Downshift whine after transmission service
Hi Guys,
I took my ISF to get the Transmission filter change and oil top up, after the service i noticed that when the car shifts down it whines, the dealer says this noise is not related to the fluid change as i took the car straight back again to recheck the level, does anyone else have noise like this ? please see video with whine sound after the click from the paddle shift, i have a meeting tomorrow with the shop foreman but during the phone call today they claim something is wrong inside the transmission
car has 193k KM just under 120k Miles, driven almost 30k KM in the last year without any whining noises
TIA

The transmission oil pump at the front of the gearbox whines more when the level is too low. AMHIK.

If you took it back and they checked it hot then it wasn't done properly.
The service manual specifies the fluid temp should be between 95F-108F (35-42C) for proper fluid level check/adjustment. That means typically the car needs to sit at least overnight for the fluid to dissipate all the heat. It's always easier to do in the winter time since the fluid takes longer to heat up thus giving you more time to work

I took it back on the saturday morning (picked up on friday) and they looked at it yesterday, they said they checked the oil level again and the noise was slightly better but then they said the noise is not related to the oil service but to some damaged part inside the transmission, but the car never had any noises before, im waiting for a call from the shop manager today

It’s absurd stuff like this that keeps me working on my own cars. Lexus should know how to do this.
