I've got a whole long list of things I am considering, but as for what I am actually going to do, I have not planned that out yet, much less made up my mind.

Dayum! Long time no see. Glad you made the progress on the car that you did, but sucks to hear of your transmission failure.
I have a question! Is it necesary to swap to an OBD II transmission, or if one of does the swap in a 94 or 95 3100 car, can we use the orignal tranny? what changes?

There is no change between the 1994-1995 and 1996 Transmission. They are all the same. The difference between the transmissions are only for the different ENGINES. A 4T60-E from a 3100 SFI and 3.4 DOHC are the same (only have different final drives). A 4T60-E from a 3800 is DIFFERENT. A 4T60-HD from a Cadillac is DIFFERENT.
The differeces are in the VALVE BODY. They are set to run by different computers. GM has 3 basic computers for all of their cars. a CHEVY computer (3100/3.4) a BUICK computer (3800), and a CADDY computer (4.9).
they are NOT interchangeable without removing the side pan and swapping out at LEAST the valve body. You might even have to swap out the channel plate, but I just stick with what requires the least ammount of work.

I thought between 95 and 96 they officially didn't interchange?
For my swap, I am talking only about a 94 or 95 3100 converted to 96 engine wiring, with a 97 PCM from a CS or lumina

The not interchanging has to do with stuff like the trip computer, and some of the engine components. I have used a 1996 transmission with a 1994 ECM, and I have used a 1995 transmission with a 1996 car.
If you think about it, there are a lot of guys updating their 1994 and 1995 OBD1.5 3.4 DOHC cars to the 1996 PCM, and they are NOT swapping out their transmissions to do it. They only swap out the transmissiong if they go to the 1997 PCM because the 1997 3.4 DOHC cars had the 4T65-E.

the 2.8 got the 440-T4 in the 4-speed cars. In 1990 or so, the 440-T4 was renamed the 4T60 (non-electronic).
The numbers and letters tell you what the transmission is.
4T60-E
4 = 4-speed
T = TRANSVERSE mounted (sideways)
60 = power rating/model number
E = ELECTRONICALLY controlled.
There is also a 4T60-HD which is the same, but the HD stands for HEAVY DUTY.
The differences is all INTERNAL. Physically, you can't tell them apart. The difference is the valve bodies, the shift solenoids, and the pressure sensors on the interior.

Every company has a different name for their transmission, but they will all mean something.
For example, FORD will use AXOD on their FRONT DRIVE CARS.
A = AUTOMATIC
X = transverse mounted
OD = OVERDRIVE TRANSMISSION.
I know my friend's for Taurus had AXOD on the pan, and that is what it was for. Another friend of mine bought a Lincoln Mark VIII LSC, and it had AODE on the pan.
A = Automatic
OD = OVERDRIVE
E = Electronic.

It does not work. The 1.5 one might work that the Grand Prix uses, but as for the OBD1 computer, it does not work.
When you start the car, it just says DIAGNOSTIC MODE.

the Aurora DIS is integrated into the climate control unit. It is all one piece and the DIS can't be seperated from it. Here is a pic of the Aurora unit. I bought one to use..... In theory, if you can seperate it, you MIGHT be able to get it to work as long as it is not tied into the BCM. If too much of it gets info from the BCM, then it will not work.    I thought I had a pic of it with the cover off, but I can't find it. I will try to get a new one later. |
