These are the recommended AT fluids for my Chevy Aveo. I'd rather use a more readily available brand but am not knowledgable about cross-referencing.
Anyone here absolutely know for sure a good alternative?
If you go to Castrol Australian web site, go to Lube Reference Guide, they suggest my BMW 740i(with 5hp30 trans filled with Esso LT 71141) to use CASTROL TRANSMAX Z.
Also from this web, they quote
"Check transmission colour coded label for specific transmission lubricant recommendation. THMR1 transmission with Black or green sticker, use CASTROL TQ DEXRON III; 5HP-18 transmission with Black sticker, use CASTROL TQ DEXRON III; 5HP-18/24/30 with Green sticker, use CASTROL TRANSMAX Z; 5HP-30 with Black sticker, use Shell LA2634; GM4/5 transmissions with Green sticker, use ETL7045."
Two common replacement are Redlline-D4 ATF and Pennzoil or Quaker State "Multi-Vehicle ATF." Redline is synthetic and both Pennzoil and Quaker State are semi-synthetic. I've used both in my BMW with good results.
