I'm sorry, but its somewhat difficult to understand the symptoms here with your description. If the engine speed is at or near 5000 rpms and the road speed is at 45 or 50 MPH, then the transmission is either in second gear or the transmission is slipping. The other symptoms are either a result or coincidental, but I don't believe germane to the first symptom.
 
I would first start with checking the transmission fluid level. On Chrysler built vehicles, the transmission fluid must be checked on a level surface with the engine at normal operating temperature and the gearshift in neutral. If the transmission fluid is low or too high, you will get slipping. If the transmission requires any fluid, use ATF+3 or ATF+4 fluid only.
 
If the fluid level is okay, there are a number of things that could be at fault, such as a sticking or inoperative shift solenoid, bad electrical connections to the transmission, etc. You may need to have someone retrieve the fault codes from the computer before anticipating any diagnosis or repair. Most Auto Zone or Advantage Auto stores will check the computer for codes at no charge.

Dusty

Thanks, Dusty. I think I mislead you regarding the tach going bonkers. The actual engine rpm is not being effected. The engine remains steady and smooth as silk. It is just the tach that shows an incorrect high engine speed and by putting the transmission into neutral, the tach drops back to the correct reading (around 3k) and the Dakota runs correctly for a few seconds - until the tach registers a high reading and then the dance continues.

I'm sure the trans wasn't in second beacuse that was my original excuse/sign of denial. But i did find a transmission place that does free diaognatic check. so i will start there.
 
Thanks Dusty

Okay. I think I understand now.
 
All the more reason to think you've got a vacuum leak.
 
Good luck,
Dusty

Sorry to be a pessimist, but I suspect they're going to tell you that you need a full rebuild.
 
Good luck,

Transmission slip when making a left hand turn by pwalk
Dec 15, 2008 (12:29 pm)

I posted this up before a couple of months back and I'm hoping for any help in a dx of this issue so I can take care of it. Any help is greatly appreciated.
 
2000 Dakota, 3.9 V6 2WD with an automatic transmission. The issue has been occuring for the last 2 years but rather infrequently. When making a left turn my truck falls out of gear.I usually handle it by laying off the gas and letting it shift down before coming to a complete stop. Then give it some gas and everything is fine again. I thought it might be a sensor but before I take it apart to replace the throttle sensor I just wanted to get a 2nd or 3rd opinion before "operating" on her. The truck runs fine and the fluid is good on it. With 130,000 miles on it I know I'm probably getting to the point where I may need a new ride sooner before later but I'd like to keep this truck around for a long time. Again any help is greatly appreciated.

You have a 42RE transmission.
 
First, verify the fluid level. The vehicle must be on a level surface, the engine at normal operating temperature and the transmission in neutral. A low fluid level will cause this symptom.
 
Check the Throttle Position cable that goes from the throttlebody linkage to a pivot shaft on the left side of the transmission just forward of the large electrical connector. Check for binding by moving the cable end at the pivot shaft. There should be no signs of binding and the pivot shaft should return to the rest position consistently each time its moved. There should be a small return spring on the pivot bracket. A missing or broken return spring is a common occurrence on older, high mileage vehicles, especially those exposed to road ice removal chemicals. The pivot shaft seals sometimes get hard and can cause the shaft to stick.
 
If the Throttle Position Cable and Pivot check okay, you might have a low line pressure problem. Draining the fluid and replacing the transmission filter might fix this, especially if its never been done before. Remember, use only ATF+3 or ATF+4 in this transmission only. Do not substitute!

Tranny slipping when going left by dudeman1
Dec 15, 2008 (7:26 pm)

My 99 Dakota 3.9 A/T keeps slipping when turning left, and even downshifts when going up a left hand hill. I put fluid in and went on a 900 mile trip for 2 months and returned with no problems, except the lake of tranny fluid after I got back from this long trip. I have purchased RTV gasket maker for the fluid replacement, but not sure where to purchase the specific fluid - is the dealership the only place to get guaranteed correct fluid for the tranny on this truck? I'm getting ready to go back on this 900 mile trip this weekend and want to know what precautions I need to take prior to making the trip. Any help would be much appreciated!

Your '99 was built with ATF+3, however ATF+4 has replaced it. You may use either. I have seen ATF+3 at Auto Zone stores. I know Chrysler licensed ATF+3 to Havoline or Valvoline, but I continue to use Mopar ATF+3 or 4 because I trust it.
 
Chrysler makes a chemically compatible RTV for Chrysler-built transmissions, it is Mopar ATF-RTV, MS-GF41B, #05010884AA. I've used other RTV brands in the past and all leaked eventually. Something in ATF+3 or 4 softens regular RTV.
 
Best regards,
Dusty
