rebuild kit = reputable vendor like triple edge performance seems to me you have horrible luck with transmissions and used transmission from a yard is the last place id take my chances......
spend the money on a trans from a welll respected vendor the rest on these cars are cake.
Id put my risk in a used engine over used trans everyday.
Speakin of im currently looking for another 2 door shell engine and trans dont have to work my 2 door got T boned today
Ive been down your road lol clean body and trans after that its cake.
