Two problems related to transmission shudder have been reported for the 1999 Chevrolet Silverado. The most recently reported issues are listed below.
Since date of purchase, transmission has been vibrating and causing engine to feel like it is under stress/heavy load. Contacted dealer and another chev. Serv. Both advise chev. Knows of problem but does not know what it is or how to correct it. Contacted chev. Cust. Serv. Total waste of time. They do not care. Simply state if chev. Tac says they are working on problem what do I care. They will fix it eventually. Problem is if they dont know what the problem is how can chev. Claim it is not a safety issue. Second problem- abs brakes are activating on dry hard surface at speeds under 40 mph. Dealer syays problem does not exist. Stated they called chev. Tac know nothing about break problems so there must not be one. Tried to say that I dont know how abs works. Have had abs for 15 years know it pretty well. It is definitely activating when is should not. It seems that chev. Is not concerned becasue truck was bought and paid for.
Transmission shifting hard form 1st to 2nd. Dealer replaced transmission assembly. New transmission shifted hard. Dealer reprogrammed truck. One week later, transmission started vibrating in 1st and 2nd gears. Dealer reprogrammed truck again. Now transmission not engaging in first gear untill rpm's are at or above 1500.
