A/Transmission: Slipping problem at high speed

[Billabong01]

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]

so how do we "revive" it?
So tempted to say... "unDIE"

[al00399]

Check m muna bro ATF mo baka overfill or kaya nmn kulang.

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]

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

kailan lang ito nangyari?matagal na ba?bago pa ba?sa ilang gear ba sya nagslip?may grabbing ba sya sa tuwing nagshift ka sa drive from park?.

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.

wag ka muna mag jump up sa conclussion,meron pa paraan para di ma overhaul ang trany mo,and besides palagay ko walang prob ang trany mo,ito muna ang gawin mo,ipaadjust mo muna ang transmission band,ang transmission band ang naghohold sa drum to stop from turning para makashift ng mabuti ang mechanism(gear),.kung masyado malaki ang clearance nya, ito ang dahilan kung bakit nagslip sya.ito muna ang unahin mo,then replace replace the fluid filter if there is one.i hope makatulong ito sa prob mo.

Thanks man, you're a genius. That's the same diagnosis from my friend who was a former mechanic from Mitsubishi. My car is now up and running smoothly after my friend fixed it in his shop last weekend.
Man, it should have cost me big time when I brought my car to the Service Center pati yung Servitek (no offense sa kanila pero my friend would agree the same because its business anyway).

buhayin ko lang uli itong thread na ito. kailangan ko lang ng advice.

civic esi 93 yung kotse. automatic transmission siya (PH16 ang makina).

ok naman yung transmission maliban lang sa tercera (3rd gear). nag-slip siya sa 3rd gear. ndi kumakagat kahit anung apak ko sa accelerator.

nangyayari ito mostly pag matagal na umaandar ang kotse sa long trips.

kakapalit ko lang ng atf ilang buwan pa lang nakalipas. DIY ghetto style kaya 6 liters din ang nagamit ko. drain lahat ng lumang atf. hanganng ngayon pink or light red pa din yung atf at ndi naman amoy sunog.

ano kaya problema? kailangan ko na ba mag-ipon pang bili ng surplus?

surplus a/t or surplus engine na lang na manual?

may estimate ba kayo sa cost? tnx!

First check the easy ones, baka throttle cable lang problema at masyado na malaki ang stretch, sabay weak point ang third gear. Good call on replacing ATF. Did you drain the torque converter too? Usually pag nagpalit ng ATF hindi lahat lalabas, dahil nasa torque converter yung matitira.

Good chance na baka kailangan mo na nga maghanap ng surplus, pero check the easy solutions first baka may na-overlook ka lang.

ok. check ko yung cable.

may paraan ba para ma-check at maayos yung "weak point" na 3rd gear? anu ibig sabhin ba pag weak point???

mukhang na-drain ko kahit yung sa torque converter. ginawa ko, disconnect ko yung isang hose then start engine for 5 sec para maalis yung atf th torque converter.

[mbeige]

Wala bang drain plug yung torque converter niyo?

What I mean dun sa weak point is baka at that certain engine speed while in third gear (assuming you have a 4 speed auto?) baka dun yung weak spot niya. It's difficult to diagnose these things without seeing them. Highly suggest you just bring it to a reputable shop you trust.

Ilan ba dapat ang laman na ATF at ilan ang nakuha mo?

[yapoy86]

if you want a DIY, try removing first the oil pan of your transmission then check for the ATF filter inside.. possible its clogged with dirt causing your transmission to starve ATF during highspeed...

if you want to remove the transmission from the engine, make sure you also unbolt your torque converter from the flywheel... the torque converter should stay attached to the transmission when removing it otherwise you will damage the oil seal... (torque converters looks like a pressure plate but sealed)

change tranny filter should help.

[fourtheboys96]

tinanong ko dati dito, sabi wala daw filter ang automatic transmission ng 93 civic esi.

Who ever that is, fired him.

Tranny filter is located inside the fluid pan.
