My question is... how much power can my auto trans handle. Its a recent rebuild and id like to wake the truck up a bit with a new fuel plate. I just want a little more go to tow my camper, not enough to start buying parts. What # plate and why? I was thinking #8 or 10. Am I on the right track?

 

Well, firstly lets see what year you have and maybe a bit more detail on what internals you had done to the tranny. That will dictate most of what you want to do..

I would suggest a Governor Spring Kit firstly before getting into a plate.

 

Truck is a 95 2500 2wd. The previous owner told me he had the tranny rebuilt about 50000 miles ago with heavy duty parts. $2800. Thats all I know. It runs and shifts perfect and he hasnt towed a trailer since it was done. The truck is all stock with 260000 mls- but runs great. Thanx, Jeff.

 

That is a tough question without knowing exactly what was done to your trans. If I remember right the last stock 47rh I bought cost about that much.

With a stock trans while towing I could slip the t/c with a #11 plate and no other engine mods. You may need to back out of the throttle to keep from hurting the trans if it isn't heavy enough to handle the new plate.

 

Ive heard something about sliding the stock plate forward- any gain here?

 

There is definitely a gain to be had with sliding the stock plate. Tuning the plate and AFC settings is key on these p-pumps. However, as was suggested, I would look into getting governor springs first. The truck will 'feel' more powerful without adding more fuel and the tranny will be more in it's comfort range, RPM wise.

Ok governor springs/ afc where are these located? I keep hearing about them but have no idea where to find them.

 

You can get an upgraded tranny for $2800 so I wouldnt rule that out. Get a gsk first and grind your plate to a 100 profile. You can adjust how much fuel you have by sliding the plate front to back and adjusting (adjusting is nothing technical, you just add or remove fuel at the low end until it runs good without too much smoke) the afc housing. You will know when it slips and when it does, just back off the plate a little.

 

Do you know what the injection pump looks like?

 

You need to read this> http://www.dieseldatabase.com/read.php?id=58

 

Everything I explain will be from the drivers side view.

The afc housing is on top of the pump to the right of the injector lines and is about the size of a playing card with a pretty big allen screw cap on top and a boost line running to the back side.

Inside the allen screw cap is the starwheel. if you loosen this you will have more fuel as soon as you stab the throttle (sometimes causing thick black smoke from a take off)

Under the afc housing (you have to remove the 4 bolts, one of which is a break off screw and will require a dremmel and screwdriver to remove) is your fuel plate. Pretty simple, 2 screws holding it down. Slide it to the front of the engine for more all around fuel slide it towards the cab for less fuel. Pull it out and grind it to a 100 profile if you want to do it once and do it right. I like the 100 profile because it fuels well and is easy to grind with a bench grinder.

Now the govenor springs. They are inside the pump and the easiest way to access them is down and to the left of the afc housing. There should be a large plug (1.25-1.5in dia) and will take a 3/4 or 7/8 socket to remove it. To access this plug you have to remove the shut off solenoid. The bracket to the shutoff solenoid is connected to the bottom 2 screws of the afc housing and one really long one in the back. If you dont immediately see the govenor springs once you remove the access plug, you will have to turn the engine over using the nut on the alternator until they appear.

 

Thanx guys, Ill check it out.

 

Being a noob as well i can say to do the 3gsk, which i just installed. It may sound like a hard install but is perty simple. Out of all the things ive done to my truck (see sig) i would have to say the 3gsk made the most noticable change for the least money + it makes driving with my junky auto more enjoyable. I have only ground my stock plate to a 10ish style and pushed it all the way froward along with the afc. I can slip my stock 47re quite easly so if your trany is not built better then stock be easy on it.

good luck, matt

 

As I understand it, do the gsk and leave the stock fuel plate where it is. I dont want the trans to go out the truck isnt worth a 2-3000 dollar transmission job. I may just leave it alone...

 

The GSK will make it feel like more power without adding a thing..
