I can probably help you find out what's wrong with your Dakota, but first I need to know a couple of things:

  1. what exactly is(are) the code number(s)?
  2. do you have and know how to use a volt/ohmmeter?
Customer: replied 1 year ago.
Po 700. And po 750. Yes I know how to use an ohmetet. The code comes back as b solenoid fault. The tranny also has a buzzing sound when in park and neutral
Expert:  Juan Crespo replied 1 year ago.

thank you for that information.

Most likely, the problem is a poor connection. Give me a couple of minutes to find the diagram so I can show you where to test. Be back in a bit.

I AM STILL WAITING FOR THE DIAGRAM YOU SAID YOU WOULD SEND. 04 DODGE DAKOTA. NO 1ST GEAR OR OVERDRIVE. STUCK IN SECOND. CHANGED SOLINOID PACK AND SPEED SENSORS. STILL NO DIFFERENCE. WHAT ELSE COULD IT BE?
Expert:  Juan Crespo replied 1 year ago.

I'm sorry. We had a power failure and most of my equipment is down. I'll opt out so others can help you.

good afternoon my name is ***** ***** I will assist

I would suspect a wiring harness issue. you have replaced the hard parts. did you inspect the wiring for any damage???

Customer: replied 1 year ago.
From what w understand, this happens quite often. Where exactly is this harness.
Expert:  roy replied 1 year ago.

it is the harness from the transmission to the solenoids inside the trans. there is a connector at the trans that meets to the body harness. the rest of the harness is inside the trans.

Do I check these with ohmeter to check for continuity
Expert:  roy replied 1 year ago.

yes, you could. I would visually inspect first to verify no damage to the wiring.

That has been done what else could it be? Could the pcm be bad, we are not getting any errors about the pcm
Expert:  roy replied 1 year ago.

what has been done???

Roy

Customer: replied 1 year ago.
Visually inspected the harness and ohmed it
Expert:  roy replied 1 year ago.

ok, you need to verify 12 volts to the solenoid and 12 volts on the return wire to the pcm. if you have voltage back on the return wire to the body harness, then you need to verify voltage at the pcm so it is seeing the signal. if all that is good, it is possible the pcm is the failure
