jumping from first gear

**fastlane** · May 28th, 2007 03:15 AM

Hello to everyone. I need help with my car's transmission. Kumakalas yung first gear niya. All the other gears are fine. Pinababa ko yung transmission ko dahil sabi ng mechanic ay baka yung "synchronizer" daw ang may problema. Nang mabaklas na yung transmission ay nakita namin na ok pa naman lahat ng mga synchronizers at mga ngipin ng gears. I got a second opinion from another mechanic and ganon din ang sabi na wala raw problema sa synchronizers. Since nakababa na rin lang yung transmission at medyo marami na ring mileage yung kotse ko ay pinapalitan ko na lang lahat ng parts sa loob ng transmission ng japan surplus (cost me 3K) hoping that the problem will be fixed pero kumakalas pa rin siya sa first gear. Ano kaya problema ng transmission ko? Help.

Anong kumakalas? It pops out of first gear? Might be a bent shift-fork (although not knowing your vehicle, I can't say for sure).

Sayang yun... if nothing was wrong with your gears or synchros, you shouldn't have swapped them out.

What car?

Worn clutch maybe? :confused:

Hmmm had a problem a month ago na with this din. Baka maluwag na ung gearbox mo kaya di na kumakagat

How was your problem fixed? Did you replace your gearbox? Kailangan ko na kayang palitan yung bung transmission ko? Nagcanvas na rin ako sa Banawe. Mga 6K yung Japan Surplus. Any other ideas? Thank you.

Sounds like a damaged 1st gear. You will need to replace the 1/2 gear.

I had a similar problem where the manual tranny will not stay in 3rd gear. They replaced the 3/4 gear. This will require the tranny to be pulled down and openned up if you opt to replace the broken gear. The alternative is to get a surplus tranny and swap that in.

Thanks for the advise. My car is a Nissan Sentra LEC 98 model. 90K na yung mileage niya. Pag nag shift ako sa first gear at nagbigay ng gas, nag-jujump yung gear to neutral. Pero pag hinahawakan ko yung shift knob ay napipigilan naman siya. Wala rin daw tama yung shift fork according sa mechanic.
