    I have finally purchased all the aftermarket soft parts to upgrade the 47/48RE or A518/618 case. Now before the Dodge haters jump in, let it be known for me I have torn up The Ford 4R100 quicker than any Dodge transmission I have owned.

    The OEM's could build a transmission like this, but cost is the limiting factor, and consumers would complain. I have $3,500 in parts pictured below:dizzy:

    The Clutch & friction module is the Raybestos Gen2 Blue Plate specials Forward & direct drum. The overdrive are Tan overdrive clutch's. The Steels are Kolene Steels; which is a special Nitrated coating for high heat use & long life. The Large spring is a extreme duty Mega Overdrive spring the Mega spring is located in the overdrive housing or tail, and applies pressure on the forward drum or 1st & 2nd gear, the stock spring is 800lbs, the Mega is 950lbs:) the added pressure on the drums will mean no slipping.

    Billet aluminum 4 ring zero leak accumulator piston(one of the 47RE's main weakness's the OEM use plastic, and the piston has one seal & leaks; which is normal, but you have low line presure's or soft shifts) Also the OEM must consider drive ability, a built transmission does not appeal to some for daily driving

    Aluminum Intermediate Servo Cover & Aluminum Oversized Intermediate super servo

    Billet second gear apply lever 5 to 1 ratio & billet anchor & strut. the 2 gear band apply lever applies the pressure on the forward drum the higher ration means more clamping power & can hold that power longer.


    Generally when rebuilding a transmission you have three choices of intermediate bands Ridgid, Flex or extra wide Ridgid. You also have three compounds Kevlar, carbon fiber, or brass impregnated.

    I am using the middle or Ridged Extra Wide 2 3/16 carbon fiber band. This is bears the brunt of everyday towing from a dead stop. You can see how much wider the surface area is on the extra wide band. This wide band in conjunction with the 5 to 1 apply lever & billet anchor give you unmatched starting power to get the loads moving quickly all day long:)

    TFOD Shift kit or VB reprogramming kit corrects the lower line pressure of the stock 47RE/48RE, again this is a cost issue foe the OEM's to add this kit:rolleyes:

    The other parts are bushings, electronic upgrades, master rebuild kit, AMSOIL Synthetic tranny fluid, PML 47RE 8qt deep transmission pan is on order to keep her cool.

    Finally the heart of a bulletproof diesel transmission is a triple disk/clutch Torque converter with anti-ballooning plates to keep the converter from distorting under high diesel loads/torque

    I had a full billet trans built and it was the best mod I have done to my truck by far,night and day difference you will enjoy it greatly. just make sure you spend the time and make sure you get the bands adjusted out correctly.which pan did you get I wnet with the mag-hytec double deep.

    i went with PML for the Dana 80 rear cover, so I am going with the PML tranny cover. I agree 100% I have rebuild ever transmission I have owned to date no matter Ford, GM, or Dodge. Once you get the cheap OEM parts out it's all:), and you wonder how you survived without a heavy duty transmission

    Ok...Now I am confussed. You either have a carpeted shop or a wife that is a saint. If I ever brought parts in to the home like that, the home would be that last place I ever see again. Good luck with the upgrade. If my 5r100 ever gives out, maybe I'll give ya a call.

    I have been known to bath my transmission case's in the bathtube:rolleyes, wife has found transmission parts in the dishwasher too:): The pics were taken in my office at home the only room that has carpet in my house. I would not leave these parts at my shop as they might grow legs:dizzy:

    Here are the teardown pics from today, the OEM frictions were still usable; however the flimsy OEM intermediate band was showing some wear. My shifting issues were related to the Electronics & valvebody. So the majority of this rebuild is overkill if your on a budget.
