When you have it floored sometimes in second when the rpms get over 4000 it will start to slip, otherwise when you floor it, on the 1-2 shift when it hits 2nd the revs will stay up at about 5000 and you can hear a slight whining from the tranny. if any one knows what this is and what it costs to fix i'd really appreciate some info.

 

probably needs a rebuild.... minimum 700 or so, if you get it done the right way with some nice parts and a shift kit, closer to 1500.
