2nd Generation Dodge 24 Valve Powertrain

have had my truck a few months. It worked well for about 1000 miles and has been a nightmare ever since. without getting into all the details of all the parts I've replaced and the ridiculous number of times and ways it's left me stranded in about 3500 miles, I'll just focus on the transmission issues here: it started gradually shifting worse and worse. Initially it seemed to mostly be 3rd gear, but eventually, over the course of a couple weeks, it was all the gears. Grinds the worst and the most consistently going into 3rd but now grinds in all the gears randomly, and the shifting in general is very hard. Can't get it into reverse without putting it into se…

From reading it seems normal idle for our trucks in park is 800-850. Mine idles smooth at 750, and I’m pretty sure it always has. Been paying closer attention to the truck as I try to figure out this low boost issue and some other little things. Truck starts right up, 1/2 a crank at 20F this morning. My concern is the Nations 180 amp alternator. Just making sure this isn’t effecting performance on that. Is 750 in the acceptable range? That’s 750, no ac. Auto trans in park. High idle kicks in as it should.

Hey all, sadly back again Noticed a little bit of oil was coming out around that gasket on the intake horn and the bolt there. Backstory, previous turbos I had a year ago ended up both going (P/O had a homemade budget compound setup). I swapped setups with a guy and the turbos no **** blew and were gushing oil when they went on his truck. I had a haze at idle and told him I didn't know condition etc and he still wanted them for the piping at the least. I'm assuming there was a good amount of oil in my intake system (intercooler etc). Is it possibly it's finally making it's way up? I have a brand new GT turbo with maybe 2k miles on it. …

Hey Fellas, 02 cummins 3500 dually 6 speed Intermittent dead pedal. Sometimes while driving it sputters bit or it doesn't accelerate, does not stall out, it's just kind of runs flat and pedal does not respond as it should. Intermittent. No rhyme or reason. Some days it's fine, other days seems like it only happens for the first 15 minutes after starting when the truck is cold. It kind of feels like when my APPS failed a few years ago. Could my issue be as simple as resetting the APPS? Have not tried that yet. More info: Current mileage: 250,000 Installed new timbo APPS 2018 @ 226,000 miles I checke…

Hey everyone, I have been playing with my 47re with my pacbrake. I'm starting to wonder what is a good healthy line pressure when engine braking. Right now I'm seeing 80-85psi at idle in drive, and driving down the road were about 110 with my foot out of the throttle. In the throttle I'm seeing about 125psi. When I'm engine braking I see about 115psi going from 2,000 to 1,250rpm. When I'm downshifting and in 3rd, I can move it to M2 and it will downshift at 32.5mph 1,250rpm. I have a lower stall torque converter and it seems to brake hard even on second. I was looking to see having the TC lock up when downsh…

My current Heat exchanger is a little crispy after the 20 years of service and a few years around some road salt. I've seen several listings on Heat exchangers varying in prices from ~$800 dollars to as low as ~$200 dollars and curious if anyone has found a difference between them or has had issues with the different options out there. Trying to save penny's where I can without risking the reliability of the truck. Eventually I also do plan on adding an additional cooler in the loop but curious if size of the cooler will add (if such a thing) too much restriction. And lastly, currently I have my Trans Temp sensor located on the output of the trans, but I…

Hello, I have a late 1999 24 valve sport model appears to be 4 wheel abs, just extra information. Have edge comp, S&B cold air intake, 5 inch turbo back straight pipe, and RV injectors. Rest of truck is stock. Anyway, I am just curious as to if it is normal for the stock temp gauge on the dash to be at 140*F on a cold engine in the summer. Sits for about a week then drive it off and on this summer 2022, temps reaching high 90*F. But yeah, when I go to use the truck after starting the temp gauge is already reading 140*F. I know that is not normal but I just would like a 2nd opinion. I also do have the Mopar1973Man High Idle/Eco Switch installed. It is …

Ive been off the site for a while due to so many circumstances over the last 3 years as im sure so many of us have. Im hoping some of the older knowledge is still floating around because i may need some help or if nothing else i can document the story a little bit here Back in 2017 i had the transmission rebuilt for the first time by a good friend at a reputable shop with plenty of experience. He did a great job. What was done then- (cause of failure was TC welding itself together and subsequently toasting the rest of the unit while i trying to get it home) billet triple disc, shift kit, GM sensor and governor, replaced one drum (with a good used o…

Just did the CAT filter replacement on my fass titanium pump.... called fass tech to double check which filter goes where since I couldn't find the factory instalation directions (had crappy service so couldn't look up online). They told me that the fuel filter goes on the side with two lines and the h20 separator goes on the single line side. Well guess what, that's backwards. I got home and found my paper printed directions. I only drove like 10 miles with the filters backwards.... did I cause any damage? Furthermore, why in the literal hell would anyone at fass tell me incorrect information?

I've spent the last two days working on the install of a new hx 35/40 turbo and pac brake unit. Today I finished up and went to start it with no luck. It initially ran a couple of seconds on numerous attempts to start it and then just completely quit trying to fire. Details: A few weeks ago I installed a kill switch in the grounding wire of the fuel pump relay. If I forget to switch the hidden switch to "on" it spins over but won't start and throws code 1689. Today, the spinning but no starting reminded me of the result of the kill switch being in the off position so I wired the relay back to stock configuration to rule out an issue with the switch with…

Yeah I've got a previous customer back. The white Dodge that I did the AirDog had a problem with 4WD and it wasn't locking in. First thought was CAD axle issues but after testing the transfer case and seeing if the shaft locks nope. Something wrong it the transfer case. I pulled the drain plug nothing came out but 4 drops of black thick oil. Removed the transfer case and open the inspection plate and ther is broken metal, plastic, and pieces. I'm heading to Boise Transmission warehouse to get a reman transfer case Tuesday morning.

Alright so after getting all my boost leaks fixed, I was finally able to install the ARP studs, and remove the Smarty tune. I’ll be installing the Adrenaline this week, as well as a set of Infinite Performance 7x.010’s. The goal was to have a reliable tow rig at around 325-350 HP, but a forum member lives down the road from me and is offering a really good deal on a 62/68/12 SXE. So I’m considering doing that and making my hp goal 400hp. Will this tuner/injector/turbo combo give a good reliable towing experience? Is that turbo gonna be slightly too big? Should I wait and get a 57/65/12? Don’t want a lot of smoke, don’t want 600hp…just a solid reliable 350-400hp for dd and…

I recently tossed the automatic and installed a G56 manual in my 98.5 short box. Love the trans but now I have too much axle wrap. My rear springs are on the soft side because I took a leaf out of each side to improve ride and offset it with a pair of coil springs. I have had traction bars before, on this truck and two previous trucks. Each set sucked. The last set I paid something around $700 because they were supposed to be good and beefy, but the heim joints quickly wore and rattled and clunked like mad. . .heims at both ends (bad idea and not quality ones at that). Also it seemed to bind suspension travel, ride quality wasn't that good. On…

I know most of you have looked at your oil pan and wondered if the oil pan can be removed easily. The answer is yes. You can remove the oil pan completely but you will need a few heavy-duty tools like a bottle jack or an engine hoist. The first thing you going to need to do is jack up the truck so the axle hangs freely. Then you want to drain all the oil from the pan. In my case, I had to do tie rod ends and a new drag link so this was all removed. I removed the wheels from the axle and allowed the axle to just hang freely. Loosen up both engine mounts bolts till the nuts are to the end of the threads. Now set up an engine hoist and hook it to the front hoist ring of the …

I have less than 10,000 miles on some DAP 50hp injectors but as many of you have said, always go bigger! I purchased some DAP 8 x 0085/100hp nozzles and put them on my stock/factory bodies that had less than 60k on them. A local FI shop checked out the bodies, installed the nozzles and popped them at 310. The increase in power going from the 50's to the 100's seemed greater than going from the stockers to the 50's. It has a nice little puff of smoke when you get on it from a standstill but is otherwise smoke free. I really want the power to kick in when needed up at cruise speed and I'm trying to pass some farm truck on the rural highway that is doing 53mph ( I call it th…

Hello all, just joined the page so please forgive me if I don't do this right. I have a 98 2500 24v auto, and ever since I've owned the truck I've been having this issue but just never attempted to do anything about it until now. I've just rebuilt my transmission to hold 550hp, am looking to add a tuner but I know I should fix this before I try to add more power. I have read the forum here about adjusting the apps and numerous other forums and cannot find anything to specifically relate to my issue. To start, my issue is that when I plug in my OBD scanner, my APPS sensor was reading 8.6% at idle and 71.3% at wide open throttle. So, after doing so…

Just wanted to express appreciation for communities like this. I haven’t posted/interacted much but I’ve been reading and applying what I’ve read. I’m too green to really chime in other than questions, anyway. I picked up a truck a couple months ago with the intention of building it into a tow rig. It’s not a full time commercial rig but I work remote and the wife and I want to be on the road a lot, so getting the truck ready was a priority. Doing WT’s ground wire mod fixed the annoying TC cycling issue and the vp44/injectors sound happier with a lift pump. Reading here has me settled on a Quadzilla and likely 100hp injectors (rather than 50’s and want…

I am planning the do a cooling system maintenance on my 1998.5 and have not been able to find the correct thermostat for it . The ones that I have been handed are the large one for the 12 valve. I did try one about 7 years ago and had such wild swings in temp that I thought I had done something wrong. After much thought and trouble shooting I found that the thermostat did not look like what I removed ( my fault I did not compare them when I removed the old one). I went back with the old one and finally found one that matched. Here I am 7 years later and the only one that I can find is for the 12 valve and in their data base it said that that is the only one fits from 89 t…

I replaced my ECM and FCM plugs with pigtailed aftermarket plugs. When I started the truck it idled normally but when i pressed the accelerator there was a loud grinding noise under the hood. What could I have done to cause this? It sat for over a month before I made the repair. Disconnected batteries first. Spliced wires one at a time. Reset throttle sensor before starting. No codes.

It surges when eng is cold and after it warms up it seems fine. It reminds me of a tank half full of water, you feel the push then it drags back. I just installed new vp44, new injectors, crossover tube o rings, new airdog 165. Talked with Lenny at DAP and he suggested hooking up Iquad and see what datta it might show. I havent installed the Quadzilla Iquad yet because of this. I also just reset my apps a few minutes ago to see what happens in the morning. A real head scratcher, I hear about ecm's doing this but its always when it heats up, or the vp doing this as it heats up. This gets better as it heats up.
