I did some searching around and still haven't found a solid answer. The gst doesn't seem to like to downshift into third. If I'm out driving and I go to drop into third from fourth, it's like I hit a wall. If I wait a second before I try and slip it into third...it'll go ever time. I originally thought it was due to the pos short shifter that the previous owner had installed(huge piece of shit ). However, I just installed my new b&m short shifter and I still have problems downshifting from time to time. Keep in mind that the only gear I have trouble with is third.
The next thing I'm gonna try is having the tranny fluid changed. Any other thoughts...and I don't wanna hear about anything expensive ...I've spent too much on this car recently
