even a chaep U-haul shop can install a "trans cooler" for you, this will exstend trans life exponentially

 

 

while in the shop , have the dealer do a trans re-learn. after fluid change

Anything new in the 6sp hard downshift knowledge?  42000miles and transmission up shifts flawlessly. Has Hard downshift 3to2 or maybe 2to1 or both during quick stops. Should I take it in to at least have it noted before powertrain warranty expires?  
 

Thanks
