My SRX will not autoshift out of first gear when I first start driving it. If I stop, put it in park, then put it back in gear, it usually shifts correctly. It doesn't seem to happen when the SRX is warm. Mechanic said OBD P0989 meant I need to install new silinoid #5 for $1700, but can't guarantee that will fix it. Is that correct? Should I try to service the transmission fluid first?

You should ask the mechanic if he actually directly tested the solenoid and, if so, what the specific test results are. If he did not test the solenoid, look for a new mechanic. Trouble codes can never be relied upon as the sole basis upon which to conclude that a part is faulty. All suspect parts must be individually and directly tested regardless of what a trouble code might "suggest". In the case of this particular code, P0989, as is typical with most trouble codes, there are a multitude of possible causes of the shifting fault specifically listed within the code. All of the potential causes must be tracked down using the specific diagnostic decision tree that General Motors publishes in the Factory Service Manual for your specific year, make and model. Did the mechanic evaluate all of the other potential causes of the Code? If the mechanic cannot explain why he is proposing to replace the solenoid, and cannot explain exactly what has failed, or appears faulty in the solenoid, then you are probably wasting your time and money. Obviously, YourMechanic certified mechanics can diagnose and resolve this issue for you, most importantly giving you an intelligible and credible diagnosis. If you want to go that route, please request a transmission shift diagnostic - solenoids/P0989 and the responding certified mechanic will get this taken care of for you and explain in detail what is going on.
