 Subject: Y2K Dakota Tranny problems
IP: Logged
Message:
I have a Y2K Dakota Club Cab with the 4 sp AT. I have noticed that when there is a drastic change in temp. from warm to cold, that the tranny does not engage if you stick it in Drive(OD), If you put it in D1 or D2 it will go fine and after it warms up it will go in D3, but i seems like it is slipping. I never had this problem until I changed my Tranny Fluid and Filter. I believe that we put ATF+3 in, which I've gathered from the forum that it is the wrong flavor and I need the ATF+4. When it does this it also sets a DTC and the engine light comes on. Whenever you come to a stop at an intersection, the truck will not downshift,and it will stall, unless you put it in neutral. When this happens I drive the truck like a stick, so I don't make the tranny slip. After the truck warms up it seems to work fine, but it takes a couple of cold starts to make the DTC go away. Is this just a fluid problem, is it a speed sensor problem, or both?
Also
How many quarts of fluid to fill up the Tranny?
Thanks for the Help,

I Forgot to add that whenever I warm the vehicle up on a cold morning , say for maybe 10 minutes, I've noticed that this actually makes the problem appear quicker. Fluid level is good, I thought maybe it was pumping it all of the torque converter when idling.....
Thanks,

clean/check the speed sensor(s) first, then I would check into the governor pressure or transducer....
Tell me,,when you shift it into first does the truck engage really hard...almost like it wants to stop (sqeaks the tires)???? If so, it is your transducer....
If the vehicle stays stuck in second at stoplights it is the transducer or Governor pressure sensor....
MAKE SURE YOU PUT IN ATF+4 IF IT IS REQUIRED FOR YOUR VEHICLE!!!!!!

last_username,
Could you elaborate a little further on what you said here:
"Tell me,,when you shift it into first does the truck engage really hard...almost like it wants to stop (sqeaks the tires)???? If so, it is your transducer...."
When you say shift, do you mean when I initially stick it in gear, or when I the vehicle is downshifting and coming to a stop?
It warmed up about 20 degrees today (from 4 to 24), and when I when out at lunch it worked fine.
Could it be that the fluid is just the wrong type, and it requires more friction (viscosity) at the colder temps than ATF+3 can give???
Scheduled to get system flushed out and filled with ATF+4 on Tuesday.
Thanks,

I have a 2000 4.7 auto and my book says to use ATF+3. I've got 75,000 on the tranny with fluid and filter changes every 35k and no problems.

if it is stalling when you come to a stop that is an indication that the tourque converter cycling swith may me hanging up an keeping the converter locked up, which would simulate the same feeling like if you came to a stop in a manual transmission car without depresing the clutch. If this is the case it will also interferre with the way the trans upshifts and downshifts. If the TDc light illuminates there should be a DTC code stored in the ECU memory which may give you more insight as to the problem at hand. Overdrive on these transmissions in basically a system that locks the converter from its normall stall or slip which allows the vehicle to idle without bogging down the engine. When it becomes stuck in the locked position it is basically like a standard without a clutch

Well I looked at my manual over the weekend and it says to use ATF+3. I have read in a couple of places about using ATF+4. My tranny never gave me any trouble in the cold until after I changed the fluid and Filter...
One thing I noticed was that when I checked the fluid level the other day, she was clean, and did not smell like it was burnt, but it was really frothy, Could water in the fluid cause this?????
How it would have got there other than condensation beats me.....
I guess that is all pretty much irrelevant becasue I think she finally took a sh*t today.... It was working fine yesterday, but wit hthe cold last night she would move at all this morning...... Looks like I'll have to have it towed to the shop to get it flushed, diagnosed,etc...
Dang Power lock froze up this weekend too, no my driver door does not unlock, I think the motr got fried..... got 74k+ miles on it now, I hope it don't blow up when it hits 75k.... LOL The sad part is that I never beat mine, In fact you could say I baby it, probably a good thing I did not beat it, would have 2 years ago.
I was looking at getting a new Ram next year, but if this is the crap I am going to put up with they can keep them....

'00 45rfe calls for ATF+3. ATF+4 can be used, but is not recomended unless you do a full tranny flush at the time of conversion. I was going to convert my '00 tranny to ATF+4, but was advised if I didn't do a tranny flush to get out all of the ATF+3...1, I wouldn't get the benefits or ATF+4 and 2, at the time they suspected some interation problems. I stayed with ATF+3 and I tow and plow snow. I've only changed it twice in 80K miles. The tranny is the only thing on this truck that hasn't given me a problem.....YET. ATF+3 is fine. ATF+4 is better because it is synthetic and should last longer, but if you have ATF+3 in your '00 tranny you shouldn't have a problem.
I know you said you checked the fluid level, but it certainly sounds like low fluid level or something is up with the filters.?

Figols,
Talked to a couple different folks , and I get a couple different stories..... Possible causes that were given to me were the following:
1. Bad Fluid, Needs Flushed maybe bands tightened
2. Torque Converter
3. Bad internal seal
4. Speed Sensor
When I shift it into gear it kind of goes in, but truck will not move (unless it is in Low and I mash it). I don't hear the solenoid kicking in when I shift it into gear..... any ideas.....
My buddy has a Jeep and a very similar situation as to what is happening to mine, and he had the fluid flushed, and it works like a charm now...
Hoping this little dose of warm weather will maybe help the fluid viscocity, and it will engage tonight, then I'll take it in. If not I'll have er' towed i tonight....
We'll see what the verdict is then

There are no bands to adjust in your 45RFE.
Proper fluid to use is +4. In '00, the other transmissions still called for +3, but 45RFE called for +4. Then they started recomending +4 for everything. Serviced mine with +4 and no problems, but I believe that's also what came in it.
This tranny should be fine in the cold - one day at minus 11 here this week and mine runs flawlessly. While your symptoms may be worse in the cold, that's not the root cause - I think you know that though. Good luck, please let us know when you find the cure.

Well I had to have it towed into the Dealership this morning......
Their first thought was that the Flush would not help it.... so it is $60 to just take off the pan look around and put it back together.....
I will post results after she gets into Post-Op

Well I talked to the dealer several times yesterday. I suggested flushing the transmisssion and refilling in with ATF+4 becasue my friend had a Jeep with the exact same problem and the flush fixed it and it is still running today.The service Manager suggested the flush would not fix the problem since the truck would not move for more than 2 feet on its own. He recomended tearing off the pan and having a looksy inside. After looking inside, His mechanic said that the fluid looked good and that there was no metal inside, and that must be something broke deep inside, and it would need major repairs.
After talking to my brother who is a real mechanic
I left a message for the service manager about looking at DTC codes, but they never got back to me. My Brother also suggested using some seal conditioner because the seals are known to have problems.
I stopped over the Delership after work yesterday and I was going to put some conditioner in, but I thought I'd try looking at the DTC codes, and see if I could pinpoint the cause of the problem. Well when I went to check the codes there were none showing, so either dealer cleared them, or they cleared themselves.
To make a long story short, I figured I'd see if the transmission worked, so I started working through the gears, and much to my surprise the transmission immediately shifted into Reverse and I heard the Solenoid clicking away, Then D, D2, and D1. I then proceeded to move the vehicle both Forward and Reverse and it worked flawlessly, mind you the temp was pretty cold here last evening.
The sad thing is there was a lady there with a minivan that had the same problem, and they were going to soak her 2k for a Chrysler reman, this service manager needs to learn the first rule of thumb, and that is the customer is always right....LOL
I am going to put the Dakota on close watch to she if she starts acting up at all...

Well Everything is back to normal!!!!
Had them Flush the Fluid out and Replace the Filter, Then had them Flash the Tranny with the TSB update.
Shifts way better now, and when I towed with it this weekend it did it nicely and the shift points are much better now....
The diagnosis of the problem seemed to be a problem with the way the filter was in against he on seal, or the filter itself may have worked it self loose a little and was not seating tight against seal. Either way the problen was causing blow-by which explains the frothy fluid, and also the low prsseure fault code (P1762).
Thanks for all of the help and I hope this inf ocan help someone else out...
