watup, need info on pops CRV

watup fellaz/ladies. i'm from vegas, and a dsmr, but figure that someone here might have the info i need.

my pops has a CRV, and i do all the work on it since im handy with the tools. he was tellin me that he thinks his auto tranny is goin out on him. he only has 30k miles on it, and no performance upgrades.

are there any auto tranny buffs in the forum that could help us out.
i am wondering if the auto trannys are prone to early failure, and if a tranny fluid cooler would be beneficial.

thanks for the help and the space.
