Is anybody running a 4r100 suncoast transmission with extreme towing
package? If so, how is the performance?

The best. I towed a tank of a 5th wheel, a tripple axle Carriage 40' beat for 5 years with mine. I had the DP Tuner with the 50hp tow setting. What a great combo. If you tow, you'll love the Sunny.

Thanks Pappy, I do tow a 10,000# fiver a couple times a month. I know that is what is killing the stock trans. I too have a DP tuner with a 60 tow setting and there is plenty of power just not enough tranny.

I'm using a Suncoast tranny with DP tuner. See Sig. Works great!
