Whoa!!! What a difference .... my 3rd gear has smoothed out bigtime!! Amsoil FTW!!!!
Started with 2qts of Amsoil MTF and an inexpensive liquid pump:
Car up on my Dad's
modified ramps (the Civics are too low to drive on the ramps without the 2x6 extensions):
Here is what remained after the change (a little was spilled when the transmission filled and it started to overflow from the fill hole):
This is not that hard to do. The plugs loosened up fairly easy. The fill plug/hole is a little awkward to get to and you end up spilling a little oil here and there - these are the only drawbacks to doing this. If you have an Si, you need to do this if you haven't already!!!!
