2nd gear start sled pull

[zuhlke07]

Looking for info on modifying my tcm tune to make a 2nd gear start, in 4 low with tow haul on


I've found some info searching Google and such but nothing for sure on it being in tow haul only.

I've someone has the tables that need changed for this that would be great!

Look at your shift speed and rpm tables, you can set the speed to 0 mph in 4 low. Play with it a little bit its pretty simple to figure out.
