Agree with the last comment to a point. Mine has had this problem since new. Just located a transmission mechanic worth his salt. He will be installing a "Sure Cure" kit. This increases lubrication, which eliminates the heat issue that causes this problem. While he's at it, he's installing a shift reprogramming kit in the valve body for better shifts. He's done several in the past. I checked his customers, and they were happy with the fix. If you ignore it, the torque converter will prematurely fail.
I own a 1999 Dodge 1500 5.2 with the 42re. I just had it rebuilt with a converter about 5000 miles ago, and I'm having the same problems with the lockup. I brought it back, and they hooked it up to the computer on the highway. The graphs showed a consistent drop in gas at the time of disengagement. He told me to put new battery terminals on. Tried it, still doing it. Told me map sensor, but everyone is saying it can't be? I think it's the TPS from the symptoms.
My Dodge at 105000 miles might be just worn out. Don't worry 24/24 warranty.
I have a 1999 Dodge 1500 SLT with 5.2l Magnum V8. I have not had any of these problems, but my speedometer does not work. I have replaced the sensor with no luck. When it stopped working, it had 167,000 miles on it. The only other problem I have is sometimes when I stop and release the gas pedal, it stalls and dies and will not idle for about 5 minutes or so... if anyone knows how to fix this please email me at firstname.lastname@example.org.
Hey, I have a 1999 Dodge Ram 5.9l automatic and my transmission won't shift out of second gear, and my speedometer is dead and my ABS and brake lights are on. I ordered a ABS speed sensor that mounts on the rear diff. I hope this takes care of it. If anyone had this same problem, please let me know thanks.
I have a 98 Dodge 1500 5.9l 4x4 that also won't shift out of second. Works better when you first start it and gets worse as it warms up. My ABS and check engine lights are on and my speedometer doesn't work until about 35mph. It doesn't seem like a tranny rebuild problem because it been like this a while and still works good when first ran in the morning. I've read it could possibly be shift sensors or ABS sensors. Any ideas???
I have a 2005 Dodge Ram SLT. On inclines on a cold start, when putting it in drive and depressing the accelerator, the vehicle rolls back at least 3-4 feet before engaging.
Hey, was searching around for some RPM info, and came across this, which may help you.
I own a 98 Dodge 5.2 liter truck. When driving and the air conditioner is on and blowing using the vent, when I push on the gas as little as 300 rpm, the air will stop coming out of the dash vents and will be directed to come out of defroster for windshield. As I let off the gas, it goes back to blowing air from the dash vent. It just started that after being in the shop at the Dodge place. I had just had a intake manifold gasket replaced, any ideas about what's going on?
There is a vacuum line check valve in the engine compartment on the right side of the intake manifold, try replacing that. It fixed the vent problem in my 2001 1500. Now I'll try some of the suggestions on the engine surging, the PCM re-flash and torque converter lockup and TPS sound like they fit the symptoms.
My 2001 Ram 1500 also had the surge problem, which got worse as the engine warmed up. It wasn't a problem below 45, but when I got on the highway it felt like it was slipping in and out of overdrive, especially when I went over a bump. I just replaced the throttle position sensor and it seemed to have stopped the problem. The weather is cool currently. I don't know how it will work in the heat of the summer, which seemed to have made the problem worse.
98 Ram 1500 4x4 318 auto. Have rpm jumping 300 rpms starting at 45 mph. Changed TPS 3 times and adjusted from .5v to 1.2v with no change. Changed oil and filter, adjusted band, checked all connections and grounds, removed check valve in line. Rerouted spark plug wires and still no change still jumps. Works best at .7volts. Thinking of changing switches and solenoids in trans. Open for suggestions?
I've got a 00' Ram 1500 and it shifts hard into 4th gear (overdrive). Sometimes it shifts into 4th around 38 mph and sometimes as high as 45 mph. It seems to be worse when it shifts earlier (around 38mph). So the hardness of the shift is determined on the throttle. Is this a problem with the tranny or TPS?
I have 1999 5.2 4x4. Had the same shift problem. Try adjusting the throttle valve cable; it helped me.
I just got a 98 Ram 1500. Drove it for 2 weeks, then it started making a whine noise in reverse only when it's cold. Goes into reverse just fine after about 2 miles. And just like many of you, I have the same overdrive problems. If you have got any ideas, email me at email@example.com
I have a 1998 Dodge 1500 5.2.. It will idle fine after starting, and then I just give it a little bit of gas and it does on me.. What could this be? Email firstname.lastname@example.org or 303-801-8937 Thanks.
Did you by any chance find the solution to this problem, because I am having the same one... Please email me at email@example.com with info.
It is most likely your throttle positioning sensor, which holds two screws under the air box.
I had the same problem, and it was a wire shorting in the shifter knob that controls the on/off of the OD.
There is a vacuum line that is on passenger side of the intake. It goes to the inside to the A/C controls. It is either off or the check valve is bad. I had to replace this on a 97 Ram truck, and a 97 Jeep Grand Cherokee.
I also own a 1998 Ram 1500 4x4 5.9, and I have talked to my buddy at work, and his buddy owns a garage/shop locally, and he told me that if your tranny fluid is burnt, then your tranny is junk. If it is not burnt, he suggested to replace the shifting solenoid first, and if that doesn't fix it, then replace the torque converter. I haven't gotten this far yet, but the next couple weeks I will do. If you do, this post results and I will do the same. REMEMBER, it is ONLY a suggestion that this mechanic said.
I had this on mine. Replace the speed sensor on the rear end. It was ease to change, and under $50 as I recall.
I have the same problem, any solution?
Trans was replaced, and does the same thing. Torque converter tested OK. I am leaning toward the TPS voltage. Wear and tear at 100k plus means that something is worn, and it has to be a dynamic part. Mine does not do this under load pulling conditions, IE, uphill or towing when you are on the throttle. And it only does it at highway speeds. Potentiometers go bad sooner or later.
