Locked on third gear

[seednie]

At about 60-80kph, when it is about to shift to fourth gear, the gears slip and the rpm just revs at hindi na nag-shift.

what should i do with this?

a mechanic told me that it is stuck to third gear na.........how about your opinion guys?

he's talking about........kung kaya daw dukutin yung sa automatic yun muna bago replace tranny. i don't get what he was saying. BTW my car is galant ss at.

Check your AT fluid level and quality.

Baka makuha ng bagong AT fluid. Otherwise, major repair/replacement work.

[seednie]

just replaced my atf about two months ago.
pero shempre drain lang and hindi napalitan lahat because of those stuck in the torque converter.

[seednie]

Walang sira yung transmission mo, wag kang magpapalet... ang sira ng auto mo eh yung Transmission O/D solenoid valve. Try mo to, turn off engine, then turn on accessory switch sa key tapos press mo yung Overdrive, dapat may maririnig kang clicking noise if you turn it on or off somewhere sa transmission... pag wala hanapin mo yun kasi pag walang kuryente hindi talaga mag shi-shift sa higher gears ang auto mo....

[afrasay]

right.

[seednie]

thanks sir..........gagawin ko yan.
thanks talaga. namomroblema na nga ako saan hahanap ng funds for that tranny replacement.

sir in fixing this kailangan pa din bang ibaba yung transmission?

[seednie]

i have tried it na po.
all the clicking i hear is the switch itself and none on the tranny area.

then i think i should have this replaced. is it inside the tranny?
mga how much kaya aabutin?

[RProject]

nasa labas lang yun ng transmission, hindi kailangan ibaba and transmission mo, usually may single wire lang yun, kasi yung negative eh naka attached na sa body ng auto mo. check mo rin lahat ng fuse mo baka naman putol.
yung solenoid valve ang nag-cocontrol yun ng transmission oil pressure para mag shift. Kaya pag tinangal mo yun, kailangan saluhin mo yung transmission oil or be ready for replacement oil just incase. Maghanap ka ng wire na papunta sa transmission then bilangin mo kung ilan lahat. then hanapin mo yung single wire na may connector socket na male and female (kasi natatangal talaga yun incase 4 repairs). pag nakita mo... ang itsura ng solenoid valve ay mukhang cylinder lang at estimated size ay mga 3 x 5 inches lang. Pero kung may kakilala kang mechanic, ask mo kung ano yung solenoid valve ng auto trans. or kung gusto mo, pa-estimate ka lang kunwari then tanong mo sa mechanico kung saan yung solenoid sa tranny mo...

[seednie]

thanks sir...........
ganun nga ginawa ko. i have it checked sa casa and they used the mut computer they have. may sinasabi silang dudukutin daw. i don't know what they meant about that. pero kasama daw nga yung solenoid valve sa palit. ang labo nga eh. hindi niya ma-specify kung ano talaga gagawin dun sa dukot na sinasabi niya. umalis na ako at napipikon na ako baka dukutin ko pa mata niya eh.......hehehehehe.

[sulzer9]

valve body lang ung dudukutin at ibaba hindi the whole tranny.pero kailangan mo rin bumili ng rebuilding kit para sa valve body.Naka kabit na dun ung 4 pcs solenoid valves pag binaba mo.sana walang diperencya ung end clutch mo(overdrive clutch) at brake band or else baba talaga the whole tranny ass'y.

suggest to check first your overdrive switch system baka dun lang ang problema bago ka mag proceed sa major works.

[seednie]

i had the valve body replaced........minsan ok sha pero minsan nag slip pa rin.

when you are driving and you reached 4th gear, tapos nagmenor ka........when you step on the gas pedal now. nag-rev lang..........you have to wait na mag-downshift back to 3rd gear before umarangkada ulit.

surplus lang pinalit na valve body.
