my transmission has been slipping pretty bad for awhile so i finally broke down and got a different one....
my question is what fluid should i use? synthetic or regular... its a used trans but only has 28000 on it....

Synthetic usually is not good in these tranny's. It tends to make them slip even worse. Just stick with factory fluid, or if you want the best stuff, get the new dexron VI fluid. It's a little more expensive than dexron IV though.
