904 slow shifting into high gear????? Help plz!

good point strokerscamp no kickdown linkage,missed that one, I kinda know what your saying about the convertor,but I`ve not seen one only have a problem on the 2-3 upshift,I guess once it goes into 3rd its ok,it just sounds like it has a delayed shift,or did I miss that too? if it is a delayed shift,and we know the trans was air tested on the bench,cause everyone does that,right,no major leaks from the front clutch seals,than it could still be a front band adjust,I talked to Paul at T/A a few years back on a similar issue,it had the full manual forward pattern and it had a 2-3 flair up of about 600 rpms,he discussed how I was adjusting the bands,I said same way I`ve done them for the last 25 yrs,long story short he got me to tighten the front band adjustment more than I like to... and it took 300 rpms of that flair out of the shift,I didn`t dare go any tighter,didn`t want the band to drag,but remember that was a forward pattern,I mean it could be in the convertor,but do you concur we should check the seals and band adjustment first?Scot.
