Transmission Problem

[StockEngine]

Car Model: toyota avanza 2010 at
problem: ang hirap nia magshift from 1st gear to 2nd. Minsan parang nabubulunan. Then pag ok na at hirap naman sia pag incline ung road. Halos hanggang 60kph lang then nasa 3500-4000 rpm na sia.

Dinala ko sa toyota, ang sabi nila sira na daw ung rear clutch assy. Tama kaya ang diagnosis? Ano ba itsura ng ayos na clutch assy.

San kaya nakakabili ng replacement parts na to?

Eto ung pic nung clutch assy ko sa tingin nio mga sirs, sira na to?

Was the atf fluid changed every 40,000km? Anyways their diagnosis is probably right. At 60kph and the rpm is at 3.5-4k thats like 3rd gear only. Heres a video explaining "clutch packs"
