really depends.....
depends on if the shop is any good or not too.... there are a lot of shops that rebuild stuff cheap, but aren't worth a piss.....
when my w55 went out, i was told by a few tranny shops they wouldn't rebuild my manual tranny, but would find me a good transmission pulled from a vehicle..... i didn't like that.... eventually i found a used one on here from a member a lot less than what the shops wanted.... i was quoted about $700 for a used, not rebuilt tranny from more than 1 tranny shop.... they actually all said there was no $ in rebuilding it for them, automatics is where tranny shops make $
