Gl-5

[chefyong]

Hi,

I was going through the knowledge base of Paragon Products and I came across this for 944 and 968 Transaxles: you use "hypoid transmission oil SAE 75W90 to API Class GL or MIL-L-2105B, or SAE 80 to API Class GL-4 or MIL-L-2105". GL-5 was later recommended for use in all Porsche transmissions through a series of Tech Service Bulletins and FSM updates.

Is this correct that we now could use GL-5 Fluid for the 944 Transaxle?

Could someone who has a copy kindly post this Tech Service Bulletin?

Thanks a lot for your help.
