Tranny limp mode!
 

Switched from Smarty to H and S mini maxx and towed my 5th wheel for the first time since the change.

I towed for the first time since installing the H&S mini maxx and ran into a problem. When the tranny got to 205 degrees it would go into limp mode. Is this a parameter that is adjusted in the tranny program? Can it be raised to 245 or some other number? What is safe? Codes that I would get when tranny temp went to 205 were P0871 and P0218. I also got P0700 one time. If I reset the codes to the truck would go out of limp mode and temps would decrease back to 205 and then the codes would reappear along with the limp mode.

Any ideas anyone can give me would be great. I have a couple of trips planned that will require the truck to be able to tow a trailer.

Thanks
