Feb 2007 - Isuzu place did transmission fluid flush, dropped the pan replaced the filter and filled with Royal Purple, same was done with all diff fluid etc.

March and April 2007 - VX starts having issues shifting from 1st to 2nd and 2nd to third sometimes staying in neutral for a while and not shifting, simply letting of the gas and waiting seems to help.

April 16 2007 - After reading a thread on here and seeing the same problem with someone whose mechanic forgot to run the trans through the gears when filling up I took the VX back to dealership to check Trans fluid level, they confirmed that there were no leaks however the trans fluid level was one quart low, so they went and got some royal purple and filled it back up.

Now - it is still having problems shifting every once and a while seeming to just get stuck in between gears normally between 1st and 2nd feeling like it is in neutral.

Questions - Does Royal Purple actually make an auto trans fluid that would be perfect for the VX? Could this be the problem? Could the trans being one quart low for almost two months have caused a permanent problem in which I will now have to get the trans rebuilt? Any other ideas? I have never ever ever had any issue with the trans before this I was just trying to make sure to keep the fluids in tip top shape and it cost me over $2k for all the work done in Feb (trans flush, gear fluid, brakes, etc) and now I am having problems with the things I was trying to extend the life of.
