Heading out to run errands this morning and my tranny won't shift out of 1st gear.  It shifts into and out of forward and reverse but I only have first.  Where do I start checking things. I'm heading out to give it a look.  Maybe an electrical connection?

 

Thanks for any help.

No codes from OBDLink & no cel

Try selecting the 1st or 2nd gear positions see if it does shift up. If not I'm going to assume either a governor pressure sensor, governor pressure solenoid, band adjustment, or valve body issues.

I did drive around in the neighborhood trying that will the same results. 

 

To expand further, yesterday I replaced my fuel canister drain valve and put a big line kit on from filter to IP.  Could I have knocked anything loose when i was in there but It ran fine after I did that and test drove it.  Is there any vaccum used for the tranny?  Just throwing stuff out.

 

I will check FSM & any troubleshooting help would be greatly appreciated.

 

Thx

Just the throttle valve cable that all. There is no vacuum per say to the transmission maybe to the transfer case for CAD unit but that's it.

Thanks.  From the FSm It looks like the first symptoms at the top of the page.

 

 

FSM pg 21-166.pdf

Went for another drive and noticed something but am not sure if it's normal or not.  When I have it in first gear it feels like the tranny runs with a more solid (engaged) feel.  When I shift to 2nd or D it feels like it is slipping more but will remian in first.  Is that normal or not?

 

I checked fluid (but not quite warmed up and is in the safe zone).

 

IS there anything in the FSM for testing (other than with a DRB)?  I'm having a hard time locating any tests in it.

Have the sensors in the tranny ever been replaced? As Mike stated governor solenoid, pressure transducer and band adjustment. Cascade has a whole kit. It is recommended to replace those sensors whether they need it or not every 50k miles.

It has 80k miles and all orignial.  Will look into parts.  Are they parts I can change myself?  Looking at electrical now.  Good thing I have Monday and Tuesday off from work.

Yes, easy enough, just messy if you have the stock tranny pan without a drain plug.

That is a great vid.  Thanks.

 

Finally got the truck up to temp and I was able to get it to shift into 2nd.  I had to get it up to around 2300 rpm to shift.  Correct me if wrong but that looks like the problem.  I will get a new sloeniod & transducer.  Good time for a fluid/filter change as well.  I just have to wait for the boss (aka wife) to get home so I can run out for parts.

 

Thanks again for all the help MM & CT

Might be tough to find the good parts locally, not to mention price. Make sure you get oem mopar transducer and upgraded borg warner solenoid. Best bet is to order online, unless you can find locally, my 2 cents.

That was my next question.  NAPA parts are no good.  I am assuming where I am that I can only get good parts at dealer and spend a small fortune.

 

These are the parts you recommended?  Great prices

I will get in touch with them about making sure I have them first thing Tuesday.

 It would be a good time to adjust the front and rear bands too.  The rear band adjustment is only accessible with the pan off. Remember, tighten the bands to 72 inch-pounds NOT foot-pounds, don't over tighten the pan bolts (13 foot-pounds) and let the trans drip for a while before sticking your head under there. 

Was planning to adjust the bands while I was in there.  I will find the post on adjusting them.

 

 I probably will have to wait until Tuesday if I can't find good parts locally.  I am planning to drain it tomorrow and let it sit until the parts come in.

 

Thx

This looks like the beest thing to get.  All Inclusive.

Thanks for all your help guys, the SilverMoose is a happy truck now.  All things went well and what a difference adjusting the bands make.

 

Thanks again
