zuke is A1 correcto.
just on the input , sounds like a tune up as misfire is always , violent.
tuneup , with filters , all. (cap,rotor,wires,plugs,filiters. fluids)
then if it goes away , you are off cheap.
if RPM's (engine speed) rise fast and you cant go faster ,then the tranny is bad.
Slush pump diagnosis
one guy here , his car would go slow in turns. tranny slip.
if it is slip , its killing the trans.
if you have full fluid levels and it slips the bands are burning up.
do not drive a slipping transmision, unless you are rich.
