I installed a new Mad Dog transmissions tranny about 2 months ago and when I try and leave the line in starts in second gear when I spool up. Also when I self shift into first gear and gun it the transmission automatically shifts into second gear right away. Is there any adjustment I can make to fix this?

 

u can adj all shifting with the tune now that u r running a stout truck u need to get either hp r efi ls1edit and get that think move and u can adj all u'r shift points

 

Did your trans do this since it was installed or is this something new? I would put a scan tool on your computer and see if it is commanding 2nd gear. It almost sounds like you have a crossleak in the 1-2 accumulator.

 

It has been doing it since i installed it.
