Hi everyone 👋
I’m looking for some advice regarding a gearbox issue in my Toyota Allion 260 (2008, A18 – ZRT260).
Vehicle History:
I bought the car in 2023. A few months in, I noticed an unusual noise from the gearbox. The car drives normally when first started, but after a few kilometers, the noise appears—especially under higher RPMs and when going uphill.There were no initial pulling power issues, but I did notice occasional jerkiness when accelerating at lower speeds. I got it checked in Pannipitiya, and the technician said the gearbox had been previously repaired. We repaired the gearbox and changed the oil. The noise stopped for a few months but eventually returned. I decided to use the car with noice anyways.
I continued using the car without major issues until recently. Now, there’s a serious problem, sudden loss of pulling power. The car won’t go above 40 -50 km/h even with full throttle, and RPM just climbs. It also struggles badly on hills. If I let the car cool and restart, it works for a short while before the issue returns.
My Questions:
1. Can anyone recommend a reliable place to properly check and diagnose this issue?
2. Since I’ve already repaired the gearbox twice, is it worth trying to repair it again?
3. If I go for a gearbox replacement, are parts available for the A18 model? Can I use a gearbox from the A15 model instead?
Thanks in advance for your support and advice! 🙏
