Hard to Shift when engine is hot

[LetsRolla]

Hello guys,

I have a problem with my AE92, napansin ko mahirap ipasok sa 1st and sa reverse yung kambyo. I experience this only when the engine/tranny is hot. Kapag malamig naman, its a bit ok naman, even better when a bit warm. Its so hard to diagnose since its very intermittent. Its more evident when Im downshifting (2nd to 1st). Is it a transmission problem, a bent fork worn syncro, or clutch problem? Hope someone can help. Thanks!

Pa check mo muna fluid level ng transmission o baka kailangan ng palitan ng bago dahil marumi na . Para mas swabe shifting mo.

Oh sorry, I forgot to mention that, I already replaced the transmission fluids, the old one was like sludge already but no metal parts/shavings seen and already made adjustments to the clutch. Unfortunately, same thing happened.

Anyone had a similar problem?

Kung bagong palit na yung transmission oil, check mo yung clutch fluid. Old and dirty fluid will not perform as needed when hot.

Hi, thanks for replying. Thats the thing sir, I just replaced all liquids, tranny oil, clutch fluid, etc. hoping that it will go away...well, its still there. Im not as knowledgeable in the transmission department so thats why Im having a bit of a problem diagnosing and determining what exactly is wrong

Pag ganyan, ipababa mo na transmission para makita yung loob kung ano ang depekto at nasira. You may contact me at 09393346424 for further assistance.

I forgot to mention, sa start up ng engine mahirap i-shift sa lahat ng gears pati sa reverse, pero pag mainit na ang engine pumapasok na or the moment na pumasok na sa kahit isang gear ay ok na sa lahat gear ang shifting.

Pero me reverse scenario kapang dadaanan, this time pag mainit na ang engine at nasa kalsada ka na at susumpong pa rin ang hardshiting na parang ayaw mo na mag neutral kasi di siya agad papasok sa kahit anung gears na, pero pag pinilit mo ay papasok pa rin naman lalo na mahaba na ang nasa likod mo inaantay ka ng umusad.

The worst scenario ay bigla na lang di na talaga papasok ang gear kung kelan nasa traffic ka.

That happened to me last Dec 25 ng gabi na sarado lahat ng talyer at nasa alanganing lugar pa.

We have the same problem bro, mine is an AE92 also but the "Small body". This has been happening lately lang, but the thing is ma-e-experience ko lang sya sa simula(pagbukas ng engine) as in ang hirap ipasok ng primera tapos kapag magrereverse na ako(Primera at Reverse lang ung napansin ko na mahirap i-kambyo), sumasayad sya (Yung bang para kang nag-kambyo ng di nakatapak sa clutch pedal) pero kapag running na or nainitan na ung makina okay na sya, smooth na ung transmission. I had it checked and nalaman ko butas na pala ung secondary/slave cylinder and wala na halos laman ung clutch fluid reservoir. so I had it repair and filled it up with fluid, mas smooth na ung transmission even on running pero nung na-garahe ko na after an hour at aayusin ko na ung parking nya, sumasabit nanaman ulit ung "Reverse" tho, baka kanina lang and will check ulit bukas.

Check mo ung mga Cyclinders(Master/Slave) baka butas lang.

Update ko lang 'tong post ko. Di na sya mahirap i-shift kahit unang bukas lang. so, the aforementioned solution solved my problem
