4-matic question

recently purchased a 91 300te 4-matic, and need info on status of 4-matic operation. at start up, lights for 4-matic do not come on, nor do they when car is operating. other dash check lights do come on, though not all. the manual "4-matic funktion" switch in the engine compartment is on the "1" position, so i assume it is engaged. How do i know if it is working? how do i know if the dash light for the 4-matic function is burned out, or non-operational?

87 300TD shifting and acceleration issues

Hi, I'm new to the forum and have enjoyed reading the info posted. I have a 87 300TD with some shifting and acceleration issues. The transmission seems to upshift too rapidly during acceleration and as a result it enters 4th gear by the time I am at about 30 mph. The acceleration from 30 mph on up is very slow. Also, it does not do hills very well at all, even on a minor grade it will only do 45-50 mph and on steep grades it is even worse. Could the turbo be malfunctioning? Is there an easy test for turbo functionality? Could compression account for the problem? On flat roads the car cruises at 80 mph like a champ. Should I get the vacuum tested for the shifting issue?
