I used Mobil 1 75w-90 in my Toyota (not Lexus) instead of 75w-85. It is was recommended by a Toyota dealer. And it is what I am going to use in my LS460 when I get to it. If you don't mind paying extra, you can get Toyota 75w-85. I have no experience with Redline products.
I am going to call my local Lexus dealer and ask what they use, when get some time...

From my 2014 owners manual:
Front: Toyota Genuine Differential Gear Oil 75W-85 GL-5 LT or equivalent (0.79 qt / 0.75 liter)
Rear: Toyota Genuine Differential Gear Oil 75W-85 GL-5 LX or equivalent (1.42 qt / 1.35 liter): very hard to find and pricey too!
Transfer case: Toyota Genuine Transfer Gear Oil LL80 or equivalent (0.74 qt / 0.7 liter)
Automatic transmission: Toyota Genuine ATF WS (11.3 qt / 10.7 liter)
Looks like Redline 75W-85 will substitute for both LT and LX. But there is no substitute for LL80, which must be purchased through Lexus.

I got the differential, transfer case, and ATF services done at my Lexus dealership last month. I went with their standard Mobil1 fluid for the differentials (probably 75W-90), and I bought them a can of LL80 for the transfer case. They use ATF WS for transmission. My car was running smoothly before, with a slight vibration felt in the shifter sometimes. I have not seen an appreciable improvement but I haven't driven nearly enough since to make a stronger judgement. Overall, I am happy I got the drain-and-fill service done. 80,000 miles on my car.

Thanks, I appreciate the info, I'll double check my manual as well, I think it may be important to use the LX in the rear of mine and the LL80 for the transfer case given that I have AWD. I called lexus and they were very unhelpful.
