I want to install an auxiliary transmission oil cooler in my '07 SXT Nitro with 89k+ miles on it but am unsure just how many tubes would be adequate operating in central Florida where summer time temperatures are around 90+ degrees most of the year. Note, there is little danger of over cooling since we don't get much snow here (heh...heh...heh).
Also, is tandem installation ok or should I consider maybe, a larger cooler (more tubes) and make trans cooling totally independent which should, to my way of thinking, REALLY keep the trans cool? I'm thinking of horror stories with the Nissan Pathfinders where tube in rad crack and allow water to get in the transmission...Not good. Or am I just "tilting at windmills"?
Appreciate any comments/advice.
