Tuning Question

I have been looking around on here for the past few days and I'm learning a lot about these Jeeps. Ive only had mine now for a week. It has 60,000 miles and its bone stock. I was looking at buying the Trinity tuner for it, the question i have is i was looking at prepping my transmission. I see you can buy a TCM for them but will the trinity tuner have the capability of changing the firmness of the trans?

Also what do you guys think about buying a valve body for it and getting the transmission services at the same time of course?

Thanks for the help guys.

Brian

Brian,
Search harder...none of the tuners can change shift firmness. You don't need to prep the transmission for a tune. If you are going to do a valvebody, when servicing the trans would be the best time since the pan has to come off anyway.

Our Jeeps do not have the ability to adjust the firmness of the shifts in the hand held. If you get a custom tune the tuner can get you a firmer shift to a certain extent. I feel a valvebody is a good investment if your gonna do a tranny service that obviously is the perfect time to do it. A trinity is good also, that's what I run I preferred that to the predator as I didnt have to run a laptop also to datalog. Nice thing with the trinity is you can run a wideband with it and watch the a/f ratio. And what he said lol

Well I was going to get the trans all ready before putting more power to it. I have always worked from the rear of the vehicle to the front instead of adding power then breaking stuff to the rear haha. My plans is to get the Valve body and fluid change then in a few months im putting a cam and heads on it. Of course a tune as well. I just need to find a place out here than i can take it to get it tuned.

You guys have any input on a place to get a Valve body?

Thanks for you help.

So you think that the valve body wouldnt be worth it? It shifts very crisp right now and down shifts perfect. I think that 72 year old man that had this before me didn't get on it much haha.

in my opinion , not at this stage,
once you do a Johan toon your gonna notice firmer shifts,
hell even the can tunes in trinities firm em up , you cant adjust it but when i look in the cmr software i see how they did it ,, very nifty
