This kit from Merchant Automotive will eliminate your woes once and for good. A permanent solution to a growing problem. As these trucks are getting a few years older, the transmission cooler lines can start to develop leaks. This is more common in cold weather as the rubber hose on the line shrinks and allows leaks around the factory

Easy to Set up
Style: 1 to 1 IR Repeater
Works great. Have Sonos playbar mounted behind TV and it does not support eARC, only IR, for use with AppleTV remote. This solved problem.

Works just as advertised!
Style: 1 to 1 IR Repeater
Super east to set up. Haven't had any issues in our very long living room so it must work at around 25ft

Works as advertised with minor aiming quirk
Style: 1 to 1 IR Repeater
Setup was quick and straightforward. I plugged it in, placed the receiver, and it started relaying signals right away. It does exactly what it is supposed to do and successfully extends remote control range to my equipment without any complicated configuration.
The only issue I have noticed is that it can be a little directional. I sometimes have to angle my remote slightly from the left or right instead of pointing straight at the receiver for it to register consistently. It is not a dealbreaker, just something to keep in mind when deciding where to place it.
Overall, it performs its intended function well and is a solid option if you need an IR repeater, especially considering the price and simple setup.

It works!
Style: 1 to 1 IR Repeater
I’ve been wanting to use my DVD player more often, when I work at my desk, but it’s situated too far for the remote. This device works perfectly, now I can enjoy so many old DVDs without having to move or rearrange my whole setup.
