    Help fixing transmission gears switching

    Hello guys I'm new to this diesel world, hopefully someone will be able to help. so I'm having issues what I think my transmission is taking long to switch I just got my truck back from the mechanic that deleted my truck and installed my mm3 from drd. I have 33x12.5r20 when I go to tire diameter it says 33.20 I want to know if that's correct or what # do I put in? Any help will be highly appreciated thanks

    for the relearn process its where your tcm relearns what pressures you're demanding and when you dont do a relearn the trans doesn't run right and could lead to issues like burnt clutches. https://revmaxconverters.com/wp-cont...ons_revE-1.pdf the link is for revmax tranny's but i use this guide to do my relearns
    you need to re flash with your tune file and do the relearn process
