Help 5r110w
I have a 2009 f250 that I am on my second rebuilt trans in 3 months and still am having tha same issues. The truck was tuned with x4 tuner with caned tunes no cats but still has the egr. Also has 6 inch lift with 37 14.50 r26. The trans shifts very soft at light throttle and hits every gear but at half to full it is very Erratic especially 4 5 change like it can't decide which one until I let off. Would some custom tunes help or did I get stuck with another bad trans. With the first I got 1 code for tcm communications error. This one has not given me any codes yet. Thanks for any help this is my first diesel switched form mustangs and camaros so I'm lost
