Usually indicates that you have a TCU (transmission control unit) problem. Take the car to a transmission shop and have them run a diagnostic on the tranmission and TCU. TCU usually runs around $150 to replace but you can sometimes find them cheaper at a local junkyard.
Transmission problems (?)
It can only mean one thing "Check your engine"
I guess you mean the Autobahn. You just drive on it, like you drive on a Highway.
There is aproblem with either the transmission or the overdive unit.
letters don't specifically have a definition. 'H' means 'H'. if you mean when you drive on a highway and you see a sign that says 'H' it means hospital.
Transmission has a problem. Take it to a professional.
If by this you mean only "hot heat" when drive at highway speeds likely thermostat bad and/or almost stuck and takes long time warm up from high engine RPM during highway driving.
speed control sensor is bad
You do not specify what this red lamp looks like but redmeans STOP, so it is either the oil pressure light or coolant temperature.
32 and 2132 and 21
It usually means your transmission is going bad. Is there a code (Check engine light on) with the flashing light?
