Default Transmissions - which one?

OK, I'm confused....

For the longest time I was under the impression that the transmissions were the same between the Aero and non-Aero vehicles (B235R vs B235E)

Now that I'm looking for a used transmission, every reseller and on-line reseller tells me that the transmissions are not compatible from the B235E into my Aero?


The Aisin Warner transmission in mine is an AW55-51SN. Can someone with an 02-04 B235E car look at theirs (you can read it under the hood, look just between the neutral safety switch and the engine block you'll see a yellow tag from Aisin Warner)


I found a good looking one from an 02 B235E wagon with only 80K miles on it, but the guy insists that it is not compatible with my car...... grrrr!

Follow the link and scroll down to the auto transmission 9-3/9-5. Some good info there.

Great info, unfortunately for my 03 it stops a year early!

What I was able to find was this transmission on ebay from an 03 non Aero:
http://www.ebay.com/itm/03-SAAB-9-5-...d6af4c&vxp=mtr

If you look at the ID plate you will see that is is labeled

AW55-51SN
Type: FA57A04
Saab PN: 54 41 316

Mine is:

AW55-51SN
type: FA57C02
Saab PN 54 41 324

Does anyone know what the differences would be in these? As far as I knew the only difference between the Aero and non-Aero was the paddle shifters, but I suspected that feature was done entirely in the TCM and not the transmission.

Default WIS speaks...

To the best of my interpretation of the information provided in the WIS for year 2003, this is how it breaks down the numbering :

F = front wheel drive
A = Automatic
5= five forward gears
7= Overall ratio, top gear (2.5 for 7)

A04 = built in January 04
C02 = built in March 02

As for the Saab part number, I do not have this information but I will continue my research.

The WIS also shows the same gear ratios for all motor types for 2003, from B205E to D223L and including both B235E and B235R.

This is the extent of what I found in the WIS.

The EPC also shows PN 54 41 324 for a 2003 B308E also marked FA57C02. Looks like one out of an '03 6cyl would work.

Here's one that might do it:

And another, bit pricey but low miles:

This is confusing as hell......

First, I got my WIS and was able to look a lot of this stuff up. The type designation code (above) is almost correct

FA57 is FWD, Automatic, 5-speed, 2.5 final ratio as indicated. It says that this designation is used from "MY 02 on" so it looks like there are lots of FA57's out there.


The C02 is actually the rev level (the date code is in another number) C is supposed to indicate "Automatic transmission adapted for various motors" and B is supposed to indicate "manual gearbox" but there is no listing for A which I found on that transmission on ebay (link above)

the lower number on the tranny is the serial number with date code, again the ebay link has 03BV551203 which means 2003, February, V=FA57 and the rest is the serial number. That transmission is advertised as a 03 (no specific car listed) so that makes sense.

Now when you dig into the details on the transmissions, there is NO indication that there is a different transmission for the different engines. The gear ratios are the same for the B205, all of the B235 variants, the B308 and the D223. The WIS also says that the blocks are the same for all of the 235 variants, so I know that the transmission from a B235E will bolt up to a B235R. I don't know enough about the B308 but numerous sites advertise that the transmission from the 6-cyl is compatible with the 4-cyl E variants, some advertise it's compatible with the R Variants.

I don't have the EPC to look up part numbers so can't tell what the difference is between the 54 41 324 that is in my car and the 54 41 316 that was on the ebay transmission linked above.

here's another one from a guy who says it will fit any 01-05 9-5 4-cyl. (I'm not sure he's right since I thought the 01 had the 50-42LE in it)

The plate on this one is identical to mine (part number, designation)

According to the EPC here's the info on the two part numbers:
The 54 41 316 marked FA 57A04 states 2003 B235E or B308E.
The 54 41 324 marked FA 57C02 states 2003 B235R or B308E.
I would be most interested in the one where the plate info matched exactly.

that's just plain weird....

One is for the 235E and 308E, one is for the 235R and 308E.

So clearly it'll bolt up. I just can't find out what is the difference between the two. Transmissions for the 235E are cheaper and more plentiful...

Also, there is no explanation in the WIS for the FA57A04 transmission.

The doc says "C" is an automatic and "B" is a manual but nothing about an A. here's a link to a clip from the WIS describing the transmission designations

I looked through my WIS and Googled for an hour, no luck. Try calling a trans place see if they can tell you.

When at dealer yesterday asked the question about the two transmissions. At first the service guy said "no way that the B308 and any B235 share the same transmission" and then he looked it up.... color him surprised!

Net result is that there are two part numbers as indicated above, with the FA57A04 and FA57C02 type designations. and no idea what the A means

I'm still trying to chase my transmission problem, but I do think that I finally figured out what is the difference between the FA57C02 (in my Aero) and the FA57A04 ( in other cars)

What confused me was that the FA57C02 is used in the Aero and some B308E cars, while the FA57A04 is used in the non-Aero 4-cyl and some B308E cars.

I realized today that a new transmission comes with the neutral switch on it, which is different between the cars with the geartronic transmissions (i.e. paddle shifters) and the cars without, primarily because it has to sense the "M" position on the shifter. There is also some linkage that goes on inside the transmission that is connected to that lever, but I think that the only thing going on there is the "park" locking of the transmission.

So, if the geartronic was an option on the B308/V6 cars, then they would have received the FA57C02, otherwise the FA57A04.

Now the question I have is if I got a FA57A04 could I put my neutral switch on it and essentially turn it into the transmission for my car?

So some questions for the group:

1: can someone with the EPC try to verify this theory?

2: was the V6 offered with the geartronic transmission as an option?

Thanks everyone!

^^^ Yes, the wife's 2003 V6 has the 5 speed Sentronic tranny with the paddle shifters on the steering wheel.

It would be REALLY interesting for you to go look at the transmission, just by the neutral switch there is a yellow tag. The type designation is on there.

you can see it without taking anything apart, just use a long stick or screwdriver to push the wires out of the way and a flashlight.

They're all going to bolt right up and drive the car fine. I use the lowest mileage 04+ tranny I can find, they have fewer valve body issues. I've absolutely mixed them up between linears, aeros, and v6 cars without issue

Too bad we're on opposite sides of the country, I'm pulling a 60k tranny out of a 2005 9-5 parts car this weekend (body damage)

NE Sweede

That is very interesting because everyone selling them tell me that the 04+ won't fit in my 03 Aero. In fact, I had a good line on a 07 FA57C05 (three revs later than mine) and decided to back away.

If you're willing to ship it, I'm sure we can work something out. That'll mean that you have to put it on a skid and band it. If you can drop it off at a depot on the skid, I can pick it up and the shipping isn't too bad.

PM me if you're interested in doing something.

Very interesting.... disproves my theory since I had thought the paddle shifters would drive to the C02 and the A04 was the one without.
