hi guys.. have a question... 2004 sierra denali 6.0 awd...when my trucks shifts from 1-2....right after the shift i can feel a double or triple bump or studder.. in fast succesion....somtimes if you hit the throttle just in time right when it shifts you can kinda mask it.... it is more noticable under light to moderate throttle or when under load... under wot throttle it seems to shift fine... the truck has a tune in it.. but the condition was there before the tune .... could this be the trans slipping?....

sent you a pm

hmmmmm.. here is a link... to a custom 170* thermo.. this just might be the ticket.. kinda pricey though.. what do you guys think?... http://www.vincihiperformance.com/LS1%20CO...S%20PARENT.HTML

yeah i checked all those sources... not really sure of the 160* thermo... i think i found soemwhere where the 04 escalade had a 180* thermo.. but i cant find it anymore...

hey guys.. having a hard time finding a 180* thermo for a 2004 dierra denali 6.0.. everything i have found is stock or 160.... is anyone here running a 180 on a 2004 ss? evidently in 2004 they changed something... i think they went to a drop in style from the all in one housing... any help would be great...thanks in advance....rob
