My transmission is body jarring me going from 5th to 4th on every down. I mean it’ll throw you in the dash it’s so hard. I was running Tyrant 230hp engine and trans tune for about a month. Until today, today I put it on the 50hp tow tune since it hasn’t been updated since last year I thought maybe it was jarring since the updated it last month on the 230hp tune. It’s still body jarring on down shift. What’s the cause? Is it in the tuning or the truck. I like a firm shift but not neck breaking.

I have Tyrant tunes and mostly run on 65hp tow tunes. From 6th to 5th downshift every now and then I will get a violent one.

I never had an issue on all my Tyrant tunes. How's the tranny fluid look/smell? Can't hurt to ask if there is a revision or if he can revise yours.

I called them today and their going to send everything over to Kale. It’s on the 50hp tune as of yesterday. I was running the 230hp tune. I also have oil in my exhaust and blowing white smoke at idle. I just had the CCV box to the updated 18+ box. So I don’t think that’s it

Fluid is still good I’m debating on having it flushed and Changed though since I’m almost at 70k miles
