I am looking for a good gear oil/manual transmission fluid for my 91 MR2 non-turbo (s54 transmission). I currently have Pennzoil Syncromesh in it and it doesn't shift all that smooth, or at least not as smooth as I think it should. The S54 trans is somewhat of an odd topic as ATF (Dex III) is specified for build dates 01/1990-04/1990 and anything later is 75w90 GL4, mine is 02/1990. I don't think it really makes a difference though as internally there are no differences in the build dates to my knowledge.
Redline Superlight Shockproof and Lightweight Shockproof is very popular in the MR2 community, it seems like Redline's more recent MT-LV may be a really good option too, maybe better than the other two. But I have no local dealers of Redline, I know I can order it online but I like to shop local if possible so I can pick it up anytime I need it. I've seen some some Toyota 08885-81007 MT Gear Oil LV (redline MT-LV shows it is directly compatible) in newer manual Toyota's, but it's wildly expensive and I doubt my dealer has it. I have searched locally and can't find any GL4 or MTF/MTL fluids besides the Pennzoil Syncromesh. I'm not sure how I feel about using ATF and its not popular in the MR2 community, maybe for good reason or maybe just peoples desire for boutique oils? I have a local dealer of Schaeffers and I really like their fluids, but I don't think they have anything that would work in this application. I'm curious if there are any other more common choices that I might have overlooked that may work well for my application? I feel like biting the bullet and ordering Redline might be the best choice though.
