Power Loss when moving off - CVT gear box
« on: January 09, 2010, 11:14:08 AM »
I've got this problem for the past 6 months. When I stop at the traffic lights for long time(especially in malaysia), once the lights turn green, I feel that the car is moving off using 2nd gear. After which the car will feel sluggish. Another experience was when I was revving the car trying to beat the traffic lights but failed to do so(1.5L not power haha) so had to do hard braking to stop the car. When the lights turned green, I tried to move off, sluggish again. Is it the gear box problem or it's the engine? My car milleage is 65k and is 3 and half years old. I've complain to Tan Chong before when there was still warranty but they say they will retune the engine. Afterwhich the car felt more responsive but I occasionally still get this sluggish move off. Any one experiencing this? Kindly advise. Thanks. Car prices are high now. Dun wish to change car.

Bro,

It like that la.
Mine also the same, bear with it since now car price very high.

Service the gear box on regularly.
To prevent faulty.

Since ur's is more than 60k, have you replace the CVT gear box oil?

Send to TC for checkup? My 2.5 yr old does not have this problem even after stuck in jam for 1hr+ in custom.

Complain alot of times liao. Then they say use Consult to diagnose engine butno fault found. Wat to do? Just pray tat gearbox no problem. Change CVT gearbox is abt $17k as wat TC mentioned unless damn Japan extend S'pore nissan CVT warranty to 10yrs just like in US.

My car now 4.5yrs old & TC say need to do top overhaul (refer to my other thread on top overhaul)

Bro,

I guess the Nissan CVT gear box not so lousy la.
They will not spoilt so fast.
Nissan cvt gear box is better than many brand, eg Mit****shi.
I have hear people driving Mit, complaint the noise from the CVT gear box.

And have fate in Jap technology.
They will not built some thing, that cant last( at least 5 yr).
They very ego about their brand.

So let enjoy our ride.
The lag in power i guess, is part of the CVT technology Hahahhaahha.

But at least you don't feel the car jerk when changing gear.

Regards
Alex

My car has always been serviced by TC. Under their maintenance package they include chang of CVT oil right? They told me they changed it during the 60k servicing. I upgraded the engine oil to Shogun. Thought it was better than Fastflow. However after 5k km engine still become rough again. No choice loh.... Have to wait for new car prices to drop. After warranty stuff seem to give way. Now aircon also not that cold le... After few mins of turing on then the air starts to feel cool. Next servicing must ask them to top up gas.
Cheers

Yes, shd b included in package but not sure in which KM, jus re-checked ur Invoice Bill if they indicated has changed. Mine was udner their NPMP since day 1 oso. :)

I hv upgraded once/pay more for Shogun oil oso, found it sluggish after changed, so immediately switched back to Fastflo on my next servicing, mayb 1 of the reason y u feel lack power.

Aircond compressor, tink still 1 of the main problem in our Latio, I changed mine twice, 1 under warranty, the other 1 paid >1K. Err.. seems like the new Latio all only 60K warranty now? Rem ours was 100K/or 3 yrs. Btw, I hv sold mine last month, rode ~163K. :)

same with mine too, noticeably sluggish after hard braking from high speed, or sometimes going up slope in car parks (especially after a road hump).  sometimes push accelerator all the way, but still the CVT did not adjust "gear ratio".

My guess is that the "gear ratio" software for the CVT got tricked by such situations and so did not optimise the "gear ratio".

Yo.. sold mine back to BM at 30K ~mid Dec 09. Mine was a Sport with SR, reg Jul 05. Rem scrap value ~25K, so got slightly less than 5K for the body. Did checked around with few dealers, at last trade-in with BM since BM is best offer. Btw, me got a New Wish 09 now :)
