727 vs. 904???

My 904 seems to go out too often. My car weight is 3,700 before the stereo, amps and subs went it, lol. With a 340 and open windows on the freeway I need a powerful system if I wanna hear the tunes. Its built with red clutches, ect. Its back at the shop right now! The trans guy brother was like 5 years ago telling me the 727 is much stronger and easier to adjust the shifts for the right firmness for street use...but I needed that 25 more hp:pale:

Oh, the shop isn't ripping me off, stuff is sometimes repaired free or cheap.

3700 pounds? what kind of car? That is getting up there for a 904 if you have any power, especially if you ad a couple hundred pounds of stereo, a passenger and your self to that 3700.

The way you drive also has a lot to do with the longevity of the tranny.
