Default Subaru Impreza slow to engage reverse

Dear All,

Recently about 1 week ago, I realized that when I put to reverse gear, car didn't engage until about 3-4 seconds later. This happens especially in the morning before the engage is warmed up.

Can anyone solved this issue advise how to resolve this issue? Thanks

Best regards,
Jon

Your profile, subject line, nor post contains any model information except "Impreza".
The answer currently is "depends". If you have a CVT transmission and it is cold out yes, it is perfectly normal for delayed engagement for a cold transmission in freezing temperatures. If it is a pre-2012 no - check your fluid level first, then let us know what model Impreza so we can give you information applicable to your car.

Hi

I just checked the transmission fluid is within limits. Wondering what could be the cause? this issue only happens recently.

thanks for any advise

How old is the transmission fluid?
What color is the transmission fluid?
Have you ever had the transmission fluid & filter changed?

Are you going to fill out your profile?

Transmission fluid has been changed only about 1 year ago. Color is pink. Maybe I need to change the filter? as I did not change last time when change fluid.

Sorry what profile, and how do I change?

What brand / type transmission fluid did you use?
Have you checked the fluid level?
- Transmission needs to be HOT for this
I'm wondering if your transmission is slipping a little due to wrong fluid or low level

As far as your profile:
- See the dark blue tool bar near the top?
- See where is says " User CP "?
- Go into that and look at the far left
- Go to "Your Profile"
- Go to "Edit Your Details"

It is probably a worn or defective internal valve or it could be an electronic control solenoid (One that controls fluid flow) that is slow to react in cold temperatures as most solenoids and electronics are. It is somewhat normal for transmissions to act differently in cold temps. The solution is in how you work with such a condition. It of course is something that comes down to how bad is it really? If it is driveable and you can live with it then blame the weather and move on. If you want it fixed, then expect to pay alot of $ and with the high likelyhood of it only being slightly improved if at all. It would be necessary to take it to a transmission specialist or the dealer. Try to let the car warm up as much as possible before driving and keep your foot on the brake for a prolonged period untill the transmission engages, waiting even an extra second or two until after you notice your engine rpm drop. When you do apply the throttle, apply it lightly. Operating the car under these conditions is a somewhat "hightened" version of what should normally be done anyway but it may even allow you to notice more, such as shuttering, noises or other out of the norm symptoms that may indicate a more important concern. OTherwise, rock on

Hi IanT_EJ22 Thanks for your clarification. I will just live with it then, and will do those suggestions you made.

Thanks again!

Color is PINK? Like a frothy, foamy pink? If recently changed it should be a fairly clear red color. Pink froth indicates fluid that is has air. Pink without foam indicates water in it. Check your radiator when it is cold and see if you see if there is an oily residue - you may have a leaking oil cooler in the radiator. Yes, to check fluid level engine should be idling in park. there are cold and hot marks on the dipstick so you can check it cold, but you get a more reliable reading with it hot.
