    One thing to add - and I'm not completely sure about the 3rd gens but I assume it's the same - but at those speeds, your transmission has upshifted to 2nd or 3rd, so you really are leaning on the converter hard, just like has been pointed out. The transmission logic doesn't usually command a 2-1 downshift except at full throttle or below 2 or 3 MPH.

    If you manually select gear and put it down to 1st, you will get more RPM to move more air with the fan, and lower load on the transmission meaning less heat. 1st gear on 2nd gens is pretty low; 1st gear on 3rd gens is really low, which will help keep temps down. The only downside is that your throttle inputs will feel more abrupt and can be a little jerky so you have to play nice to keep from giving your passengers whiplash and motion sickness.

    I have not been able to. I would have liked temp and pressure, but nfg so far. Disappointed for sure.

    Any recommendations for a trans cooler upgrade for the Gen 3’s?
