Oh i see. Thanks for the reply i was just curious to know since i have a lm7 in my storage wondering if my l83 kicks the bucket if it was swappable. The lm7 when it was in my gmt800 was flawless.. I did not do a afm delete just coded off. I already have the thermostat bypass for the trans. Would you recommend anything else? To prolong lifer issues its a 2014 with 220k miles
