Shift kit for 48RE
Has anybody put a shift kit in their 03-04 and how do you like it? Does anybody even make one, or do you have to buy a whole exchange valve body? Who has the best prices?

Most shift kits are fairly easy to do, I had not checked availability on these trucks because all I've ever heard is "valve body". Maybe they're just brainwashing us into thinking we can't do anything but bolt in this or that, and we can't think for ourselves and install a simple shift kit

What one buys with a VB from a trans shop is their experience.
I know for a fact the common kits have you drill in the casting of the VB and I don't like that. It can add to the drain back issue that is common for the Dodge auto.
Unless you KNOW trannies, it is best to buy a VB from a good shop.
I am quite surprised that Trans-go hasn't made some changes.

shift kits
hey guys just be careful with the shift kits and how much they up the line pressure. if you get the pressure to high the govener pressure sensor will set a code and the trans into a limp in mode and you will be taking off in third gear. just installed the dtt stuff in a fellow members truck and this stuff is awsome. it also comes with an module that you fool the pcm with so it doesnt see those higher pressure numbers and set a code. you can also use a resistor inline but you spend more time finding the right one. the dtt module is adjustable . also as j- fox stated you are also paying for there knowledge when you buy a valve body and they do this stuff day in and day out so id say they know there s***. just my 2 cents worth.

Guys, in my opinion you are all spending WAY too much on tranny parts. They are not that expensive. AXIOM sells a modified billet cover TC made for modified Cummins (not triple disk)for $369 plus an $80 core, the valve body mod parts are about $100 or so for everything. If you are spending thousands on a modified valve body and T/C you are throwing away a lot of dough that can go to other things like your wallet. I have had these mods done to my truck and everything including labor was less than $1000.
Below is a list of what needs to be done and where to buy. If you dont have the knowledge to do this work yourself any performance transmission or off-road performance shop should be able to do it for you. I would stay away from regular tranny shops like Nationwide, etc since they do not do performance work very often. I had my mechanic do the work and he did everything for $250 labor, we have a very good working relationship but even if a shop charges you $500 you are still saving a substantial amount of money. Good luck.
Important : These mods will NOT work on 05 models. In 05 the tranny was changed and is controlled more by the computer which will not allow changes in line pressure etc to work properly.
Valve Body/Torque Convertor upgrades for 48RE transmission:
Parts required – Superior VB Kit (99-up A500/618), Superior part # K500-618-L
Sonnax Pressure Regulator Valve, Sonnax #22771-A-02K
Sonnax Manual Valve, Sonnax #22771-09
Sonnax 4-Spool Convertor Valve, Sonnax #22771A-01
ATC/Repco Torque Convertor, ATC/Repko #CR70X-S1
Installation:
1 – Install VB kit as per instructions, with the following exceptions:
a – Do not drill the Pressure Regulator valve wall as directed – install
Sonnax Pressure Regulator.
b – Do not drill the valve body casting for the manual valve supplied with
the kit – install Sonnax Manual Valve.
c – Replace 4-Spool Lockup Valve with Sonnax 4-Spool Convertor valve.
d – Line pressure setting using the blue spring is set with the aluminum
gauge provided that is also used to measure cut for the throttle valve.
Set the stop halfway to max for use with the heavy duty S1 convertor.
Not necessary to ramp line pressure to the max setting.
2 – Remove the cooler line check valve; Sonnax PR valve moves check valve into
VB. Original check valve is in one of the cooler lines at metal/rubber connection at the fender well, and is part of the coupler.
3 – Replace stock Torque Convertor with ATC/Repco convertor.
The Superior VB kit and Sonnax valve set works extremely well on all model RWD/OD Dodges.
1 – Keeps the TC charged at full throttle and fluid flow at max.
2 – Allows for extended idle in Park by allowing for full fluid circulation, unlike
the stock setup.
3 – These modifications are highly recommended with any rebuild and are perfect
for the lower stall S1 convertor, and work extremely well for lockup.
Call Bobby at AXIOM in Charlotte NC (800) 633-3340 to order parts.
I dont think these mods can be done on 05 models. Only 03-04 with 48re.
Be sure they sell you the CR70X-S1 model TC, the CR70X model is just a stock replacement from what I understand.

I just completed the valve body mods listed above yesterday and so far I am very happy. I probably could have set the line pressure a little higher and I may adjust the throttle valve cable some but that stuff is just personal preference. I didn't do the converter, but I will in the next few months. This stuff may not be equal to the big name places but it is probably more than enough for me.
It shifts much better, thats for sure. I will drive it more in the next week and report back with more opinions.
parts were cheap and it took me and a friend about 5 hours to do it all. Thats being very cautious.
