HPtuners transbrake questions

[Andy13186]

I have a tune with the transbrake feature but I have a few questions about it. I tried it out earlier today for the first time but on the street just experimenting... It does seem relatively useless for the street I suppose because traction isnt good enough to hook off a tbrake launch -atleast with stock tires.

Heres what I know :

To activate : hold left paddle, hold right paddle, hold left foot on brake, right foot jab the throttle, let off brake with the left foot. At this point I am not sure what % throttle to give it... 100%? 50%? I think it will hold at around 3k rpm. Also while its in this state you can click the left paddle to bump forward a bit. Release right paddle to launch.

Takes a bit of practice to master it since its a lot of stuff to do. I was not sure what percent throttle to give it while the tbrake was holding so I didnt try it much since I didnt want to mess anything up. I also notice the trans heats up fast if you use this, what would you guys say the max safe trans temp is? I was trying to stay under 200 but even without using the Tbrake ive got 205 or so while driving hard.


Anyone have any tips or advice? Thanks.

Prepare $$ for new half shafts. Pretty much worthless without a good DR or bias ply.

Look at your trans temp gauge. 205 is not overheat range...?

I dont have the digital dash, I am monitoring on the torque app so IDK what overheat range is. I dont think 205 is overheating though because if that is... it was way too easy to get there just driving relatively hard on the street. Id guess 220 is overheat range? idk .

I dont think halfshafts would break on the street. I do think a slick may help stuff survive on the track. For now I am just trying to learn how to use it best aka what throttle position to have while on the Tbrake.

Halfshafts will definitely break on the street.
Throttle % just determines at what rpms you want to launch at.. At 100% throttle you wont get past 35-3600 rpms.
This is completely useless for you unless you're on a set of drag radials. Street tires are too hard for this and the big shock from a transbrake will cause you to spin everytime on street tires

Ford sez the normal operating temperature for the 10R is, 96°C (206°F) to 101°C (215°F)

The trans temp gauge shows 260 as starting the danger zone.

I would follow the old MERCON temps, those are 225 max uninterrupted running temp, the closer you get to 250 it calls for a 30 minute max operating limit and stop and let it cool down.

As far as throttle position on the trans brake, the purpose of the trans brake is so you can floor it, but don't sit on it more than a couple seconds as they are extremely hard on the internals.

If you arrow over right on your gauge display (trans temp) it shows you an actual gauge. I have base GT w/ no digital dash. 200-205 is in the middle of normal temp range. Perfectly normal. Hot is not until 260 plus.

You need cradle locks, vertical links and new upgraded halfshafts to even think about running a transbrake. Add about 3 grand in rear end goodies including DR/slick. Lol. What are you doing...?

I disagree with the cradle locks and vertical links. Halfshafts and radials for sure.
My car is completely stock suspension.. 1.35 60's. I can name another dozen that have stock suspension that would agree as well

You will has less drive train stress with street tires because you will just blow the tires off . Once you get it to hook up say bye to your half shafts after a few good launches . trans temp will shoot to the moon when loading up the converter then cools down once locked up .
