My drive indicator on dash is not working and car is trying to start out in 3rd gear 2005 volvo xc90, can I reset the tcm

SOURCE: transmission downshifts erroneously

Sounds like the computer that controls the transmission.....but don't just go buy one because there is a diagnostic route.I just worked on two of those earlier this year,and the computer can drive you crazy.92 is pre OBD 2 or OBD anything,codes are pulled from the car manually.Passenger side interior,front kick panel.Remove the kick panel,locate BLUE colored TWO WIRE connector.It isnt connected to anything.Take a paper clip or wire,bend in a U,insert into connector.Turn the ignition switch on,engine off.This throws the trans computer into self diagnostic mode.Count the number of times...on the dash...the "S" light flashes.This is the code number.Now you look up the code number on a code chart.If there are NO CODES,the "S" light just comes on for 2 seconds when you turn the ignition on,then the "S" light goes back out.Thats normal operation,no codes.If no codes,you are back to square one.Welcome to code diagnostics.Remove paper clip.IF,there are any codes,they must be identified on a code chart,as a diagnostic trouble code for say...the shift solenoids,is a definite solution to this problem.Honda trans's are problematic on solenoids,shift and line pressure.So,check for codes,diagnose any codes and repair them.If no codes,or codes have been repaired,and the same symptom still persists,then it's time to look at the computer,or PCM.The PCM is located either under the carpet on the passenger side front,near the firewall,or under one of the front seats.Remove the PCM,take to a clean bench,and dissasemble.Remove outer cover and look,don't touch,look for a capacitor that may have exploded.I had very similar problems on one....the gear selector indicator would indicate Park and Overdrive....AT THE SAME TIME,when actually in Overdrive,and the car would failsafe to 3rd gear.It was a bad PCM,but did not see an exploded capacitor inside that one.Good Luck...Hondas,gotta love em.

SOURCE: volvo xc90 2004 buzzing in steering wheel, clunck noise under car

that sounds like you are low on power steering fluid ... when the level gets low then the pump starts to ingest air and that produces a buzzing sound when you turn the wheel .....i would add or change the fluid and check for leaks and mechanical loosness in the under car linkages ...you can have that checked at your next oil change .

Testimonial: "Thank you, you were right I took the car in and they said the steering fluid was low. "
