Q: automatic gear box problem

asked by on

good day i have a 2004 daihatsu sirion my problem is when i engage D it takes a second or two to do so (only in drive) also when im driving if i whant to accelarate it feels like it goes in nutral then the gear bangs into place also when i slow down and accelarate lightly . i changed ATF and there was no metal shaving in the oil pan

An issue felt after your transmission’s gear is changed is going to be a problem with the valve body or the valve servos, as it could be binding before gear changed. I recommend having the system scanned and pressure tested by an experienced transmission mechanic.

If you’d like a second opinion on this, consider YourMechanic, as a certified technician can help you diagnose your driving symptoms to confirm my suspicions and suggest an accurate repair. Best of luck.

This sounds like the transfer case isn't completely engaging selected gears (High/Low, 2/4wheel drive). There is a GM Service Bulletin on this issue - TSB Reference #3424. Check with your dealer on this one.
