where to get this conditioner?? i have the exact same issue, even though i changed ATF to correct spec and ATF is also fully synthetic and fan and thermostat are automatic but occasionally it happens on cold or rainy days
mine is also a three speed automatic, it stays lock in third gear and extremely slow to accerate until after some time when it warms up and automatically starts shifting,sometime happens regardless of hot or cold start but with low ambient temp
the lever goes into D easily but it would start in third gear, if you put in L then first gear always engages, however putting it in 2 again doesnt work, when this issue is there sometime theres a bit of jerk while putting in D but not in R, other times when its fine theres no jerk at all while moving to or from D and it shifts perfectly.
