What should I change at the trans tuning after loading a hotter tune into a stock trans truck? I didn't know if I should change taps, put it into fast learn, change shift points or leave it alone and let it learn? What is the proper procedure and how long does it take for the trans to relearn? The trans is acting funny and shifting inconsistently, especially in t/h were it is lagging between shifts. In regular mode it acts as in t/h when in 5th. Sorry for all the questions but I am new to tuning and did not want to hurt the trans. Sorry if this is in the wrong section, but I tried the other one with little results, maybe I didn't word it right. Thanks in advance for the help.
