A couple of years ago I made the mistake of test driving a Civic Si and walked away jealous of the amazing stock shifter. I didn’t much like the rest of the car, so I installed a Dieselgeek Sigma 6, metal cable bracket, metal bracket bushings, and a Raceseng Slammer. Before all the upgrades I drained the gearbox and refilled with MTL.
Improved, and nice to use when just driving around, but it still didn’t feel quite right when trying to shift quickly.
Last week I noted that the gearbox felt like it had loosened up quite a bit while the outside ambient temperature was over 100 degrees. After some reading it turns out that MTL is on the heavy side relative to OEM, which doesn’t specify the viscosity.
Great, gonna switch back to OEM.... what’s the part number? Turns out nobody actually knows. I went with G 052 527 A2, however....G 052 171 A2 could also be right, and to make it more confusing there are a number of other G 052 oils available.
I’m a bit surprised at the difference. The most obvious difference is noise, my car makes so much less noise now it’s hard to believe it’s the same car. MTL caused that much noise from the gearbox even with the dual mass flywheel, I can’t imagine what it must sound like to have a single mass flywheel with the same fluid.
Shifting is massively improved as well, it no longer feels like I’m going to break anything when I flick through the gears quickly.
It was expensive, but it’s so much better I can no longer recommend anything else.
