### ⭐⭐⭐⭐⭐ 2006 Infiniti M45. 2 Year Review

### ⭐⭐⭐⭐⭐ little cooler big difference
*by S***Y on September 18, 2015*

I installed this in my 2000 s10 in hopes of prolonging the life of the worn out 4l60e that is in my truck. because i made a mistake i had to install it as a replacement instead of in line with the factory cooler, and it made a world of difference. the engine runs 10 degrees cooler and no longer spikes in temp, and the transmission now takes 20 minutes longer to heat up and start slipping in city traffic. on the highway i dont have any trouble at all with my transmission. tachometer sits right at 2 grand at 70 mph, which is right where it should be. check engine light no longer comes on for a tranny slip code. I know i havent solved my tranny problems completely, but i definitely pushed back an expensive repair shop visit. i can only imagine what this will do to extend the longevity of the replacement transmission. i would most definitely recommend that anyone with an s10 that has an automatic transmission install one of these. although I would go with one size bigger if you do a lot of trailer pulling with your truck
