Transmission Cooler

[camlex]

Hello,

I was thinking about to add a transmission cooler in my 97 ES300.

A friend of mine, who is good mechanic, told me not to do it. He mentioned that every 15000 miles it drops oil from the plug and you have to refill it. Those coolers are wasting time and money.

Please share your experience.

Thanks

additonal coolers are for extreme heat vehicles

if you tow

or idle in the desert then sure

otherwise it is not needed as you need heat to a point in the tranny
