Hard shift - weird acceleration vibration
Ok, I'm brand new to Bonnevilles. I just bought a 2001 SE and have been driving it daily. I know I need to fix the clunk in the steering wheel but everything else seemed fine until about 2 days ago. Maybe its just me becoming more sensitive to the car, but I've noticed a weird problem. If I'm accelerating on a straight road the car drives perfectly smoothly. Likewise, as long as I am not accelerating, there is no problem (coasting at any speed on roads straight or bumpy is just fine). However, if I am on a hilly/bumpy road and accelerating, I feel what can only be described as a gear grinding. Its not too loud, but I feel it in the pedal and severity increased with how much the car is bouncing. The best way to describe it is the feeling that you get driving a truck where one is trying to accelerate in a gear that is too low. Its like the gears are working too hard and almost vibrating/grinding. Is this just the car or do I have a problem? Also, what could it be?
My other problem is that my bonneville seems to shift had into and out of park. Every other gear is smooth as silk but park/reverse are a little rough. Not terrible, but I'd like to fix it now if its going to cause problems.
And one last thing- can you save your LIM gaskets if you change to the "good green" antifreeze from DEXCOOL. I'm not leaking yet, but worried...
Thanks in advance.
