hi i have an '00 ls v8 it has 74,000 miles and the tranny has been acting up. its been shifting hard from 2nd into 3rd and when its in 5th and i give it a little gas i feel something like catching. but when i release the gas you can feel it in the tranny(hard to describe). i dont know, it did the same thing as my 99 mercury sable. but does anyone know how to check the trans fluid? and does anyone have any tips on how to save my tranny? btw my trans is not slipping at all. was going to drop the pan and put new filter and Mobil 1 trans fluid.
