Trans, Diff, TC, Fluid Change under extended maintenance?

CoralRed335XI · 05-16-2014, 11:28 AM

When do the Transmission, Differential, and Transfer case fluids need to be chnaged? Are these covered under the extended maintenance plan? I'm almost at 100K and want to have it all done if possible...

Thanks!

We changed all of the fluids on our 328xiT at 50,000 miles. 100k is a little late.

At 100k I would:

1) Change the plugs - Amazon
2) Change the transmission fluid and filter (filter - Amazon)
3) Change the oil and filter and use a flushb (Filter Bosch L3307 - Amazon or Ebay)
4) Change the power steering fluid
5) Change the brake fluid
6) Change the coolant and use a flush
7) Change the differential fluid
8) Add Magnet plugs where applicable (Dimple)
9) Change out the belts and pulleys - ECS Tuning has a kit

After that, change all the fluids every 50k. The plugs on an N54 need to changed every 45k. You should probably change out the coils at 125k

If you sign up as a member at Amsoil, you can get 25% off for as many years as you pay for. Amsoil makes every fluid for the N54.

I was able to have those fluids changed under the extended warranty. They replaced the tranny pan too (which houses the tranny filter, all one piece).

Some dealers might not do it since the fluid is "lifetime"... HA! I'm on pretty good terms with mine and it wasn't a problem.
