Hey guys I'm new to the forum, been visiting it for quite a while now lots of good info on here.
Having a weird problem with my 85 250es. I just bought a complete used engine for a good price and dropped it in as the original was clapped out. The engine runs the very best, no smoke at all, and the clutch grabs well and the shifter feels like it should, but the transmission is doing something very strange. It started out doing it only in 1st gear, but after several miles has moved into doing it in 2nd and 3rd gear now too (once you get up into 4th and 5th it runs along just fine). So what's happening is it sounds like it's between two gears when you go to take off from idle. You can hear a gear grinding noise coming from the right side cover. Once you get rolling, it starts to go away. Let off the throttle and hit decel then back on the throttle, it'll do it again. The rear end is in good shape I thought maybe it was skipping back there but it's 100% an issue in the clutch side of the engine. There is fairly new looking gasket maker on the right side cover, so someone had been into it in the last while. I'm wondering if maybe something is out of adjustment or if they put something together wrong. Anyone ever experience this?
Thanks
