Replacing a transmission cooler? Chris's rule is about every 5 years in fresh water and every 2 years in salt, and right away if metal or water has gotten into the transmission, since metal stuck between the tubes can't be flushed out. See our heat exchangers and coolers guide, or call (804) 333-3677, Monday through Friday 9 to 3 Eastern, if you're not sure which part you need.
