I've been told by several people that the tranny (automatic) on my vehicle is known for being weak. My new boat/trailer is heavier than the last one, but well under the weight limit. 2 shops have recommended a tranny cooler; another said that, for the same price, flushing & replacing with synthetic fluid would actually be a better choice as it can withstand much higher temps. Each option costs about $225. Until I can save for a sturdier vehicle, which one would be the better option?
