H&S Mini Maxx Questions

I downloaded the Hot Damn tune and the 45 MPG TC lock up. When I went out to do my tranny learn, the tranny shuddered for a split second (until I let off the throttle) when shifting from 2nd to 3rd. Do you think I did any permanent damage?

Also, I always thought that torque convertor lock up, or an automatic tranny shifting in and out of lock up while towing was very bad for a tranny, causing it to overheat if you are not careful. I am wondering if having my TC lockup at 45 mph is going to stress my tranny? Also, does the TC lockup turn off when I am in tow mode?

I would like my tranny to live long and prosper.

I am going to give you a bump.

I am also interested in your well thought out, and brilliantly articulated questions. You are indeed a valuable member of this forum, and even a treasure to some. I am honored with your mere presence, Mr. Canteenboy.

I have to reply to this thread after a post like that! thanks for the good laugh

It is normal to feel some "shuddering" from the transmission under hard load conditions. I highly doubt you have done any damage.

Locking up the torque converter can cause more stress onto the clutches inside the trans, but it also allows more direct contact between the engine and the pavement. When towing, most guys like the Torque converter to lock-up later, when the motor can handle jumping to the next gear without "lugging" it too severely.

In the end it is up to your driving style to decide what works best for you. Personally i use Race shifting with 55mph lock-up, and put some ladder bars on my truck. Shifts like a dream, never misses a beat.

Does the tow/haul mode keep the lockup from occurring?

No sir. Just makes it come in a little later in the RPM range usually.
