A/Transmission: Slipping problem at high speed

**Billabong01** · January 4th, 2007 10:05 PM

When I bought this 2nd hand car, it seems it was in good condition. I did checked whatever was the protocol when buying 2nd hand cars. But just recently, when I made a long trip and tried to test the car speeding up to >120kph I felt a strong slipping, meaning the speed suddently slows down while the rpm increases even when the accelerator is pressed hard. When releasing the accelerator, the rpm eventually normalized while the speed dropped down to 80kph.
For those who are familiar with A/T, may I ask whether this is a sign of a serious problem on the A/T. Any suggestion where I can have it checked? How much would it cost me for this?
I would appreciate if I can get a reasonable answer/suggestion on my inquiry.
Thanks and regards,
Bill

sounds like the tranny is starting to "die" ...

**istan** · January 4th, 2007 10:28 PM

so how do we "revive" it?

So tempted to say... "unDIE"

kung kulang ATF, won't the tranny slip when the car is first used in the morning?

generally:

-check atf level... if low or overfilled, adjust to proper level
-if the atf smells "burned", replace with fresh atf.
-if problem still exists, you might want to consider getting a surplus tranny to replace defective tranny in your car.

hindi kaya barado yung a/t filter?

**danesjr** · January 5th, 2007 07:58 AM

tama. try mo muna palitan ng atf at filter.
if problems persists, hanap ka na lang surplus na tranny.

Na-encounter ko sya while constantly running at 120 kph for about 5-10mins with the O/D on. Lower than that I haven't had any problem, even pag galing sa park.

I just noticed over sa max limit yung ATF ko, but the color isn't burnt.
Eto pa, ano ang mas-mura at mas effective overhaul the tranny or palitan sya ng surplus.
