ED wheel spinning.

[kpcart]

Hi i just noticed in the wet, the car spins the rear wheel too often.
Im wondering if my diff was changed by previous owner, but i doubt it because it gets to 80kmh in first (auto) just like factory spec.

But although wheel spin is fun, its a bit annoying, i cant do fast overtake in the wet, or if i do it has to be gentle acceleration, if i floor it at 60, goes to 3rd or 2nd, and then kicks violently into 2nd or 1st, and almost throws the car off the road by giving a hard quick wheel spin on rear wheels, i nearly had a heart attack first time i did that. at lights, every car can get away faster then me without wheel spinning! (still in wet im talking about). i have to take off like a granny.
Maybe the accelerator cable is too tight?

Also is it normal to be able to do stand still burnouts on a dry road. i dont seem to have to give much gas while holding brakes and it spins rear wheels. thats kinda fun, but is it typical? does it spin at the torque convertor stall point (forgive me, i dont have much knowledge of how torque convertor works)
i assume if i do that too many times, it might damage, gearbox, torque convertor, brakes or something else.

Running gas, this is still the case, but a bit less wheel spin now. do the newer fords and commodores get away from lights in the wet much smoother faster then me, and without any wheel spin because they have traction control.
