...from my differential! of course my wallet is $1.5K lighter now...$1K was for the new diff itself, balance was mostly labour.

they replaced it with a remanufactured unit. the tech showed me the old diff and turned the input-shaft by hand and you could hear/feel the grinding. they also did routine trans maintenance, new fluid, cleaned filter/magnet. said he found a fair bit of metal build-up on the magnet and that the trans would likely need to be replaced in the not-too-distant future.

given the trans findings, i should have tried harder to source a salvage unit; this car is not long for my garage...i will probably be moving up my new ride acquisition program from 2010 to 2009.

WTF is up w/ the drive-train on this thing? first the diff and now the trans are going and i've only got 75K miles?

it's GM's GM_4L30-E trans, used in '90s BMW 3- and 5-series for chrissake!
