Winter is here… Now’s the time to plan the upgrades for the spring.
Fluids perform at their best when they are fresh, clean, and cool. The synthetic swap is a debate I’ll leave for the bitog forum gurus. Of course the next step is to keep them cool. ATRA (auto trans rebuilders association) released research showing every 20°F drop in fluid temp doubles its life span.
So where to start? Transmission cooler is my suggestion. Transmission repairs are costly and can be a nightmare if the problem is misdiagnosed or something else is missed.
So if you start looking around there are a ton of choices out there for transmission coolers. So who do you choose? And why? For starters I wanted a cooler from a manufacturer, not some parts importer. Manufacturers that have their name on the cooler have more skin in the game. Next I look for the age of the company. Appears Hayden has been in the game the longest… and they have a bad ass plate fin cooler at O’Reilly Auto. Sold.
Scan tool shows 170°F trans temp after some spirited driving (within the speed limit on the frontage road of course).
Next up, engine oil cooler.
