- Hello, 2020 Limited CM TRD Off road. I was texting with Mike Sweers, Tacoma/Tundra Chief Engineer about no trans cooler on 19/20 models (they were removed all together). I get TC temps up to 235 and pan up to 225 non towing. Odd because window sticker still says oil/trans cooler w/tow package but every 19/20 has same setup. No trans lines leaving the transmission. The plate between warmer that had two lines to AC Condesor is gone. The warmer now acts a cooler when temps get above coolant fluid temp. They said it still stays 20% below target max tow in testing. Anyone else think 20-25% higher temps in all 19/20 models an issue long term?
