Transmission Problem

[MWikoff]

My Dodge started hesitating when going into second gear. Today it got worse. Then when I got into it today, I put it in reverse and put it into drive. It started reving up but not going anywhere. I coasted to the side of the road and it would not go into gear. After messing with it for awhile, I shut the truck off and waited a few minutes. I started it back up and it went into gear, only to drive a short distance and then the same senario. I pull off again and put it in park and shut it off. I start it back up and it goes into drive, only to drive a short distance and then just start reving up. I did this until I could get the truck back home. The transmission fluid level is not low, and no error codes.

Welcome to RF!

I can probably help you (or someone else can) but we'll need at minimum the year and engine size so we can determine the type of transmission type and could provide a diagnostic chart.

Anything else is just guessing.

2002 5.9..it's in the OP's info under his avatar...

I don't read side bars much. usually because it's not there...sorry folks.

That aside here's what the '01 manual says about the OPs 46re transmission. I understand that the vehicle will move once it's left sitting. If it will still go into reverse but not forward gears, use the first list. If you have nothing at all once the transmission fails, check the second one.

My first two guesses were govenor shift seleniod or something is plugged due to band or clutch failiure. Good luck with your issue.

I thought I replied to this but it wasn't showing up. There is no letting the truck sit. I just pulled off the side of the road, and turned it off and back on immediately. Goes into gear after this for a short time. I will recheck fluid tonight.

Being an 02, and that you posted in the second gen forum, i am guessing it is a 2500? and i believe okie assumed its a gasser, so just to confirm that you have the 5.9 gas engine, not the 5.9 cummins (different tranny) that being said i would lean towards exactly what okie said, even on the 47RE (diesel tranny) I had a similar problem right after purchasing my truck, hard shifts, delayed shifts, inability to shift, and replaced the governor solenoid and something else in the pan and it fixed my issue. can't remember off hand but i will try to check the receipt tonight. How is your fluid? is it burnt up or wore out? is there debris in it? what sounds is the truck making, be as specific as possible as none of us are there, so the more info the better

Loki 2002 1500's and some 2003s came with a 5.9 magnum. The 5.2 was dropped for the 4.7 in 2002.

Hey now...I already got yelled at because some specifics would have been nice.

Just checking the fluid isn't going to tell you much unless its dark red, black and smells like burnt toast. At that point you're screwed.

You're probably going to have drop the pan after you run a free test at autozone to see if there's a stored code.

Loki, replacing the govenor pressure selenoid and OD/Lockup selenoids on a 46re is a common repair. Coupled with a fluid /filter change, cooler/ check valve cleaning and a band adjustment might or might not make things last.

I am far from knowledgable on vehicles, but I will clarify on some of the details. It is a 2002 5.9 Magnum 2wd 1500. The fluid is light red, and doesn't appear to be burnt, and there isn't a smell associated with it(fluid level appears ok). I have a diagnostic/programmer and I will check to see if there is any codes. This problem started by the truck slipping when going into second gear. This went on for a couple days followed by the truck not wanting to go into gear at all. There isn't really any noise associated with the problem, just rev'ing of the motor until it shifts, or now the lack there of shifting. The odd part to me is that it will go into gear only after I turn the truck off and immediately turn it back on.

 

[Okiespaniel]

Part of the reason the slippage happens is either crap plugs your filter (when truck is running) and when you shut it off it falls to the bottom of the pan.
OR...the truck runs fine until voltage to shift your pressure selenoid gets too high. Then it defaults.

Here's my best guess until you drop the pan. The 2nd gear band is out of adjustment or the pressure selenoid is bad. The 2nd gear band is the only one you can see when you open your transmission up It goes aound the planetary drums (where your internal gearing is). It's function is to stop part of the planetary that low /reverse is in so the transmission shifts to 2nd. This band wears ****** if over or under adjusted.

The selenoid is a magnet relay . When you put the transmission in gear. an electrical current energizes it to pull valves open to put your transmission in gear with fluid flow.

That may not be perfect explanation for you ASE techs out there but it's correct enough for a layman.

When you open your pan up, you may find a lot of crap in the bottom of it (or none if the band didn't wear). Or you have an electrical fault in your pcm wiring, pcm, or selenoid. < repeating self here!

 

[MWikoff]

Thanks Okie. I will investigate further.

 

[MWikoff]

Ok. So I got back in the truck last night and checked the codes. There were two codes that I have had for awhile that I believe are unrelated to this issue. P1685 and P0455. This time the truck will not go into gear whatsoever. I did hear a high whining noise when trying to put it in reverse for a very short period, then no noise. Also ABS and BRAKE lights have appeared on the dash.

 

[Okiespaniel]

Codes...Thats either a ground or PCM issue.

Sounds like you're going to have to pull your tranny apart. I'm believing you have a fluid issue and the whining you hear is the pump and or bushings burning up with no fluid.
Time to get to know a good transmission man.

 

[MWikoff]

Alright, one last post and I am taking it in. I recorded this noise as I was re-checking the transmission fluid last night while the truck was in neutral(The noise I had wrongfully diagnosed as whining). It only makes this noise in neutral. Transmission fluid was full btw. Well NM it won't allow me to uplaod it but it is a buzzing noise while in neutral.
