My truck is still stock and I hear about the AFC mods and the 4k GSK kits but my question is before I do all this, with an automatic transmission what do I have to do so that I don't break something expensive?

 

At the very minimum I would upgrade your valve body and upgrade to a good single or triple disc converter.

 

Valvebody, Good Torque Convertor will help it out alot

 

how much will a torque convertor and valvebody hold i have only put in 90hp injectors in so far i had two bad ones when i got the truck so i upgraded them at what hp will the stock trans give up i am new to dodges and there trans thank for your imput

 

well don't know on 12 valves too much but with whats in my sig the stock auto is screaming for mercy . i just swapped it in and wanted all the bugs worked out before i upgraded it anyways so i didn't care much. i would do like they said, put a converter and valvebody in and save up for a full build

 

ok i have been working on getting the money to get the vb and tc i need the truck to move back home so i would like nowing that the tran will make it the 1350 mile to get back to wisconsin hauling my tool boxs home safe and sound thanks for you imput and time replaying to my post

 

as long as you take it easy i think you will be fine

 

In my dealings, I find that most trucks act differently based on miles and what kind of life they've lived so far. In my truck, the stock auto starting slipping just after adding a #6 plate at about 120k.

 

This isn't an exact recipe, so don't quote me. But I've used this for everything, and my auto's have yet to grenade on me...

Anything over stock, the stock tc is almost guarenteed to slip. Get a good single disc if you aren't going over 500hp. Modding the vb, whether it is a shift kit or a full vb, will also help the tc hold on better.

If going over 500hp, getting a triple disc is a good idea, along with input shaft. If you go over 500hp and actually use the power a lot, I'd put in decent clutches and stuff too. If you are going to do 4x4 launches, then you'd need an output shaft too.

Doing a gsk won't hurt the trans at all, as it's not adding actual power, it just broadens the powerband.

 

ok thanks alot i will keep that in mind when i order parts my truck has 390,000 on it and the back of the fram is bent down and the brakets for the air bag helpers are all bent to crap i am sure thats not the orginal trans have no idea how many miles are on the trans i pulled the pan and fillter last week and it was ok not great who would you guys recomend to get the parts from? thanks for your time and help
