when you get on it the car pulls really hard when just in normal drive then it kinda throws itself into second violently it almost feels like it need to throw itself forward to get itself in second or chug itself there when your really on it i recently purchased this car 3 weeks ago. the seller told me it has a rebuilt transmission a couple years back with heavy duty plates and gearing in it. could this be causing it. and im doubting the tranny fluid had been changed in it since it was rebuilt not sure thought, just wondering if you guys have any input on this thanks. and it only shifts this way if your on it normal driving it shifts smooth as butter.
