Mobil 1 Synthetic LV ATF HP 19417577 I just had TSB Bulletin 18-NA-355 done on my Camaro and now the shutter is gone and hopefully this is the fix. Wondering for future information the schedule maintenance is to flush the A8 Transmission every 45K but can you go longer with the new fluid? Dealership says 100K but do not have anything in writing from GM to prove it. Does anyone else know if the flush cycle has been extended. I'm asking because the cost jumped to just around $500 to flush with Mobil 1 Synthetic LV ATF HP fluid.
