Secondary Trans Cooler Question
We have a 2014 Forest River Sunseeker 3170DS Class C RV. We just got set up with a Readybrute system to tow our 2013 Jeep Wrangler Unlimited. We took our first trip with the toad 2 weeks ago from NJ...

An auxiliary transmission cooler can never hurt if you're going to tow. Depending on the setup of your coach, it may already have one. All vehicles have a trans cooler that goes through the radiator, which usually isn't enough if you tow. An auxiliary cooler will start around $50 uninstalled, so it won't break the bank. Took me about 30 minutes to install one on my TV. Heat is definitely an automatic's enemy. Instead of a trans temp gauge, consider a smart phone app, combined with an OBDII wireless adapter. Around $20 for both and you'll get additional information such as engine oil temp and lots more. You can also read and reset fault codes if the check engine light comes on. It just needs to be a 1996 or later vehicle to have OBD II.
