Im new to this forum, but have a '00 Neon ES. Bought it new, was the wifes, almost totaled, now mine. Anyway, the car seems to serge back into first gear after the initial shift into second, then back again. Fluid is full, does it hot and cold. I was reading some in here about "speed sensor" codes. Anyone have any ideas? Dodge says it is a tranny going bad and no updates available, said maybe a leaky seal? Thanx

Oh yeah, It seems to do it around 20 mph or 2000 rpm.
