Kklim Supercharged February 25, 2022 Share February 25, 2022 Been having this intermittent problem with my 12-year-old Sylphy: Gearbox seems to take a longer time to engage when moving off in D mode. Happens only at start of journey after the car has been parked for a while; don't have this problem when moving off at traffic lights in the middle of a journey. Sometimes have to get around it by putting tranny in 2 or 1 mode and then shifting to D. Reverse mode is ok. ATF and filter were changed almost two years ago. What could be causing this? Thanks for any help. ↡ Advertisement 1 Link to post Share on other sites More sharing options...

Thanks for any help. what is the mileage? Order of checking. seems to point to 1st point as it happens only when cold. ATF expands quite a bit when warmed up. 1. check fluid level 2. try to change ATF again 3. overhaul gearbox looks like the solenoids or seals in the valve body. https://www.sundevilauto.com/what-causes-delayed-engagement-in-transmission/ Edited February 25, 2022 by Mkl22 Link to post Share on other sites More sharing options...
Kklim Supercharged February 25, 2022 Author Share February 25, 2022 (edited) Mileage is under 180K km. ATF volume within range. Will check again. Edited February 25, 2022 by Kklim Link to post Share on other sites More sharing options...
Watwheels Supersonic February 25, 2022 Share February 25, 2022 Likely to be the fluid pump that is faulty in the torque converter. FYI cvt gearbox also uses a torque converter. Link to post Share on other sites More sharing options...
Ct3833 Supersonic February 25, 2022 Share February 25, 2022 (edited) there is a possiblity that the trans needs a service, about 2k to 3k, downtime 3 days . go get a transmission specialist shop for assessment, they would be able to tell . Otherwise, this problem may get more and more severe, till the car will not change gear at times till completely unable to drive.

Because my 13 yrs Nissan Latio on cvt some months ago last year its gearbox spoilt and I so I de-registered the car. Initially I heard that afore-mentioned grinding noise from the engine bay area that got sound the faster I drove. Even in N mode the sound was audible but low. Car was serviced on schedule. After a few months the sound became too intrusive and unbearable. Bought the car to workshop for diagnosis and it pin-pointed that it was the cvt gearbox and that the bearings were probable broken. Replacement set (re-conditioned unit from Japan) would cost between $2500 to $3500 estd. Ultimately decided to scrap the veh. Link to post Share on other sites More sharing options...
