Look on the mainpage, a lot of effort has gone into those pages of info for you. Please take advantage of them.

The 95-00 Neon Trans is somewhat different. 5th gear is different and the final drive is also different. Unless you are pushing over 10lbs of boost the Neon trans, at least the 3.55 trans is not really a good option.

Now if you can get your hands on a 2001+ neon Magnum trans then it is the same. See the specs on the FAQ main page for any differences.

To identify the correct trans look on the endplate, there will be a silver tag. On that tag you will see the ID number as well as 3.55 or 3.94. You want 3.94

The srt-4 trans is very different, dont try to use it.
