Intermittent possible transmission problem

[aioshin]

Guys,

Unit Po: Isuzu Hilander 2000 Model
Manual Transmission

Problem encountered:

Tumatakbo pa naman, pero may instance na pag 2nd gear, parang walang power, nag hahigh rev, pero di umususad, till few seconds, kakagat na ang gear, ganun din sa 3rd gear, pag change to it, mabagal masyado mag engage, mag hahigh rev muna din mag normal ang rpm at engage ang gear. Ano kaya posible problem.

Visible problem:

-Merong leak ang slave cylinder nung clutch, pero di naman nauubusan.
-meron din leak yung oil seal between transmission and shaft nung engine.


appreciate any advise.

thanks

Sir baka palitin na ung clutch ng isuzu niyo. Kung hindi pa napapalitan yan since yr 2000.

Yung Clutch disk ko, bagong palit, mga 6 months pa, yung slave cylinder, will DIY replace this weekend. Naisip ko lang, yung oil seal, napalitan na din kaya lang, medyo palpak yata pag salpak ng mekaniko dahil merong konting leak na naman, pero di naman cguro aabot yung leak nun sa clutch disk na pwedeng mag cause ng sliding?. Salamat.

yung leak sa oil seal natatalsikan ng oil yung clutch disc kaya sliding. pag nag high rev ka na-expel yung oil sa disk kaya kumakagat na ulit.

your post does not indicate harsh engagement and does not indicate you have noise.
the only indication on the post is that it slips periodically.
the only thing that comes to mind is the cleanliness and the preparation prior to the clutch disc and the adjoining friction components ( flywheel and pressure plate). given how sloppy most "mechanics" are, the most likely cause was that the friction components were either touched with oily hands or the pressure plate was not rinsed off of the corrosion protective l on the pressure plate.
