This might seem quite like an incredulous implication, but how old is the battery in your Dak?

When you say that the "...delays upshifting from 1st to 2nd..." do you mean that your getting an upward flair in engine RPM before it engages second gear?

Dusty,
 
The battery is less than 6 months old. It's as if the transmission controller got into some anomolous state. I'm not sure if I was in a "limp" mode or not, since I don't know what the "limp" mode is like for a 45RFE.

HELP ME!!!! by kfay

I am new here and i need some help. I have a 2000 dodge dakota 4.7Liter quad cab v8. I am having problems with my transmission. When I start it cold, the transmission will take a while going into reverse or drive. When you drive it for awhile there is no shifting problems. The engine light comes on and goes off after awhile also. I am hoping I do not have to get the transmission rebuilt. We took it down to check if any codes came up, which they did. I don't remember the codes, but they were something like 4710,1-7, don't quote me on that though. Can anybody give me an Idea what it could be?

The "Limp-in" mode for a 545RFE provides hydraulic control only and will permit reverse, second, and third gears only.
 
Did you check for an open IOD fuse? If this fuse is open the transmission will operate normally for a while, then cause the transmission to go in to limp-in mode. The IOD fuse supplies memory keep-alive current for all vehicle control modules when the ignition switch is in the off position. Your symptoms are very common for an open IOD fuse.
 
The IOD fuse is cavity 12 of the junction block on the left side of the instrument panel in the 2003-2004 Dakotas.
 
Best regards,
Dusty

What is the mileage and the transmission maintenance history?
 
My first suspicion id a clogged transmission filter and/or low transmission fluid.

I agree with Dusty - the automatic xmission on the 2000 4.7L was speced to have frequent fluid-changes.... later model-years changed over to synthetic fluid in the xmission which reduced the frequency of fluid-changes.
 
You may want to consider a full and complete xmission service including all filters. Also consider using the synthetic fluid of the 2001+ xmissions. (ATF+4)
 
Make CERTAIN that only the proper DODGE xmission fluid is used. Using any other fluid (like dexron) can really mess up a Dodge xmission due to the different clutch friction the wrong fluid imparts.

Well, if this is the first transmission maintenance its possible that oxidized and dirty fluid has partially clogged the anti-drain back valve or the lines.
 
A cold start delay in to gear usually indicates low pressure.
 
Do you know which transmission you have? Either a 545RFE or the 46RE.

Dusty
