The gearings are almost always the same EXCEPT 5th, what you probably have, MrSlick is a different final drive ratio. The eclipse has the 3.94 and some neons have 3.54 final drive. I am finishing my neon tranny swap in to the eclipse today. The bellhousing needs to be swapped, the motor mounts need to be swapped and the shifter arm does have the weight in a different place too. The wierd thing is, the 97 2gnt tranny had a weight in a different spot than the neon one but the other eclipse tranny (I think it was a 96) that was in the car after the original one went had no weight on it at all.
I also had to cut off the weight so the motor mount would go on. Dremel's and hacksaws work wonders.
