I didn't know anyone wanted the tsb number as I have already had it done. The mechanic told me I need to put a couple of hundred miles on it to notice all the changes. He agreed the last one only worked for a short time and than the same problems started over,sluggish,jerking on take off, etc. It did seem better when I drove home but that was only 10 miles. Don't know if it will help the transmission shifting and downshifting when stopping cause I think it has it's own tune.. Sorry about the TSB. number.
