## Description

MT-90 75W90 GL-4 - 12/1QUART

Review: well, not much to say as i feel it smoother on shifting. only downside is the bottle opening. can't really find a right pump for it. i end up just cutting it down to the first top and was able to use a pump that i had. it didn't screw on so i just had to be extra careful not to tip it over. used it in a 2007 carolla s manual transmission that had about 132k miles on it. looks like previous owner never changed it.
Review: Changed out the gl-5 transmission oil that was in my 2006 tacoma to this oil. With the old oil the truck shifted rough and slow, would grind into 3rd gear every shift, felt like a worn synchro. With this new oil the shifts are smooth and it just pops right into the gear. 3rd Gear goes in perfectly 95% of the time, sometimes get some feedback of the synchro when I put it in but its minor compared to before. Would Recommend it for any vehichle especially with brass synchros, but if your owners manual says gl-5 only stick to that. Great oil just pricey might be possible to find it locally for cheaper.
