I've seen some very positive posts regarding Lubegard products.
I'm thinking of using Lubegard Red in my RX330 and LS430 transmissions.
The RX330 randomly has a harsh 2-3 shift, mostly when warm.
The LS430 shifts well (sometimes shifts down and back up when it shouldn't - but that could be an ECU issue) but otherwise 'vibrates' slightly in Drive when stationary (but not in neutral or park, leading me to think this is indeed 'torque converter shudder')
Any harm in throwing some Lubegard red in both of these transmissions on the next spill and fill? Both are currently full of clean Toyota Type T-IV with fresh transmission filters. (Thinking one full bottle for each vehicle, but any opinions on dosage are appreciated)
Mainly looking for a durability boost - fixing the abovementioned problems would be a nice bonus!
