Archived Quick Help wont shift

[pholt]

I have a 2001 2500 4x4 automatic with 125k. This truck is pampered, I have not drove it in a few days and it will not, NOT shift into overdrive, Checked the transmission fluid it is fine, and clean as it can be, no burn smell??



What is up all of a sudden? This truck has never pulled over 6k?

Just to do this all of a sudden, it will not shif into OD>>>>???

 

[pholt]

You know it also seems the Torque Converter might not be locking up????

Other things wrong?

Does your speedometer work? I'd guess throttle position sensor or vehicle speed sensor, or maybe a burnt fusible link. Some year trucks the OD solenoid circuit was always powerd via a fusible link (just ask me how I know this ) and the PCM just grounded the circuit to engage OD. I'm not sure about your truck but most years had a high temperature cutout and a low temerature inhibit so prevent OD operation if engine coolant temperature was below 100 F or if transmission temperature was >230 F. Is it possible one of these sensors has failed? Hope this helps. Ken Irwin

 

[pholt]

Yes it does. I have a buddy that used to work as a Dodge and he said see if it takes off in second, and it does, that is why i thought the tc was not locking up. The truck takes off in second gear, and will not go into od, he says this is limp mode. Help what do I do where is the fuseible link? What should I do first. I have no trouble codes.

 

[pholt]

should I just take it to the dealer and let them plug it in?

Fusible links

Fusible links are located next to the DS + battery cable. I don't have the service manual here (I'm at work) or I could help you with finding them. It doesn't sound like a fusible link to me though. That wouldn't put you in the limp in mode as far as I know. Some event put it in the limp in mode. The dealer should be able to tell what caused it with his scan tool. That's the first thing you need to know. There are other places that can read the codes but the dealer will normally do this for me for nothing. I spend a lot of money in their parts dept. It depends on your relationship with your dealer's service dept. Ken Irwin

Possible solution

Try disconnecting both batteries for 15 minutes and then take a test drive and see if it works correctly.

I just called a reputible transmission shop, he said it sounds like the govenor sensors in the valve body?? But who knows this transmission BETTER not be out. I will chunk this Dodge and never buy one again, this truck is pampered. Oh well I am dropping it off in a minute and let him scan it.

 

[pholt]

He said this is caused by metal shavings in the pan, oh I dont like the sound of that. I refuse to belive this transmission is bad, there is no way.

 

[pholt]

I am going to do that right now before I take it in. I just spent $1500. 00 on the front end and a grand on tires, my patience is wearing thin. .

Look for the simple things first

Don't jump to conclusions. The simple things need to be checked first. I doubt the transmission failed while the truck was "sitting for a few days". Check for simple things like a mouse chewing on the wires or moisture in the transmission connector or corrosion on the battery cables. Transmissions rarely fail mechanically while they are sitting still. Not saying that it can't happen but I wouldn't go out and buy a new truck based on the symptoms so far.

 

[pholt]

I unhooked the batteries no luck. It still took of in second. It is at the transmission shop now, he is going to plug it into the computer, he says he see's a lot of Govenor sensors go out and do this. Anyway I should know this afternoon. I also checked the plugs, cleaned the cables, no luck. I will post what he said. Thanks for the help I will know soon...

If it will not come out of limp mode, it could very well be the governor solenoid. is it starting in 2nd or 3rd? That is key. if you manually put it in 1st(don't touch the throttle), will the truck move at all? if not, sounds like 3rd gear starts, which could be faulty governor solenoid, or no power to the transmission from the transmission relay in the PDM on the driver's fender.

You could pull the relay, and jumper the contacts, to see if overriding the PCM control over the trans relay allows first gear starts.

 

[pholt]

Where were you last night Fred??. But thanks for the help now anyway



No it WILL NOT start in 1st i tried everthing, but yes it does definatly start in 2nd. I dont think it is in 3d. I can pull it down in 1st and it really is in second because I can run it up to 2500 and move it to 2nd and it does nothing, but go into drive and it shifts, but no overdrive, it is second gear for sure.

 

[pholt]

Ok, Fred and Ken Transmission shop called, said the code was shift solinoids, the govenor solinoids in other words. And sorry Fred he said it is taking off in 3rd.



He said one of two things they just went bad, or trash aluminum, metal particles stopped them up, and the transmission is wearing something. Ok, HE told me $320. 00 to put new ones in and flush and fill the transmission is that ok? And I am going down when they pull the pan, how much particles is OK, my fluid lookes like it came out of the bottle. I AM NOT PUTTING A TRANSMISSION IN THIS THING I will trade it into Dodge and let them have the problem back. Please advise I am going down there soon, so I can be there when they drop the pan. And they can have it done today, who hoo another $300. 00



Thanks a TON Guys.

 

[pholt]

I really love my truck and want to keep it, but how much particles is too much, I dont want a headache.

 

[Fred Swanson]

Sorry, I was finishing a clutch and fuel leak on a friends 94 12V, otherwise I would have responded sooner.



The Governor Solenoid runs around $100-120. transducer is another $75(if he is not replacing that, he ought to). Not sure of his labor rate, so typical transmission service, 1-2 hours booked, plus the repair on the solenoid. It's easy to get to, so the labor there should be minimal, again, if he is going by labor rates, $300 is in the ballpark. The transducer is attached to the same aluminum block he has to drop to change the gov. solenoid.



And yes, they do go bad, ask to see the old one. If it is plugged on the top screen area, then there is material in the trans floating around. How long ago was it last serviced(miles not months).

 

[pholt]

How about never,,, am I bad??

 

[pholt]

The dealer did it along time ago, under warranty.

 

[Fred Swanson]

Oh, don't get me started. Yikes. 120K+, that's not too bad. I had a customer I built a transmission for, that never changed it in 3 years, 80K or so miles later, he calls, it's acting funny. He brought it over, I flushed it a few times, and he is back on the road.
