'93 90CS Questions for all the experts out there (long)

[Jason A Whyte <Jason.Whyte@dreco.com>]

My car is back from the local dealer after a month of accident related
repairs.  The body work is excellent and virtually undetectable that
there's fresh paint only on the front end.  Put on your thinking caps, I
have more questions for you:

1.  Is there any way of controlling the amount of power assist to the
steering?  My 90's have always had relatively light steering which is
fine in the parking lot, but too light at highway speeds.  Is there any
way of making an adjustment to the system?
2.  My car (72k on it) recently received a tune-up, but it's hesitating
a bit in the mornings when it's cold (here in Houston, cold is 48).  It
clears up in minutes, but there's definitely something wrong.
Suggestions?
3.  The four speed auto transmission seems to lag a bit.  There's a
couple second delay between shifting into a drive or reverse gear and
the transmission actually engaging.  Also, when starting from a stop,
the torque converter seems to have to spin a bit as the engine RPM
increases before you really start to go.  Otherwise, shifting, etc. is
Audi smooth.  Are these just normal characteristics of this
transmission, or could it need some maintenance?  Maybe a transmission
fluid issue?

Thanks in advance for you help.
