Question about 1988 Oldsmobile Ninety Eight
It also shifts at a high rpm and its a manuel transmission
If it is a manule trans then you need to shift it sooner. And for the reason it will not go into third gear is the gear could be gone or the saycronizer is bad. You will have to put in a new trans or get this one fixed in order to get third gear.

sounds like bad clutches in trans...tranny shop needed...takes 4 qts for a filter change and remember to check it when the vehicle is warm and in park running.

SOURCE: Transmission / RPM
These cars have a lock up torque converter meaning 4 gear going above 35 to 40 MPH, the engine and transmission lock together and turn at the same rate. I know that older GM cars had a plug that needed to be plugged into the transmission for the lock function to work on the torque converter and if you unplugged it the RPM's would run high as you describe. I have never had a 1999 Silhouette and I'm not 100% sure that these cars have that type of plug but it sounds like that type of problem. I agree with you. You know your car and I would take it to a transmission mechanic and describe your problem to them.

Has the transmission been serviced? A transmission oil change and lubricant additive may help, however, it sounds as though you have a 3rd gear synchronizer going bad. Verify the shift linkage is not worn and is secure at the shifter and transmission be for spending any cash. If the linkage is good and the fluid change does not help after 150 miles, you might want to visit your favorite transmission shop.
Good luck and let me know.
