I'm trying to replace the kickdown cable on my'82 300sd. I have the pan and filter off,but I can't see how that thing hooks on there.How do I go about getting the old cable off and putting the new one on?

I know the cable is bad ( fitting all broken up topside ) and it was suffering from not wanting to shift up to 4th and wanting to downshift by itself once it got there.
Also, I slacked off the cablebest it would go, and it would shift up to4th easier, but would still downshift by itself cruising, but if I floored it, it would upshift to 4th and stay there while flooring it.
Should I replace the kickdown solenoid while I'm in there or wait and see what the cable does?

Any help would be greatly appreciated.

Thanks--------Robert
