2004 Buick Regal- Hard transmission shifts When accelerating the tranny shifts hard at 10 mph and then again at about 20mph. Also when accelerating, the tranny seems to spin without getting a grip. then it shifts and goes. It's like you're trying to run but your feet are slipping. there is no high pitched whine.
Try some Lucas Transmission fix. that stuff has done wonders for almost all of my tranny problems
I have researched this issue for hours online. Almost everyone gave the same answer. Here goes: You can try to install transgo shift kit. It usually always fixes harsh shifting issues and it is the cheapest and easiest solution. I would definitely try this before any other solutions. Plus there are videos on the internet to install it yourself. Good luck.
