So a while back, I loosened the front band off a 1/2 turn as was suggested. It definitely helped, but did not go away completely. I was not sure how far I could safely go out with that adjustment before I introduce other problems. From what I understand, the front band being too loose can cause a lazy or non existent 1-2 shift. Is this correct?Lazy maybe,but non-existent only when the adjuster falls apart,lol.
I finally got back at this problem this weekend. I dropped the pan, adjusted the bands to factory specs and put it back together with fresh ATF+4. I adjusted the kickdown cable so the lever is almost all the way forward at WOT. I left about 3/16" more pull available. It is no longer a clunk, but It definitely sounds like shift overlap. It now shifts noise free at light throttle and at full throttle but at 1/2 to 3/4 throttle the noise is there.I would adjust it to the max. If part-throttle shifts become too harsh, then the line pressure may need to be reduced. If the car slows down during the 2-3 shift, I would have to say there is something wrong internally.
I will loosen the front band 1/2 turn again this weekend and hopefully I have it handled. What about fluid pressure? Is there any possibility that this could be a fluid pressure problem? Absolutely yes, but perhaps not in the way you might think. I say this cause it is dependent on throttle position. How do I adjust fluid pressure? Can I even adjust it other than with kick down lever? Yes, there is a line-pressure adjuster in the pan. The FSM gives us an adjustment that is supposed to set a proper balance. When you put a shift kit into the VB, then there is always a new line pressure adjustment specified, which the kit supplier has determined will give the best performance with the parts and modifications supplied.
