Hello people 🙂
I have a question to people that have had issues with gearboxes on the RX300s.
Long story short - ATF change looooong overdue, car started making whining and then grinding noises (gradually louder within a space of a few days). Then one day desperately trying to get to work the transmission went (everything apart from P was like neutral, after engine restart things went back to normal for maybe 60 seconds after which it felt like clutch slip in a manual, then again gone back to normal after restart in a loop until I get it back home 2 miles down the road). Throughout those days the gearbox oil temp was going all the up to the high 80s celsius.
Since then I have dropped the pan, cleaned the magnets (no porcupines but the ATF looked like hot chocolate), changed the filter (mine was already a non-metal filter so didnt attempt cleaning it, just swapped it for a new one), and filled her up with fresh cherry red T-IV.
Now here is where I am confused - car started beautifully, no noises whatsoever, drove absolutely perfect (and smoother than before) for exactly 5 days until today when I can hear the exact same loud whine from the gearbox, mixed in with a slight grind. Also suddenly there is a metallic thud when switching between D and R, and when i pulled the ATF dipstick out after an hour drive, the fluid was brown actually with some bubbles on the stick (level within the hot range though). Transmission running at 65-75 degrees celsius.
Here's the question - is it worth draining and filling her again or send her to a garage straight away (which I'm less willing to do as the bill starts going as soon as they touch the gearbox)?
Sorry for the long post,
Kindest of regards
Kamil
