Transfer case oil change procedure

[Clark Kent]

I certainly hope it isnt as cosmic as a drain/ refill of the DSG fluid in my Audi. That requires a fairly involved procedure, where a scan tool has to be hooked up and the transmission needs to be within a certain temperature range to accurately service and fill it. Too little or too much fluid is catastrophic.

The ZF 8HP auto is very similar.

lol German engineering… I laugh while mentally calculating the half-life of all the plastic components in the IG’s b58. pretty sure I saw that the IG’s hvac unit was subcontracted to a German firm.

Nearly every modern torque converter auto has a similar procedure for changing the oil. Even the the dealers with the correct tools get it wrong occasionally.

Are you speculating , or do you know about modern plastics (derived from Ineos chemicals )?
Plastics made in 2025 are not the same as those made in the 70s/80s (though plastic parts in my 70s/80s Porsches are still absolutely fine)

BMW engine plastics failing is a well known weak point.

I'll just quote a random guy off a BMW forum
"Show me examples where plastics are problematic…… I can tell you that the N55 has two plastic items that are problematic. The turbo intel pipe and the charge pipe.

Most of the other plastics in the N55/B58 as long as the car is cared for and the coolant is replaced at the appropriate intervals, there are no issues with the plastic items in the cooling system.

Valve cover leaking is not due to the material of the cover, but the actual gasket. Gaskets have never lasted forever, before plastics. Just like some claim plastic warps so does metals. Dissimilar metals expand at different rates and plastic is possibly the best metarial to have.

I can tell none of you complaining about plastics have a clue about material science or even come close to having a degree in the field of engineering"
