Here in MN, I was quoted $1k to do just the B3 clutch pack from an indy shop that works on German cars only. But from reading some recent post the past year the cost ranges from $600 to 1500 around different parts of the country...kinda wide range but many shops do not like just doing the B3 only and also do not want to under estimate if there is some big issues when it's apart. Mine had all the "classic" symptoms of a worn b3 reverse pack
1. Slow reverse engagement once trans is warmed up. Mine took 3-5 secs for the reverse to kick in.
2.Clicking noise 40% of the time when in reverse. When I had the trans cover off and looked in the front area...pretty obvious why it was clicking.


The parts are pretty straight forward in cost (about $60 for 5 B3 friction disc, $30-50 MB spec seals, $30 7.2 qts AT fluid Dex III($100 if you use MB tranny fluid), $25 at gasket pan and filter). I know this adds cost but I also replaced my speedo cable ($25) and two shifter plastic bushings (2 bucks..and mine was rattling for the past two years and felt sloppy when putting the car into any gear), and front flex disc ($85). All these things kinda add up but are a huge pain to do with the trans still on the car. I did have some laid off worker offer me $400 labor only but after I quizzed him a little.... I didn't trust him. I thought about hiring someone to drop the tranny and reinstall only (got estimates from $300-500 for this only)...and doing the partial overhauling myself. Looking back at it, it would saved me a boat load of time...cause the all the work described on this post took me 2-3 hrs once the tranny was dropped. Dropping took the longest time (whole day 8hrs) and re-install about 5hrs...but this was my first trans job ever too. I learned a ton from this forum and its archives.
