Hey guys, i'm new to this forum. I just bought a 2000 Prelude (sh?). I don't know for sure if it IS or not an SH because the guy who sold me it said he had the engine replaced. I'm scared i bought it without the ATTS. Here's why i think it IS an SH... 1.)The tranny has M2U4 code on it. (i dunno if the ATTS is atached directly to tranny) 2.)Pearl White paint... i think its available only on the SH? 3.)SH stock rims...5 straight spoke 4.) SH stock Spoiler on trunk.... available only SH right? 5.) Leather wrapped shift knob... no gear numbers on top, i saw some SH's on cardomain with the same shift knob. I can't recall anything else right now... but according to this other post i saw the BEST way to tell is to actually see the ATTS system in the engine or the ATTS light that lights up on top of the gas gauge inside... well... my car doesn't light up any ATTS gauge, and i don't know what the ATTS system looks like inside the engine bay or where it's located, and i also saw some people talking about a ATTS reservoir for fluid.. which they discussed should be ATF (automatic tranny fluid)... well i can't find this reservoir... if anyone know where the ATTS system itself is or any sure ways to tell, please send me pics or let me know? Thanks!
