Pga. overføringen av trekkraft til fremhjulene i Automodus skjer ved hjelp av en clutchpakke, skal det brukes AutoTrac olje i transferkasser med Autofunksjon for ikke å brenne lamellene.
The autotrac transfer case has a clutch in it and needs the special GM blue fluid. Originally the Autotrac trucks came with Dexron III ATF like conventional GM transfer cases. However they had a bad habit of clunking so GM issued the blue fluid to fix it. I can get you the part number if you like. The fluid is not very expensive.
I had the clunking problem in my 1999 GMC K1500 with Auotrac. It did not have ATF in it but they said it was something similar based on ATF with additives. The fix was to use the AutoTrac II blue fluid, but first the old fluid had to be completely flushed out by changing it 2x. Some were having problems with dealers and others installing ATF in it because the original AT fluid looked similar to ATF.
