If you have a car equipped with an OHV engine already, you can retain your existing transmission. If you are swapping to a car with a DOHC engine, you need to swap your transmission as well.
Options for auto are the 4t40e (4 speed auto) that comes in the J, the 4t45e that comes the N body cars. 4t65e or 4t65HD these transmissions are found in W and C body cars, and the 3t40e which is strongly NOT recommended
see what happens when you do a little bit of research? just imagine if you did more what you could learn.

I know what trans mate to it I was wonder which is the best
The higher the number at the end of the transmission is stronger.... 4 means the number of speeds T means transverse and end number if i remember right is a torque rating or something like that so it all depends on what your doing with your swap....

Trannys usually don't mate because lolsexchange.
For the 3800, the 4t65 (e or HD) is the best, but it's going to be a tight fit in the J-body. It's a very large transmission.
If you were to do a 3400, a 4t45e would be the best, because not only will it fit better than the 4t65, but you can also get an ECM that will already run that transmission with the V6. The biggest problems with the V6 swaps an automatics is that you can't just flash an ECM for a new transmission. You have to flash it from a vehicle that came with that engine/transmission combo. This is why you can't do a V6 swap with the 4t40e found in the J-body. The shifting is different, so if you try to hook up an ECM flashed for a 4t65 to a 4t40, it won't shift properly.
Regardless, you'll need to do at least some fab to swap either a 4t45 or 4t65 into the J-body. They do not mount the same.
I had a 3100 with 4t60e, and it didn't require any special modifications to fit. Had to use j-body axles with the grand am cups that to go into the transmission if I remember right.
I used the part of the 3t40 trans mount that bolted to the frame, and the 4t60e mount that bolted to the trans. Anytime I turned full lock and gave it more than just a little throttle the driver axle would literally blow up, but I believe I had the wrong length axles in it.

I can attest to that! My swap is using a 4T65HD and it is a beastly trans to try and fit. However, it does fit.
Whats up people?

You meant the 4t45e?
The 4t60e and 4t65e are both larger than the 4t40e or 4t45e. I don't see how you could have used the 3t40e mount on the 4t60e
Also, since you said you needed the Grand Am cups, this even more points to a 4t45e, since the 4t60e was never available in a Grand Am.
serious dude at the top of the page theres 2 thread that will answer every question you have

Listen to this guy. He wrote the book!
He has been invaluable and very patient with all of my questions. I am just about to start the plumbing stage and then electrical which I am sure I will have a ton of questions for him.
Thanks

I've ready the whole sticky and I'm listening to him as well .... But I still had questions. This is the first swap I've ever done. And if I don't understand somethings I'm gonna ask them
One more question that I didn't see the answer in the sticky.... I have a 97 z24 I'm going with the 2.2 auto trans will I have to swap the tranny harness? For the 2.2? Or will the harness that's there work?

To answer your question, the transmission hookups are on the main harness, so the plugs will already be on the 3x00 harness. However, I don't think that there is an ECM flash available that will properly run the 4t40e trans, which is what is on the 2.2.

Yes it was a 4t60e, and yes it came in a grand am.

That's because you must fabricate your own mounts.
Axles ? Using ones from jbody or a custom axle ... I was told I couldn't use the automatic trans from 2.2
Depends . . . Does your engine mount in the stock position? If the trans is in the right spot you can use the original jbody axles. If it is not then you must use custom axles.
Whats up people?
serious bud decide what you want then getthe answers
you the axels for the transmission your using you can't use 2.2 on a 65e you have to make the axels using both axels from both car.
what parts are you using and get them then ask more questions but get your engine and transmission then go from there
JBO since July 30, 2001
I have the engine but getting another trans cause I learned I can use other so I was asking about axles so I can get those if I need to pick them up or order them... I'm trying to get a step ahead
