Re: transmission slip after driven
I would recommend checking all the new parts installed in the car considering your problem just started after their install. Changing the trans fluid to a full synthetic fluid as well may help, unless the fluid on your dip stick is blackish and burnt in which case it may not be safe to flush. Also while checking, make sure the trans fluid isn't low, if so that will contribute to the slipping. Good luck, hope you get it fixed.
