Rebuilt A/T hesitates to upshift

**ParticleX** · April 19th, 2014 06:37 PM

Good day,

We had our Terrano's trans rebuilt (new rebuild kit and new strainer). Sliding sa 2nd gear kasi before and there are times na ayaw talaga mag shift from 1st.

The vehicle is then delivered to ours ng aming trusted guy (charged to fleet card kasi so sya ang nag negotiate and nagdala sa shop). Tinest ko kaagad uphill dito samin, meron dito mga 200 meters of a steep slope na hirap dati nung sliding pa, nung time na yun medyo satisifed na ako

A day after it was delivered, I've driven the vehicle again. after a few minutes of warm up, umalis na ako. I noticed violent vibrations pag upshift to 2nd or 3rd gear. After a few minutes (presuming operating temp na makina), nagiging OK na shifting from 1-4 pero there are times na inconsistent pa rin and ayaw pumasok. Minsan pag binibitawan ko silinyador, parang nagdidisengage sya from its current gear (parang nagne-neutral ba)

So sinabi ko yun sa guy namin. Sabi nya eh nung pagdala nya daw from shop papuntang bahay eh oks naman. According to the shop, observe daw for 1 month kasi hindi pa daw "lapat" yung mga seals and linings - halos pudpod na daw ang lining and other parts accdg to our guy.

For two weeks nagtiis ako sa violent vibrations for a few minutes pag umaalis ako. After a few KMs umookey na shifting pero di pa rin ako confident. Ngayon eh na lessen onti vibrations pero it is stil there. Medyo nag improve naman compared to the first few days when it was delivered

My question is kung may madadamage ba if sige ko i drive despite the upshift problems? Will changing the ATF improve it? Red ang atf and adequate ang level. Nung sliding pa kasi eh wala naman akong naexperience na vibrations except i have to rev higher para mag upshift. 6 months warranty accdg to the shop.

Thanks

there's no such thing as hindi pa lapat mga seals and linings sa newly rebuilt tranny. may problema yan kaya may vibrations, pag patuloy mo gamitin ay malamang masunog uli ang mga clutches. so mas mabuti ibalik mo na sa gumawa habang maaga pa.

...That was the one I'm thinking, na dapat after rebuild eh oks na dapat, kasi madami akong nababasa na after rebuild there are no problems after.

Hindi kaya the A/T TCM (Transmission Control Module) eh nag re-readjust pa sa shifting patterns? May Hold, Normal, and Power button kasi yung sakin. Pag nagvivibrate, ilipat ko lang either sa Hold or Power, umookey na, pag binalik ko sa Normal andun yung hesitation to upshift. Baka kasi 'nasanay' nung sliding trans pa, kelangan i-reset

May nababasa rin ako na after a week or two, the ATF should be replaced on the rebuilt tranny. Eto muna gawin ko. If this doesn't fix it, ipadala ko na sa transmission shop. Nasa Rey's pa kasi to have the electrical system checked.

Thanks

This is way I hate rebuilt trannys. Kung swertehin 6 months tatagal. I just buy surplus, less hassle and warranty is palit lagi. Hehe

Anyway, tama no such thing as Hindi lalapat seals. Pagbuo, game na yan. Better bring it back before it causes anymore damage.

how does one determine if a surplus tranny is still formidable considering it's been also used for so many years by the previous owner?

mas mura ba bumili ng surplus tranny kesa sa magpa-rebuild or overhaul ng tranny?

As much as I've wanted to, sagot kasi to fleet card (read: libre

) kaya I grabbed it na lang.

Sige, after an ATF chamge prolly next week, if hindi pa nagbago definitely papababalik ko ito sa shop.

Mas mura magparebuild ng tranny pero may chance na panget gawa... Bili ulit.

No one can determine the condition of a surplus but it's better since less than half a day takbo na ulit. They give warranties of one month. Much better in my opinion.

In my experience kasi, mas tumatagal yung surplus since Hindi PA nagagalaw yung loob.

Hindi kasi ako chief yung nakipagtransact with the gas station's manager. Saka kelangan approved shop nila or kelangan magusap yung manager and owner of the shop bago i accept yung job order. Somewhere in Paranaque yung shop, don't even know the name

Pero sabi ng shop if problems persist, bubuksan talaga nila ulit. Di rin naman ako papayag na di nila maayos yun hehe, medyo mas maayos pa nung sliding kasi all I have to do to is rev higher para mag upshift from 1st to 3rd gear.

Nasa Rey's Electrical pa kasi to have it rewired (alam mo naman when they convert, sh!tty ang splicing and reconnecting ng wires). Check ko na lang if may improvement ang rewiring and an ATF change.

changing the atf of a newly rebuilt trans won't do any good. sa mga dapat magpa rebuild ng tranny siguraduhin nyo may scanner ang shop and dapat kasama sa diagnosis ang pag scan muna bago katayin ang trans. example kung ang naging dahilan ng pagkasira ng trans ay dahil sa electrical issues so pag ka rebuild at hindi na analyze mabuti ay siguradong mauulit lang ang problema.
