2nd Generation Dodge 24 Valve Powertrain

Good Morning all, well it seems like every 6 months or so this issue returns, i just slayed that dragon last night and its really getting old. my battery clamps are not going to take much more of this before needing to replace them so here is the low down on the recent findings, the Ground on the primary battery has the acid build up, the other three did not. the problem was only presenting itself at speed between 40 and 50 (in the past, this would happen at any speed above 40mph in OD) i have a switch that i can use to kill my alternator (story for another time) so i killed it thinking it could be related to the alternator and the heat we been having. nope is…

I put in a tc lockup switch last night and followed directions from TST. However, after it was all done I tried it out and of course didn't work. My truck is a 99 model. I checked the switch and all the wiring and it seems to be okay. Anyone know what I did wrong or what I can do to fix it?

So I installed a tc lockup switch last night, and I'm not sure where I went wrong. I followed the tst website link but it doesn't seem to work. My truck junction box looks a little different than the one in his schematic but I'm pretty sure I did it right. Here is what the truck is doing. First, with overdrive off, I'll get the truck to second gear, and flip the switch on, and nothing different happens. It'll shift up to next gear as I increase speed. Then I can come to a full stop and the truck doesn't want to stall or anything. Or I can be cruising at 35, and punch it and he truck will downshift. The only thing that seems to be different is if switch is off, …

So, after 278,800 miles, my virgin 100% stock automatic has had its first hiccup. A couple days ago when I came to a stop it kept wanting to lurch forward, dragging the engine down. It doesn't kill it but it is lugging. I did some Googling but am not finding anything with the exact symptoms I'm having. I think it's the TC solenoid so I ordered one and will try replacing it. During normal driving the trans essentially operates normally, when the TC locks at its usual time the engine RPM drops, and it unlocks and relocks as I let off and back on the throttle. Basically, everything works normally but it acts like the torque converter suddenly went from 80-wha…

For a while now, I have been debating if I should put a TC switch in. I know of the benefits I could get from it, but what about the negative?I want to do the switch because I want to maximize the fuel milage by reducing the fluid coupling of the automatic, and reducing heat.Anyone done it and what to do and not to do with it? At that rpm do you shut it off at? Also, could this be a good way to substitute for being able to use an exhaust brake?

As title states, my tcase went crunch on the way to North Dakota for my new job. I'm assuming the way it locked up the innards are toast. I had to disconnect both drive shafts to move it. As of now, the truck is going to be put into hibernation until I figure out what's going to happen next. That depends on whether or not I can get a decent case for cheap enough. I've also considered adapting it to run an np205, and hopefully not have to worry again. But I really don't want to have to get new yokes and drivelines. What do you all suggest? Who could rebuild it for a reasonable amount? Who sells gears and stuff besides all state? The truck has 4.11s…

Having a drivability problem (98.5/24V/4sd auto/4x4/4.10 gear) I’m losing about 200 rpms at speed. Feels like its losing torque converter lock up at about 70 mph. Lock up is obvious and strong at 45 mph but at 70 the rpms will fluctuate between 2100 and 2400 with no change in speed. Changed out the tcc solenoid/over drive solenoid, governor solenoid and governor pressure sensor no change. Installed manual tcc switch, sitting still, truck in drive flipped the switch and killed the engine but no change in lock up at speed. Some lose in fuel economy, about 1mpg. Took it to a transmission shop they said they couldn’t find anything wrong, computer commands lock up at the right…

Back in July I lost ECM output for my lift pump. I tested for AC noise at that time and had no issue so I corrected and added a fused power source and now it runs off a switch. BTW alternator is believed to have the same milage as the chassis which is 332,732 Two weeks ago to transmission started having issues with torque converter clutch lock up it was hunting a lot. I threw a scanner on it and started collecting live data. I find out my accelerator pedal position sensor will not register over 80% at wide open throttle. At this point I was very confused so I started testing more things including A/C noise again and the alternator is still fine my batteries…

Rookie post even though we've own this thing since 2005. Often herd there are no dumb questions, well here is one Our Trailer and stuff in bed of pick up is about 12,000 pds loaded. 2001 truck is stock with 47re with a 4:10 rear end. When going up long mountain grades, I make it point to not go over 1150-1200 on my pyro. On long upgrades I usually end up falling in line with the big trucks and just chug up to the top about the same speed. But not unusual to be passed by other people pulling about the same weight, sometimes like I'm standing still. I understand newer equipment has bigger horsepower. I don't care if I'm not the first one to the top of hill or not.…

Well I've made it home for the summer and it's time to start tearing this thing apart. I will begin tomorrow, but yesterday I took it to the dyno. Laid down 503 / 1215. I was very pleased with the numbers, but the knocking is getting worse to it's time to take it apart.

My push on tee fitting is leaking at the stem going to fuel gauge, very little but enough I should fix. Wrapped with Teflon tape maybe 4 or 5 wraps. Buy another fitting or is JB Weld alright to use in diesel fuel?

The time has come to change the transmission fluid. Need to know whether I should do the full or partial flush. In leaning towards full flush, but that's me. I'd like to put atf4 in with a full flush. Dunno how to go about a full flush though. Also, while the pan is dropped, doing the filter, thought about band adjustment and the Chevy solenoid. Don't remember the part number for it. What else should I or could I do while I'm servicing the transmission. I was going to do the block off for the passage to get 2nd gear lockup capability too.

I know alot of folks have temp fluctuation but I think it usually swings low instead of high. I had this trouble a few months ago and fixed it with a new water pump but its back again. I just had the radiator cleaned and rodded but it hardly had anything in it. Its got another new water pump and I have ran two different radiator caps. I have 3 different t-stats and they all fluctuate the same, two are 190 from napa and one is a cummins 180. I generally see swings from 190-203 or so, usually cruising it stays around 190-194 but will jump up to 197-199 for a second then back down. That doesent bother me as im reading those temps from the ultra-gauge and I think those are fi…

Alright been messing with this for a couple of weeks. Started when it first got cold. Noticed my heat was not as warm as usual. I checked my radiator and it was about half gallon low. After I filled it up I drove it and the heat seemed to be better. When I got home I noticed some antifreeze on the ground. Looked up there and found it dripping from the drain plug. Replaced the plug which I might add is a stupid design and pretty much worthless to actually drain your radiator. Why cant it be a pitcock drain. NOOOO it has to be some nasa frickin design with an O ring that doesn't actually work after you remove it the first time. :banghead: Sorry !! Anyway it wasn't the plug …

My 2001 truck is currently in "temp storage" on my side yard. I've been starting it once a month for last couple years. During the month it sits, the OEM alarm is on and what ever else slowly drains the batteries. Last month I pumped out 2 year old fuel and put in new fuel with a shot of biocide. Thinking I should disconnect batteries or install a battery disconnect. Maybe I could just pull a fuse to stop batteries from draining. If pulling a fuse is good idea which fuse or fuses should I pull? Any other things I might consider?

I had some errands to run today and drove the truck. As normal the temperature came up and held steady at 190*. I stopped at the local station to top off the fuel and left the truck running.It was in the low teens here in Michigan today. I know it's colder in other states but.............By the time I had topped off and went in to pay the temperature had dropped to about 160*Why..........

I am wondering if there is anybody here with an exhaust brake on a 2nd gen with automatic tranny? Do they work good together? There are transmission controls available that lock the torque convertor while braking but do they only lock up in overdrive and drive, or in gears below that? I've been trying to cut through the clutter on everything that's available but not having much luck. Hopefully someone here can help me out. Also what's the best brand to be looking at? Thanks!

Has anyone ever replaced the bearing in the belt tensioner? is this something that can be replaced and if so who has the part number of the bearing? mine is starting to squeak and i figured that this would be the cheaper route rather than replacing the entire tensioner. thank you.

My tensioner started sqealing like a pig. I plan to replace it but was wondering what the torque is on the bolt and if it had been over-torqued, could that make it squeal? Thanks

Beginner question... adding to my birthday wish list. Terminal tools for wiring. What would you recommend.
