I like redline gear oils. I used them in my SUV and recently changed my manual transmission. I put in MTL when I had about 7,000 miles and put in D4 when I had 70,000. It seemed wrong to put in automatic fluid in my manual but I am happy to report it works well. The effort level with the MTL was not high but it is lower with the D4. I did not expect that. Especially on downshifts, the gears seem to engage easier. We'll see what it's like in 50K-70K miles but I suspect it will still be working well.

I used a cheap harbor freight allen socket on both fluid changes. It is 1/2 drive. I shortened it this time with an angle grinder. I could use it without shortening but it is easier now that it is shorter. I just cut off what wouldn't go into the transmission plugs anyway. Took longer to walk to the shop and get out the grinder than to make the cut.
