jumping from first gear

[fastlane]

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?

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.
