replaced clutch doesn't hurt the car. THat's not similar as replaced transmission. IF it makes noise during the shifting that cannot be overlooked. I would say if the mechanic says there is no major flaw in the transmission go for it dude. I would say its a steal for 2006 camry with 55000 miles. I sold 2000 camry with 79000 miles and replaced engine for 6000 last year. It was manual aswell and i had replaced the clutch also.
