Clunking intermittently when turning the gear oil wasn’t red but black silver lookingI couldn't tell from the picture if that was just globs of old gear oil. Chunks of metal would be a bad thing. Do you hear any unusual sounds from the gear box? Do you feel any weird "grabs" or "releases" while driving under power at a steady and slow rate?
Well, you know where those chunks of metal came from then, damaged gear teeth.Yes grabs and releases definitely
Yes oil the oil was drainedWell, you know where those chunks of metal came from then, damaged gear teeth.
Can't say as to the cause, but unless you cleaned up that plug before taking a picture? Did about 1.5 L of gear oil come out when you removed the plug?
The oil was a silver dark colourYes oil the oil was drained
That's not good news, usually it's just a dark, transparent color. It means this oil has collected a lot of metal grindings and chunks. Have you owned the EV the entire time or was it bought used from someone else?The oil was a silver dark colour

2 years ago I’ve done 20k in it stop start running I’m a courier driverIt was bought used
The van is a ex cat d repairedUnless you are driving like the Fast and Furious movies, it's possible that a lot of things could have happened but it would be hard to pin down. Wrong gear oil, no gear oil, contaminant in the oil (water, dirt, etc.), manufacturing flaw in the gears itself, vehicle accident, etc.
I’m thinking of changing the gearbox but the one im looking at is from a 2021 leafThe van is a ex cat d repaired
Not good!What do people think to this
Sort of, kinda, maybe.Will a leaf gearbox 2021 fit a 2016 env200 van
I've been doing oil changes in various engines for over 50 years and have never seen anything that bad. I replaced the reduction gear oil with synthetic in my 2015 leaf at 50,000 miles and there was just a thin film of particulate on the plug magnet. It's a miracle that your gearbox hasn't seized up. It must be that the gearbox vent somehow sucked in some water. The only other things I can think of would be sabotage or a grossly defective gear.What do people think to this
