hello, at one time race car would shoot fluid out dipstick tube when shut off. was never able to fix, converter, valve body change etc. cracked case ??? heat sink cooler mounted on firewall above tranny air bond??? ended up changing tranny
Would have more questions but since the trans has been replaced I guess all we could do now is guess.
Best guess, a real rapid increase in heat buildup after shutdown expelling fluid out. Why? Dunno.
