Been running Mobile 1 since nearly day one. Just purchased some Redline 75w90 GL-4 for the trans. Need to install it. I just put the Redline in my Suzuki and it shifts very nicely.

The MT90 is a great improvement for shifting . No clunk into reverse , notchiness or grinding . Would not advise a GL-5 for any Toyota manual tranny . Tried a MOBIL1 gear oil all the issues described and got worse . Drained it and put in the MT90 . Problems gone .
