12v auto no exhaust brake although I plan to eventually since I have a HD torque converter, stainless clutch basket, and higher pressure VB and a deep well mag hytec pan w/ temp guage installed.
and will have a lockout switch.rd
Have you done anything with the thermostat? I think your best bet for staying warm downhill is the ebrake and cardboard or zip up grill type cover. You probably already know this but trucks with bigger turbo's and more fuel do warm up faster than stock trucks.
My 01 had a full billet auto trans with the lockup switch a few hundred hp additions for power and I had the stock hy for a bit then went to a hx35 and ended up with an hx40 for while before I sold it. With the 40 on the truck it was up to operating temp in less than half of the original time no matter what the outside temp was. With the hy and the hx35 I would be 10 miles into my basically flat trip to work at freeway speeds before up to operating temp. When I put the 40 on it would be up to temp by the time I got to the on ramp which is only about a little over a mile from my house. Plugging it in helped in both situations but wasn't as significant after the turbo change. BTW egt's ran around 500-600 degrees with the smaller turbo's under normal driving and 800-900 after I put on the 40.
