R607T Pyro (non-EV series) #ad




R5659R EV (says oil temp, not trans oil temp on mine) May be a different P/N, but you get the idea. #ad

Check out the pictures posted by bmoeller! You can see the reflections in the EV series versus the others. Some people, me included, have found this to be objectionable. Your opinion or choice, but be aware!

Other than that , mine have been great!!!
