Hi Scotty...

I have a 97 Dodge ram 1500 my transmission is starting to go bad, sometimes it takes too long to shift, would that be the cause for my car shaking pretty bad ( when I start driving and i get to 45mph my whole car starts shaking, but passing the 45 mark will feel smooth, but when it comes back to 45mph starts shaking bad again, do you thing it has to do with the transmission or bad suspension.. thanks Scotty

knowing those, transmissions, they are rather weak and it is 21 years old, most are gone long before then

Yes the truck its 212000 miles now, do you thi k the transmissi9n ita causing that? Thanks
