Royal Purple Syncromax in NP246
I've done some searching and I've seen some issues resolved by running RP Syncromax in their NP246 transfer case in place of the OE Auto Trak II fluid. Have any of you done the same or would you recommend this? BTW, my truck is an '05 z71 with the L33 5.3 and 74K miles. I'm having some issues with the t-case, shifting in and out of 2WD, it's also making noise under 4WD. Thanks in advance.

Anyhow, I ended up getting the Auto Trak II from the dealership and I tracked my issues down to a bad encoder motor / shift shaft bearings. Ordered up the new motor, and hopefully I should be good to go within the next few days.
