2004 Buick Regal. Hard tranny shifts.

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.

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.

Hi: re a 2000 lesabre w 86,000 have an auto tranny shifting problem. It's not too bad, but noticing knocks/hard shifts when slowly accelerating from a stop (underload up a grade mostly). Can also be at the...

Sounds like the vacuum modulator on the side of the transmission or the vacuum hose going to the unit. I'm not sure if buick Is fed off of the carburetor vacuum or there's a vacuum tree on the rear of the engine block that may feed it as well. Typically if there is a vacuum leak to the modulator, your engine power will be decreased and your engine will be running rough.

Transmission sometimes shifts hard into next gear.

I would check the transmission and engine mounts but also it may be time for a transmission fluid change. It has a service interval just like oil. 50000 miles
