

1995–2000 Chrysler Cirrus
1995–2000 Chrysler Sebring
1995–2000 Dodge Stratus
1995–2000 Dodge Avenger
1990–2002 Mitsubishi Diamante
1993-1996 Mitsubishi Galant(E88)

The manual transmissions I can find for the above cars are
A543
A568

The T350(A578) and the T850 I have only found on 1.6L 2.0L and 2.0 R/T, Neons and GM subcompacts.

>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>.

I have not found

1) image of the engine to trans bolt pattern for the Mitsubishi 3.0L V6.
2) case numbers for the transmission to match it to a Mitsubishi 3.0L v6.
3) Adapters to swap a T850 or a newer OR better model to the Mitsubishi 3.0L v6.


Does anyone have any info on this?

No.

The 3.0L is the 6G72.

http://en.wikipedia.org/wiki/Mitsubishi_6G7_engine

The block, however, is externally identical to the 6G73 (2.5L). In fact, all of the 6G7 series engines are very similar. The 3.0L, 3.5L, and 3.8L can be interchanged with the 2.5L with little or no modifcations.

According to the sources above, the transmissions used behind the I-4 engines are NOT compatible with the 6G7X motors...

The later engines require a crank sensor. There is no provision on the early 3.0 5 speed (the A543) for the crank sesnor.
The later 5 speed (used in the Sebring GTC and Stratus R/T sedan) which maybe the NV T-850 would have a provision for a crank sensor.

Could you not drill you own hole to mount it???

Is that the number used for the transmissions that go on the passenger side of the car?

My 2000 Sebring Convertible (a cloud car, not an Eclipse variant) has the trans on the driver's side and it is most definitely a 41TE(A604) model.

Also, I believe the OP has a 2.5L in his car currently (at least that's how I read it).

On the Chrysler designed cars, I believe they used Chrysler computers to control the Mitsubishi engines. On the Mitsubishi designed cars, they used Mitsubishi controls. That's something to consider. I don't know if the engines were made differently to mate to the different transmissions or not.
 
#17 ·
My 3.0L is out of an '05 Ecplise. It did use Mitsu electronics, but they are all easily removed and swapped with those from a Chrysler engine.

The cloud cars are mostly Chrysler, I can't speak to the Eclipse variants much, though...

Just to clearify what I am trying to do. I would like to swap the Automatic (A604/41TE) in my

1997 Chrysler Sebring convertible JXI (Mitsubishi 2.5L V6/G673)

with a 5 or 6 speed manual transmission.


The 6G72 engine from 1997 and newer were available in

Plymouth Acclaim/Dodge Spirit
Dodge Caravan/Plymouth Voyager,
Dodge Dynasty,
Chrysler LeBaron,
Chrysler TC,
Chrysler New Yorker,
Dodge Daytona,
Dodge Stealth,
Chrysler Sebring (Coupe),
Dodge Stratus (Coupe),
Dodge Shadow ES,
Mitsubishi GTO (aka 3000GT)/Dodge Stealth
Mitsubishi Eclipse
Mitsubishi Galant
Hyundai Sonata
Mitsubishi Diamante
Mitsubishi L200
Mitsubishi Challenger(aka Montero Sport)
Plymouth Duster "631" cast into bellhousing for 3.0L (presumably Mitsubishi V6)
When used by Hyundai the SOHC version was called G6AT (3.0S)
Mitsubishi Magna, Mitsubishi Triton, Mitsubishi Challenger.

I have found that the 6G72 has three versions

SOHC 12 valve

SOHC 24 valve (the version refered to in this topic)

DOHC 24 valve (don't know if the bolt pattern is the same as above)

I am currently trying to find a source for info on which ( if any) of the above listed cars came with a
6G72 & 5-speed/6-speed combination.

I am still looking for
1) The designations for the 5 OR 6 speed manual transmissions used with the 6G72
2) image of the engine to trans bolt pattern for the Mitsubishi 3.0L V6(6G72).
3) Any numbers on the case of the transmission to match it to a Mitsubishi 3.0L v6 (6G72).
4) Maybe an adapter to swap a manual transmission to the Mitsubishi 3.0L v6(6G72).

Does anyone have any info/ideas?

NEED HELP MYSELF!
I am trying to find out what transmission fits 2003 Mitsubishi eclipse 3.0 manual 5 speed. WHAT VEHICLES HAVE THIS TRANSMISSION IN IT!?Any help with where a cross reference for cars make model and years that fit is what I need. For the junk yard. Any help greatly appreciated
 
#20 ·
Those engines all have the same bolt pattern.

The A543 5-speed will fit.

The transmissions from the Stealth/3000GT are on the wrong side of the engine bay to work in the Vert.

I've done the 3.0L swap, and a bunch more, to my 2000 Sebring Convertible, so if you need any help, let me know...
 
#26 ·
Was just thinking about a V6 pt. Is it true that those V6s were oil burners? Thats what has been said about a few round here.
 
#23 ·
I don't have the links handy, but there are a number of threads on http://www.aseclub.net in regards to folks not only swapping 3.0 (and 3.5, and 3.8) Mitsu V6s in for the 2.5 in the Avenger/Sebring coupes, but for getting a 5-speed manual to work with the 2.5L V6.

If I recall, a custom "crank sensor trigger wheel" is involved.
 
#24 ·
Hi can some help me . I want to swap my 5 speed box for a 6 speed. The Pajero is 6G72 motor 12 valve version. What gear box do I need. Also the transfer case needs to be on the right side of car when your looking at it from the front
 
#25 ·
I think you'd have better luck on a Mitsubishi forum as these motors were more common in cars, not SUVs, in the Chrysler lineup.
 
#27 ·
I think the 4-cylinders used a different bolt pattern, so you'd likely need a trans and engine.

I have a newer (2005) 6G72, an SOHC, 24V variety. It does not burn oil.

There are numerous versions of this engine, however, so what is true of one may not be of another.
 
#28 ·
Also, if I was gonna do a conversion like that, where you're talking about more than just a long-block swap, I'd look very hard at using the powertrain from an LH car. The 3.5L is a great motor, and having the engine sit in the car the right way without requiring a RWD conversion also is a big plus, IMO. I would imagine that there is a way to swap/adapt the entire "k-frame" (for lack of a better word).
