i was looking into gettting a shift kit for my 89 aod. i was wondering if i should rebuild my tranny first. it was rebuilt not too long ago about 6k on it right now... and i have stock gears but looking into getting 4.10's what would be the best gears to use with the shift kit...

thanks

 

You should be fine since the tranny is pretty fresh,but make sure you get a good kit and probaly the best kit is from Trans-Go,and the 4.10 is about the best gear to run in a auto fox so you have the right idea so far.
