DIY: Transmission Oil Change

AlphaSnacks · 01-04-2013, 10:10 PM

Should GL5 fluids really be avoided like someone mentioned? The AmSoil 80W90 in my car is a GL5. And in the cold it is awful up until it warms up. I think I may have ever so slightly grinded 1st just because the gear didn't want to engage at around 1-2MPH (stop sign).

I felt the shift knob vibrate like crazy and I think I heard a very brief noise (my music was up), which I immediately stopped trying to force the gear in and pulled it back to neutral. It just drives me nuts, it's the 2nd time I drove the car since doing the change and the cold weather just doesn't like this Amsoil stuff. The OEM was way better.

But once the Amsoil heats up, it does improve the transmission quite a bit for sure - smoothens things out.
