I am experiencing a clunck/sqauwke from my rear end when starting from a complete stop. ask the chevy service rep at my local dealer they said there was a service bulleten out to fix the problem. after looking at my truck they said chevy would not warranty it bc i have 33" tires.http://www.dieselplace.com/forum/smileys/Disapprove.gif So i bought the part myself (Nickle plated slip yoak) just to find out it was the wrong part. parts department said there is no part out for the allison to fix it..http://www.dieselplace.com/forum/smileys/Cry.gif could there be another solution?


Could this be the TSB# 01-04-17-004 or possibly 99-04-21-004A Edited by: CHEVYLUVR
