Does anyone here know for sure if a 2WD VG Pathfinder 30A trans will bolt in without modification on our cars? I've searched around and found conflicting views on the subject. The transmission (mainly the rear housing) looks a bit short and the shifter does not look like it is mounted at an angle like the Z31 30A, but a few people have said that it will work with no issues. I've been looking for a cheap and easier to find alternative to a Z31 transmission, and right now a 240SX 71C looks to be the way to go, but I would prefer a 30A. Any input is appreciated.

- I have not put one in personally*
I have seen 5-6 people use Pathfinder 30A's and said nothing of differences. As I understand it there are no differences but the gear ratios. Those are very close and not worth worrying about.

Not to thread jack, but which pathys came with 30A? No z31t's anywhere near here, but many pathys.

I believe all the VG33 powered Pathfinders/Frontiers/Xterras came with the 30A. Also i'm pretty sure some of the VG30 Hardbodys could come with the FS5R30A as well.
Anyone know the difference between the FS5R30A and FS5R30B transmissions?

placement of one of the switches on the passenger side is ahead of the center section, and one behind.
far as i remember, on the R30A- they're close together. externally they look the same.
not sure about bell and starter position.

I know its off topic of the 30A, but do you know the difference of the 71B and 71C?

Ok, I thought I had posted these pics up a long time ago but I guess not. These are pics of the pathy/pickup transmissions and one is of a late model z32 r30a with a pickup bellhousing. I have no idea if these work or not in a z31 because I have always been deterred by the fact that they don't have the angled shifter or right looking shifter plate at all....
Also, according too many sources all r30a are 29" long BUT I am pretty sure the z31's version is longer because we all have to lengthen the DS when installing a z32 transmission. The truck/pathy transmissions are in FACT 29" long I have on here at my house currently so please don't tell me I don't know what I am talking about.

If anyone actually bolts one up into a z31 please take pics so I can see what the shifter looks like in there!
nismopu: (2010-07-02 16:44:57)
One has a shifter plate and the other looks like an l-series with an external shifter rod attached directly to the shifter itself. 720 pickups had the 71b and 87 HB's had the 71c's but internally they were the same transmission.
BLOZ UP: (2010-07-02 17:26:51)
Doesn't the KA frontier have a 30a too?
nismopu: (2010-07-02 18:08:00)
no, the KA tranny looks like this and its a 71c variant, a bit stronger than the other 71c's and looks the part too!

Mmmm, good info here. Me likey…
nismopu: (2010-07-03 16:33:03)
Oh, and you can see the differences in the shifter plates like I was talking about. I think fs5w71c's shifter could work with the z31 r30a's but I dont think they will work with the pathy/truck transmissions. I may have to pull the shifter off the frontier transmission and give it a try, since its the only 71c I have out of a vehicle right now.
Geoffs89Pathy: (2010-10-25 07:15:39)
how bout a z32 tranny with a pathfinder bell housing in a z31? shifter issues? drive shaft issues? clutch issues?
nismopu: (2010-10-25 13:57:20)
Seriously? The first picture I posted is of what your describing. Its the same as doing the z32 tranny swap with the exception of having to buy the unexplainable maxima flywheel.
Geoffs89Pathy: (2010-10-25 14:55:42)
sorry i wasnt sure what the 30a was reffering to exactly, i didnt know the part #s.
does it bolt to the existing crossmember or do i have to get a xmember from a manual z31 or do i have to make a custom one?.
thanks.
comrade_charlie: (2010-10-26 16:07:46)
I have a 2wd 30a out of a 2door vg30 pathfinder sitting in my building if anyone wants measurements or if someone wants me to mount it to a vg30 I have laying around
Geoffs89Pathy: (2010-10-26 17:06:52)
no one has answered my crossmember question yet. does it bolt in

Wd21(95 and earlier) pathy got the 30A also

nismopu: (2010-11-07 01:19:48)
If you follow the z32 install guide it will be the same for the pathy r30a. They're the same length and the mount is in the same location.
stprasinz: (2011-09-10 19:49:02)
Shifter is gonna be 4" off.... But drive shaft needs 4" longer.... I just may find myself a different intake (ala pathfinder, that I have sitting right here), and us ethe headers I just bought And slide the engine back 4 inches.... then until I do the s13 rear swap I could use the factory shaft too..... :twisted: I think I may like the end result.....
Hairyballs: (2013-09-12 02:25:03)
the hardbody KA24 71C is in fact a WEAKER! transmission and the dimensions
Overall length: 30.5"
Bellhousing to center of trans crossmember bolt hole: 22"
Bellhousing to shifter plate: 22"
the 71C is 36" long.

Which parts specifically are weaker?
michaelp: (2013-09-12 15:31:18)
This thread is about the 30A, though. And its well known that the newer *240SX* 71Cs are stronger…as for the Hardbody 71C, it wouldn't surprise me if it were the same. How did you determine its weaker by dimensions?
slammedfc: (2013-09-12 19:16:51)
So you mean i dont have to pay "exotic japanese car" tax on a 30a now? Thank god.... My 71c has the infamous second gear grind so bad i'm certain my "used to be clean internally" gearbox has metal shavings in the penzoil now.... I'll give this a go. 2dr 5 speed a rare find though. Most are auto/4wd that i come across.
Hairyballs: (2013-09-13 03:57:14)
i took them both apart the gearing on the hard body 71c is phyiscally shorter not the gearing the gears them selfs 1st 2nd 3rd 4th 5th are all weakers.
4th gear on Z31 71C is 22mm in length and the hardbody is 19.7xmm in length (the length from front to the rear.)
reddzx: (2013-09-13 13:32:54)
Size does not always indicate weakness.
Hairyballs: (2013-09-16 18:42:20)
what i mean to say is the thickness is less.
Tempast: (2013-09-16 19:54:30)
So? Take a look at most transmissions. A bike is a good example. The older bikes (say 1970s CB750) have massive gears, very very thick and heavy, but the engines only make about 67 horsepower. Then there's the new bikes, an example would be a Kawi litre bike. They have very very thin gears in the transmission, yet are making about 197 horse. The gears are made differently to allow it to be stronger and not just strip when you dump the clutch at 9k. Simple as that. Material and treatment.
