I posted awhile back with some weird transmission issues in my fiance's 2004 1500 3.7L.
Finally threw a CEL and pulled the codes:
P0700
P0731- Gear ratio error in first
P1790- Fault immediately after shift
P0944- Loss of prime
P0876- Under drive pressure switch sense circuit

The issues she has been describing to me:
It hesitates to go in gear (sometimes)
It hesitates to shift out of first and maybe second (sometimes)
It "chokes down" at a stop (rarely)

and of course when i drive it, none of this happens so i can only take what she tells me and try to fix it.

Just 2 weeks ago i changed the fluid and both filters and added lucas stop slip. seemed to help for maybe a week.
The fluid looked and smelled good, and still does.

Can some one help me out with this?

 

When you changed the filters did you put the seal in first before you put the filter on?

 

Yeah i seated the seal first then bolted it in. I cleared all the codes and they have yet to come back up. But she stillsays its doing the same thing. Hesitating to go in drive and not downshifting for hills. Fluid still looks prestine....

 

check the trans fluid level I know for my 08 the transmission is sensitive to the amount of fluid in it 3% out either way and it has issues, but there is also a sensor on the rear diff that is in a housing that can collect moisture and corrode (that was its main issue)

has it thrown a P0900 by chance?

 

Reason #2,071 a Ram should not have anything less that a 5.7 hemi in it.

 

Oh you mean like how flipped up tow mirrors dont belong on anything less than a cummins....?

Yes fluid level is fine. Problem has been found. The underdrive pressure sensor i side the solenoid pack is the cause. Thanks for the help to the ones who helped...

 

Do, go on with idiotic statements. I'll flip my tow mirrors any which way I want, whether I'm towing or not.

 

^Oh, dear God.

The 2nd gen boys would rake you for that picture.

 

I will fight all of them lol
