Transmission check

[nazerath]

where to go for transmission auto check? When I try to accelerate (Almost flooring) from a filter lane to an expressway, it seems to be lagging, like it would rev high then after a second or so get what I want it to do and then start to accelerate. Is this called gear slip?

I do not remember my previous auto being like that it at least not so obvious. Could it be that I am used to the response time of a manual or is the cars transmission giving way?

Is ur accelator by wire or by electrical?

 

Electrical will have a slight lag before the car actually respond.

Most likely it's your torque converter. The fluid pump in the torque converter might be faulty. Slow to fill the drum that would explain the lag in response. There's a transmission workshop above the Ubi tan chong motors showroom. I forgot the name. They have diagnosis equipment to check what's wrong with your transmission.

 

 

Ok, found the company....http://www.sgcarmart.com/directory/merchant.php?MID=14605

Thanks think will bring it down for checking. Fluid pump, is that expensive for Toyota aisin? What price range I should be looking at supposing it is that?

 

The symptoms I describe, what other causes?

For price I dunno.

 

Other causes might be torque converter leaking but that's very rare. Can't be your accelerator or throttle body coz you said the engine manage to rev high rpm thru your right foot input. There's no jerking... So left only the torque converter.

cheapest route first,

 

clean your throttle body, change your atf and filter

[nazerath]

Atf changed but not the filter. Throttle body not washed yet. Could it be the band slipping?

[Furrynadz]

need more info

what car/age/mileage/servicing info..etc

usually 1 atf change is not sufficient, u need 2-3 atf changes to get it really clean, best to do yearly change

 

does the power feel lacking? might be power loss in engine and gb detect not sufficient torque and have to drag more to compensate

 

best to go to a competent mechanic or back to agent / specialist to diagnose

going to a transmission specialist u dont get the whole pciture

Nazerth,

 

My previous auto car had the same symptoms as yours and I had the faulty and worn out gear box replaced with a recon unit for S$3K.

Hoping somebody can guide me with my auto transmission.

 

I have an Estima ACR50 with a CVT transmission. It has had an oil change about 6 weeks ago and drove well for four weeks. It has not started making a noise, the engine revs erratically when in Drive and has caused a sudden stopping 'jolt' (all on different occasions).

 

What might be the cause of the issues?

 

Transmission has done 200,000km.
