The problem with the aftermarket is cost vs profit.
Who will buy certain ATFs when the transmissions are filled with "lifetime fluids"? Where's the market???
If you don't want to use the required Pentosin ATF1 or Esso LT71141, then use Pennzoil multivehicle or Redline D4.
Yes, it is technically a "lifetime" ATF. I don't like that fact one bit, either. Shame on all manufacturers who install "sealed" transmissions. A Pox be on their houses!
