Gearbox Transmission fluid?
- Thread starter Ghost
- Start date
Changed mine to MT-LV this weekend. Car has 8,096 miles on it and the magnetic plug was pretty bad. Shifting seems to be a little smoother now.
I've had over a week on the red line MT-LV and I'm very pleased with it, changes when cold are much easier and to be honest I've stopped having to think about changing gear, it just works beautifully.
I was at the dealership for my first BG gdi induction service and asked them to drain and refill with MT-LV while I was there. I was informed by the dealership that it would void my transmission warranty. I thought they were mistaken since it’s an API GL-4 70w oil but I followed up with Hyundai Consumer Affairs and they reiterated that the dealership was correct.
I’m sure it’s an excellent oil, and perfectly fine for our transmission, just relaying the information Hyundai is providing me.
They also indicated a note would be attached to my vin concerning my inquiry (even though I didn’t have them change the oil) so might be time to find a new dealership and have them drain and refill with the Hyundai fluid just to have a record of it.

Yeah, I think it's BS they can even if you may h specs they provide. On the other note, did the BG induction service help??
Yeah I'm in the same boat. I do the CRC intake valve and turbo cleaner every 10k and will do BG at 30k miles
The only time you'll really notice it, is if the engine is really carboned up. It restores fuel mileage and compression lost to carbon deposits on the valve seats. 
Can i have the manual for the eLSD coz our agent plan to replace the oil due to the leak and abnormal sound found.It's very strange that Hyundai offers spare parts and specify the fluid replacement for the Electronic Differential. However, they specifically state in the shop manual not to; service, change, remove or replace the fluid.

eLSD damaged bec of heavy rain/flash flood incident and next day heard grinding noise. so these are the findings after saw the leak below the gearbox as the eLSD is the lowest point (got submerged in water)

serviced the oil,changed Orings, cleans the affected items but the abnormal still there. so have to find 2nd hand eLSD. current eLSD was disabled( hyd pump cable connecter removed) for now.
I’m not sure of the official recommendation but I always do cleaning stuff like this right before an oil change just to be safe.
