hi matt,
i just bought a 1993 900 automatic convertible. it would not shift out of 1st gear, but at around 1500 rpm i would here a howl noise like it wanted to shift but wouldn't. i adjusted band and cable and it shifts fine now but it still howls when it shifts into 2nd and 3rd. it only howls when changing gears otherwise it is smooth. it's a howl not a constant whine. i'm trying to explaine the noise, almost like an owl howling, just one howl per shift!!!! hope you have heard of this. i'm writting to you because i always see you on this site, hope you can help.
paul
