2005 150p SLT 4.7 v8 "kicking" at 40-50 mph

[Miqroro]

My 2005 1500 SLT gas 2wd has been "kicking" around 40-50 mph for a while now. Can't remember how long. My foot is lightly pressing on the gas when it does it. Feels like the truck is shifting gears almost. Like bucking. That's the only way I know how to describe it. Issue is intetmitten, doesnt happen all the time. But a good chunk of the time it does.It's at 127,231 miles. New water pump, new serpentine belt, and transmission flush done at 126,181 miles. Spark plugs were changed maybe about a year or more ago. Can't remember. Oil changes done like clock work, go to dodge ram dealership. Using same gas station. Air filter changed December 2017. TP sensor just changed last week, my mechanic thought that might be the fix but still having the same problem. Next he wants to possibly put new spark plugs. Has anybody else had this issue? I'm lost here. Not sure if it really is the spark plugs. Also, the RPM's only seem to jump maybe a centimeter when the truck makes this motion. They don't go do much when this happens. Somebody please give me your thoughts.

See my post. Has same thing going on no codes. Going to the dealership for thorough diagnostics today. I think mine is transmission related.

If it's not engine related could it be torque converter?

Our 2007 Jeep Liberty "shuttered" at those exact speeds when applying the throttle and the transmission shifted into overdrive.

Turns out the torque converter was warped and a new one fixed it. That was back at 124k miles. Jeep now has 170k on it.

@Arth @john p f My truck has no codes popping up either. I don't wanna shell out a bunch of money to my mechanic for testing/replacing/fixing different things and none of them resolve the issue. My cousin thinks it's the transmission too. I know my dealership would charge an arm and a leg. This morning driving to work on the interstate I was going about 60 and it kicked just a tad bit which is odd because this is the first time it's done that at this speed especially on the interstate. So you think it could be the torque converter? I'll have to check into that! @Arth Do you have any idea what could cause the transmission to do this? I'm gonna read your post now.

I already replaced all the little things that probably needed replaced anyway that a dealer might have thrown at it. Spark plugs, throttle body, weak fuel pump, gas cap, grounded the throttle body, greased up the dry pcm plugs, even changed the transmission fluid and filters. etc... easily several thousands of dollars of dealership work. However I don’t want to replace the transmission or torque converter without seasoned professional Dodge experienced diagnostics.

 

[john p f]

However I did run across this transmission rattle that is inaudible while driving.


Very likely just a bad solenoid. $180 Oreilly part plus $200 core. But Sounds like a bad transmission or torque converter.

Honestly I don't know what caused it and I can't remember if we had any check engine light codes. I don't think we did. Personally I think it's a design flaw at least for my liberty's transmission. It's a 4 speed that acts like a 5 speed by waiting to lock the torque converter after shifting into 4th. Sometimes it will do it after shifting into 3rd and the RPM's will drop like it's a shift but it's not.

Ours did it once it made that final shift and we were giving it some gas to accelerate and was consistent.

If your mechanic change out the throttle position sensor and he thought it was it.Where I come from is called a parts changer .The only good thing about a mechanic at a Ram dealership is that part doesn't work he can take it off and put it back on the shelf and you are not missing a thing .Now if you buy it from them or a parts store it doesn't work most likely you own it because it is electronic.I don't have a idea what name brand plugs you put in your truck but most Dodge Rams they ask for plain old Chanpion copper core don't ask me why but all the Dodge aka Ram calls for them.As far as your transmission it could be solenoid.Also you had a transmission flush if that transmission hasn't been flushed on a regular basis with all the miles on the transmission a lot of times the flush causes problems.If you might think it is your transmission take it to someone that specialize in transmissions instead of just someone who can turn a wrench.I can mechanic on most stuff but I'm also called myself a Jack leg mechanic I know stuff but not everything.

@fastf exactly! A parts changer. That made me laugh. That's what I'm scared of. I feel like that's what he's gonna do to me. Gotta be honest here, I'm 26 year old female. I know nothing about vehicles. I'm trying to learn and do my best. My cousin usually does all the work on my truck but he doesn't know everything. He doesn't know much about transmissions but he has a feeling that's whats going on with my truck. I don't wanna replace my spark plugs again and pay my mechanic to just tinker around with my truck. I pay for everything on my own and I can't afford for somebody to just guess at what "could" be causing the issue. Gonna call some actual transmission places tomorrow to see if they can hook up a computer to the truck and see if they come up with anything. Actually gonna make my cousin do it for me, I get scared that I'll get taken advantage of since I'm a female. I just wish it was easier to diagnose this issue. My old Ford ranger 1999 had this issue too, it had over 100,000 miles on it as well. @Arth I'm going to look up solenoid, I've never heard of that before. And I'm going to watch that video you posted. My cousin tries to teach me everything he does on my truck so I'm learning very slowly. I appreciate all the feedback you guys have given me. Any other thoughts I'd love to hear.

So my mom has a 1992 f-150 and her truck had the same issue as my 1500, she had her solenoid replaced by my mechanic and that fixed her truck. Not sure if hers was "kicking" at a certain mph. Wonder why he didn't suggest that for my truck?

 

[Miqroro]

@john p f that video won't play, says it unavailable. I'm curious where the solenoid is located on my truck. Time to do some research and learn.

 

[john p f]

YouTube was down earlier I think it’s back up but the solenoid pack is located on the valvebody inside the transmission. The giant electric plug actually attaches to it. Had 2 Ford techs say that they see similar things with bad MAF mass airflow sensors and no codes.

 

[fastf]

He may fix it who knows .I know the feeling not having the money most the time.My wife had 3 surgeries since the end of September and been out and in the hospital and out.I have worked on Motorcycles and cars and trucks most my life but when it comes something I don't have the tool or the equipment to do the job is when I look for a shop that can being a female should not stop you from learing how to repair or take care of your truck.There are females in this forum that can run with the best man in here as far as working on their stuff i have talked to them.Go out and buy you some desent tools and get you a repair manuel for your truck and read and learn you have to start from somewhere then you will know what these parts changer are doing.

 

[Miqroro]

@fastf I hope your wife is doing better! I watched some videos on YouTube about the solenoid. I do need to get a manual for my truck. I just have the one that came with it when I bought it. I love my truck and I want it to last as long as possible. I'm trying to take care of every little thing now before it becomes a big problem. Thank you for your words of encouragement!

 

[Miqroro]

@john p f mass air flow? That's another thing I'll have to look up as well. You guys are sure giving me my homework! Lol I appreciate it so much. Watched a few videos on YouTube about the solenoid. I think it might be worth a shot to have that replaced on my truck still.

 

[Miqroro]

@john p f I saw on another site that the dodge 1500 2005 4.7 v8 doesn't use a mass air flow sensor but it uses a map sensor. Do you know anything about this?

 

[fastf]

The sensor it attached to the front of the intake manifold there are two plugs one is the water temp and the map sensor.You will need a socket that will be able to unscrew the sensor the socket is used to help remove the o2 sensor on some cars cost about 10 bucks somewhere around that.Hope this helps.

 

[john p f]

The 5.7 MAF mass airflow sensor just hand twists in or out of place if the wire is disconnected. Very easy. Sounds like the 4.7 is still fairly simple as fastf stated.
How many miles are on your truck?

 

[john p f]

5.7 MAF



I guess this is actually an IAT. Intake air temperature. I thought it was a MAF

 

[fastf]

That aint where its at on a 4.7 it is in front of the intake manifold your water tenp sensor and the map sensor next to it .The best way is to find it is look between the altenator and the air pump look down and there they are you will need to un plug it and use a deep well socket and a extention to get it out.That picture showing isn't on a 4.7 .
