## Questions & Answers

**Q: Anyone used this for a 3rd gen 4runner?**
A: Yes, works great

**Q: does it fit a 2009 toyota tacoma**
A: Hello T. The 678 rapid-cool transmission cooler does not require any other fittings for it to be mounted for your application.  So yes, it will work for your 2009 Toyota Tacoma. Bert CampRigid Hitch Amazon Sales

**Q: how to install in 2007 nissan altima?**
A: They have hardware to mount it directly to the back of your radiator. You attach it inline between the stock cooler and the transmission.

**Q: Will this impact air condintioning performance?**
A: It has not reduced the A/C cooling ( Miami, FL ) in my 2008 Equinox LTZ AWD 3.4L 6cyl , automatic Transmission Aisin Warner AF 33-5, except to lower the transmission coolant temperature by 20 degrees Fahrenheit while towing a Pop Up  RV camper weighing a bout 2800 lbs. Good product. It will also increase the A/T fluid capacity by about 20 oz., obviously.
