Downshift = wheels spinning?

So I was wondering why when I've got the car in 3rd or 4th/OD (OD might not be it...whatever it is) and I shift down to 2nd it sounds like my wheels are spinning and burning out? Never had this happen on my newer cars.

As far as I know I've got a 700R4 with unknown gears and an LG4 305.

Well i have no idea what would cause that, but when i got my car, the TV cable was set to tight at idle that when i put it in drive it chirped the tires.

Maybe reset your TV cable?

Theres no way your doing that at normal speeds. Are you downshifting you car at some ridiculous speeds ?

That's possible, he might have bald tires and be driving in the rain for example.

Re: Downshift = wheels spinning?

I only drive my car a couple blocks because it's not inspected. This is at no more then 30mph and probably more like 20 or so. My speedo is off a bit so I"m not sure to be exact. My tires aren't bald and it's not raining.
