Hello

Thank you in advance for any advice/ Input, it is appreciated.

I have a 1998 ram 1500 5.9L 4x4 sport about 280xxx mi

I just rebuilt the 46re and everything was working perfectly for about a week maybe a little longer. I was gonna try the mountain and my 4x4 vac lines ended up being switched I realized after a little investigation. So I switched them back and now my tranny will not shift up from first in 4x4 or 2 high, still the same.

Did some research and tried pulling my 8 pin connector and manuel shifting, and I have some weird results that I'm not sure how to interpret.
With the 8 pin connector unplugged, I can manual shift from park to reverse and drive ( this is not an issue with the connector plugged in ),

So I start in 1 and upshift manually to 2 but I did not notice a shift then I went to D and and it shifted.

I turned off o/d and felt the downshift when I went from D to 2.

Like I mentioned every shift was working flawlessly before I went under it to fix the 4x4.

I'm not sure what to make of these manuel shift results. Any help would be welcomed thank you again

Also I should mention the first run f was check fluid and it was low so I added 3/4 of a quart and it.was.square.in the middle of the cross hatch and was checked in neutral running after being brought up to temp

 

O/D off button does nothing when the trans is unplugged.

Is your shift linkage properly adjusted? Is the PCM throwing any codes? (It likely is now, after unplugging the trans.... ) Does the speedometer work? Clear codes, take it for a drive. See what happens.

 

Yes the speedometer does work, I will borrow a reader today hopefully, does it need to be a specific type for trans codes ? I know my buddy had a basic one. Thank you

 

Pretty much any scanner will do. They are P codes, so almost all of 'em will read 'em.

 

Success! So I got my buddies reader and of course it was trans temp high Governor pressure a couple of trans mission codes and whatnot I cleared everything and plugged into eight pin connector and is now shifting as designed nice and smooth again. Thank you for helping. I did get a look at the APIN connector wire harness and there's some wire showing . I'm not sure exactly what the problem is codes or the plug but at least it's not internal thank you again

 

Yeah, the wires like to pull out of the connector, fix that, you REALLY don't want them shorting together.
