Well...here is an interesting one.

I went over to a friends house to get some pictures of a B13 (supposed) transmission to try and sell on the forums. The transmission came with the mystery motor, which we have had a hell of a time classifying. Its supposedly a Bluebird, although a bunch of stuff just doesn't add up...including this tranny.

Its the cleanest tranny I have ever seen and was labeled as having approx. 30K miles. The condiftion of it seems to support this. Marked as an SR20 transmission from a '93, I initially thought it was a JDM tranny...until I saw something kind of strange about it.

Its a hydraulic clutch.

here is a closer picture.

Can anybody tell me what the hell this is?

Looks like an automatic tranny. Maybe a 6 speed CVT tranny? Idk.

I've ruled out the automatic transmission.

There is a clutch.
There is shift linkage on the bottom.
No transmission fluid dipstick tube.
No torque converter.
it doesn't look like a auto tranny.

That's not a SR20 tranny. Do you have pictures of the motor?

No....no picts of the motor currently.

The head is marked with 53J 2L, which doesn't correspond to anything that I can find.

This is confusing the crap out of me.

Damn.... looks like a B14 LSD trans with a Hydro setup!

I want that!

I just took a wild guess since the flywheel is part of the tranny. I thought on most manual cars the flywheel does not come off with the tranny. I'm interested to see what kind of tranny this is.

Well, I spoke with Andreas Miko about this; in all his infinite wisdom he informed me that this is an old U12 BlueBird hydraulic non-LSD transmission. It can't be converted to cable clutch system due to the lack of the arm.

My boy is gonna be pissed.

that is an altima tranny i had one with lsd from an se special edition that one does not have lsd though it bolts to the sr block though some holes may no tline up maby just 2 though i tried it a while back

BlueBird = JDM Altima :)

At least you can sell it to an Altima guy wanting to put a SR20 in their car.

I suppose...

suppose its a USA (altima) trans, isnt the KA bellhousing different?

I have heard about a very rare FWD turbo bluebird trans that is supposed to be stronger than any of the other FWD SR20 transmissions. I do not know for sure if that is what you have, but it may be worth looking into. If so, it is probably quite valuable.

That is def not a US Altima trans. That is some sort of SR20 trans but I don't know whether its JDM or not and what year. I've done enough tranny swaps to know that bolt pattern on the bell housing:rofl: :rofl: :rofl:

According to Andreas Miko, it is a JDM tranny, ehich would comply with the research I have done since.

While most of the U12 BlueBirds had an AWD auto tranny, there was the option for the FWD tranny in the non SSS package, which still offered the sr20det motor option. While not unheard of, it was a more uncommon option.

While the bellhousing should mount up to a SR block, there are several problems with dropping this transmission into a USDM B-series chassis:

1: Hydraulic clutch- Unlike the B15 transmissions, there is no arm to convert this to a cable style clutch. Only the U12's came with the hydraulic clutch setups as far as I know (besides the B15 models, which are different from what I can tell).

2. The mounts are different. This can be seen in several of the pictures; that tranny mount is designed to mount to a Bluebird/Altima chassis.

3. The clutch setup on this unit may be different from other standard units. In searching for a replacement clutch, the data I found suggested that the JDM AWD SR transmissions, the CA trannies, and the KA transmissions all offered in the U12 cars each took a different clutch. There was no different option for a FWD sr transmission for a bluebird, although that was an option that was offered. To be perfectly honest, I haven't found enough solid evidence that specifies what options were available in the early U12 cars, so I am simply guessing at this point. If the car came from Australia/New Zealand, it could be from a vehicle as late as '94, which means it could even be from a U13, which were imported there while the U12s were still being manufactured.

*sigh*

So, in short, if anybody has any solid information, it would be helpful. My friend cannot return the transmission now. Its for sale if anybody is interested, although right now we are trying to figure out exactly what the deal is.

That is def not a US Altima trans. That is some sort of SR20 trans but I don't know whether its JDM or not and what year. I've done enough tranny swaps to know that bolt pattern on the bell housing:rofl: :rofl: :rofl:


im sorry to say that u are wrong but like i said befor i had one of those olready but it had lsd it is a USDM nissan altima tranny it can bolt up to the sr block also.

A KA and SR motor do not share the same bolt patern for the bellhousing so the tranny will not bolt up.

The tranny from the U12 and U13 SR20DE and Altima KA24DE share the same tranny yes but you have to change the bellhousing to interchange them.

If the tranny came from a JDM importer it is from a U12 SR20DE car. I have seen a few of these things come from Japan on motors. I never bought any as it would be to much work to put them in a B13.

If you were building a race car and changing to a Hrdralic setup would be know problem I would go with the tranny but I would also buy a USDM Altima LSD tranny and switch bellhousings.

If you were to put this tranny in a B13-B14 you would have to switch to U12 and or B15 hubs becasue of the larger spline of the axles shaft. Basically a complete brake, hub setup from one of those cars. You would have to go 4 x 114 if you did so but like I said I would do this on a race car not a street car.

It is SR20DE fwd hydraulic gearbox
I have used on my Sentra GTiR conversion
required a lot of effort to fit..

it is 50 Series Gearbox mean using big spline
you can fit up to 9" clutch size without any issue
which is same with one Maxima clutch

It not neccesary from U12
it can be U13, P10 or Those older wagon like Nissan Largo or Praire
it have long gear ratio..
top speed i try before on my Sentra is 250kmh at 6800 kmh

This gearbox is basically a 2WD GTiR gearbox and will take an aftermarket GTiR gearset. As stated, it is much stronger than a 32A/V gearbox.

What did you end up doing with it?
