I just bought a 94 ram diesel 300,000 miles. The truck runs great, but has some querks. The transmission when cold does not move the truck. If i let it warm up for 20 min it drives and shifts good, but does slip a little when shifting under full excel. I am going to change fluid filter and adj bands this weekend. Is there anything else that can help. I would rather not replace the transmission until my 92 f250 460fi (8.5 mpg) sells.

When I start working out of the truck I will be putting about 100 to 150 miles a day 6 days a week. What mods can i do to get the most MPGs out of it. 7000lbs is the most I will pull and that is maybe 20 miles a week.

Is there any way to tell if the KDP has been done. The way this runs I would think the motor has been gone through at some point. I had a 95 suburban Diesel that I loved, but the dodge will run circles around it.

It needs paint and trans work but for 800.00 I could not pass it up.

Thanks: Jeff

 

Welcome to DTR

Sounds like a good buy.

Let the truck warm up in neutral. Then the tranny will be pumping up pressure while you wait.

I would have the tranny rebuilt when you can and then you know what you got. Sounds like it's worn out.

 

Welcome to DTR!!

For 800 bucks ida bought the truck myself too, the engine alone is worth more than that, you did good. U want more MPG out of your truck, i suggest getting the injector pump timed, it will help your mpg drastically, i know with me it did, almost 2.5 mpg, and for you, here is some more reading as towards gettin more power out of your ram as well, and on some of the parts that you will be readin alot about in the 12V forum...

THIS is just to get a little more power out of your ram. You can do serveral things, i see you are getting gauges, and you have an air intake on the way. which is good. Now this is an into to the main power source of the ram, Your P7100 Pump, and what you can tweak on it for more power. You can also time it, but thats advanced, well at least for me... use this as an intro more than anything.. I tried my best to explain it.... here goes... and

I meant to say post.... sorry.....

Here is an intro the link to the pic might not work, but u can see it as banks plate in my gallery.....

to get more power out of your truck the first and foremost investment is a good set of gauges. These are a must anytime that you are adding more fuel to your mix.

A governers spring kit, Reffered to as a GSK is a wonderful investment that widens your normally narrow powerband from the 12 valve engine and allows you to fuel hard to at least 3200 RPMS or so, before it starts to defuel, this is all dependant on your governer arm adjustment and your plate positioning. A Torque, or fuel plate should come next. NO one really follows the plate guide anymore and the most popular plates nowadays are 100 (PM northslope for wicked work! ) and a zero plate. Piers Diesel Research and Hot Rod Diesels have them for the same price, The fuel plate... here is my explanation....

Torque plates.... ok this is a torque plate right here... https://www.dieseltruckresource.com/...=500&page=1

More commonly reffered to as fuel plates, they come in different numbers to explain how "aggressive" (for lack of a better term at the moment) that they are 10, 8, 6, 5, 0, and 100, zero being a flatt plate that bombards the pump with fuel, and a 100 being a ten plate curve with no top end defueling, much like the zero.. The one you see there is my banks plate, screwy yes, i know, i dont get it myself. that plate goes in the P7100 injector pump, It goes under what is called the AFC housing, which has a little starwheel on it, the starwheel can be accessed with the removal of the hex dealy using the the right hex head size plug, and u loosen it for more smoke, and better lower end, and tighten it for the inverse. Use a good screwdriver.... furthermore... You will see four screws there where the starwheel is, two that are flatt, one that is possibly a breakoff screw that can be a real PITA to remove, take a hammer and good screwdriver and bang the tar outta it, it will come off, if that fails, left hand drill bit... Looking down the driver side, the top left hand is the breakaway, and the top right is a regular screw as well, the bottom two are 8mm bolts and you need to get around to one that is in the back of the AFC housing that holds that fuel shutdown solenoid in place...

Install time, for a newbie, well it will take you about a couple of hours at most. If you read my literal "dissertation" of a post hehehehehehe. it tells u the procedure on how to do it. Your only real problem might be that break off screw, especially if your truck is stock, However, nothing a good strong screwdriver and some persuasion cannot take care of.

The other tricky bolt is the one (if you look down from the drivers side) behind the Fuel shutdown soleniod (electronic hooked up deal that bolts in front of the injector pump, easily removed with in my case an 8mm (and most should be too) socket and pull out the two bolts. when you undo those ull notice that there is one in the back that is holding the housing, you can just loosen the one in the rear using a deep 8 mm socket and just move teh shutdown soleniod out of the way, (downward) and then you can get to the plate..

When you are in there its simple adjustment, u just remove the stock plate and put the other plate in place of that one. NOTICE you have some play here. If you dont have gauges, dont set it full forward, If you do have gauges set it forward for a 30 or so rwhp increase!

Now put it back together and you are done. Installation is simply the reverse of removing it.PS having a magnetic tip screwdriver REALLY HELPS...

Which one is right for you.. id say the ten if you are not gonna be that aggressive with it, but the 100 is downright WICKED!! that be the one to go with, the zero is just too much at the low end for me but for dynos and racin, its awesome!.. The zero, PM Northslope AWESOME AWESOME WORK, and ull be helpin out a fellow DTR member, and the zero plate you can grind yourself, well you can do either or, but PM northslope do a search for plate grinding, started by gunracer1.. good instructions..

Either ways, you are going to need a clutch or tranny work if its an auto.....if you are going to play hard, in most cases if you just want a modest power gain, just get a 10 plate, set it a lil bit forward, and a GSK will wake up your truck. In the stock position its easily drivable and fun as well.

Waste gate, if i was good with pictures id put one up for you, but im sure you know what the wastegate looks like, that head looking deal, it is usually hooked to a rubber or similar airline, you want a little more boost? You can get a longer hose or pinch it up, There is a thread, i dont member where tho, where it shows someone improperly blocking the wastgate with a screw.... Well that aint good.. Anyways

Also make sure you get the KDP done on that truck as well... Not hard to do, look in my previous posts, KDP Report Using TST kit, or somethin similar to that......

PS this is cut and paste of other posts, sorry if its redundant....

Best of luck and hope that this helps you...

Congrats on the buy, and welcome to the DTR. I agree with bumping pump timing. It gained me a solid 2MPG.
