Going to dump the trans fluid in the MR2 this weekend in addition to doing the front ball joints.
Anyone used the NAPA Sta-Lube Gl4 gear oil before? https://www.napaonline.com/en/p/SLRSL24239
I ordered a gallon and I'm going to use it. This transmission has yellow metals and all over the forums you can find people saying to avoid the GL5 fluids for this reason and because they degrade the shift quality.
I know everyone is going to say to use MT90 or MTL or Lightweight Shockproof (Smurfs Blood) and while I have used all of these before, I'm doing something different this time.
This GL4 fluid should be fine for my use (a manual trans that specs basically everything from GL3 to GL5/MT1 and even came factory filled with ATF in 1990-1992) but I have not seen anyone use it in a transmission aside from a few Miata people who say it shifts great.
Anyone used this before, specifically in a transmission, not differential.
