## Questions & Answers

**Q: Does this kit hook right up to both the input and output cooler lines on from the transmission if you’re doing a complete bypass?**
A: No, you would have to buy to kits as you would need two female fittings.

**Q: Is there any way to get two males instead of one of each?**
A: Only the seller can answer this question

**Q: Are these the push on style that do not require hose clamps?  Also, what size hose is recommended?**
A: They are barbed and require clamps. The hose size is 3/8" i.d.. Also, these fittings don't fit a 2008 Chevy Tahoe, which require a straight fitting with o-ring.

**Q: Will these fit a trans cooler on a 2005 3500 Silverado with a duramax and Allison transmission?**
A: Our vendor answered .............  Our 390 will not for a 2005 Silverado 3500 transmission cooler.
