_why is there 2 or 3 different part numbers on Dextron transmission fluid , they all say backwards usable for older cars I Have a 2003 and went to a dealer he gave me 10-9118 he said its conventional and they dont use synthetic except for a special tyanny . so im sorta confused on this why different part numbers and can you use a synthetic in a 2003 V6 type tranny_ ![dextron%20vI](https://global.discourse-cdn.com/cartalk/original/3X/3/d/3d8fd70580ccee2ed9a014a5875b4d88bcf56dfa.jpeg) ---

Hi, the dealer parts man said tht the synthetic is or a HD tranny for very heavy duty usage a in larger V\* trucks or SUV’s. Hes just one parts man out of thousands and I would have to see the stats on that one. ---
