I just can't fix it right

[carlover]

My 1986 560SL will not shift out of second gear by itself, under full acceleration, unless I let off of the accelerator. The rev limiter kicks in so I have to let off, and then it shifts into third. I have adjusted the kick down linkage--no help. It doesn't matter whether I start in second, or kick down into second, it won't shift out by itself under full throttle. Otherwise it shifts fine. ( If I jump on hard from a start, it jumps down to 1st gear and shifts out fine into second, but it won't shift from second by itself until I let off the accelerator some. Any ideas ? NO, I don't normally drive the car that hard, but I want it right so when I do need to push it, it functions properly. Any suggestions will be appreciated.
