[ROVERNET - UK] 3500s auto transmission shifting

Hi All,

I recently replaced my 3500s transmission (automatic), and this  
weekend, spent some time adjusting the kick-down cable to work  
properly. After reviewing the shop manual, It appears the cable is not  
original spec, (or the crimped stop on the cable is missing) so the  
procedure for measuring the adjustment does not hold up. I've got it  
adjusted so it works well now, shifting down when the accelerator is  
put to the floor, and at the correct speeds.

It seems as though the light throttle shifting occurs at higher speeds  
than it should--20+ mph for first to second, and 30+ for second to  
third. The full throttle shifting is in the correct range, 30+ for  
first to second, 50+ for second to third. And the maximum throttle  
shift changes seem to be at ok speeds.

But on maximum throttle from start, I get what I think might be a  
clutch "squeal" at gear shift intervals. This only happens if I keep  
the pedal to the floor through all gears. The book describes this  
squeal, but says nothing about what to do about it. (The first thing I  
need to do is check my belt tension to be sure that's not the squeal  
I'm hearing...)

It also seems to shift a bit "harder", not as smoothly as when the  
cable was improperly adjusted. When the cable was loose, I had no kick  
down at all, but the gear changes from start were smoother.

The book says NOT TO adjust the kick-down cable to change fluid  
pressure/gear change speed, but how else would this be adjusted?

Any thoughts?
