wont shift properly help

[gallis95]

Changed governor pressure sensor and solenoid.. did a tranny flush..

It will shift up if i let go of the gas pedal but it doesnt shift if im on the gas... the truck can downshift perfectly but it just wont up-shift until i let go of the gas pedal

its a 2000 ram 1500 4x4 5.2

any help would be appreciated

Transmissions are not my strong suit, I'll be the first to admit, but have you tested or recently replaced your TPS sensor?

I prefer to use the Dodge FSM for troubleshooting and repair. I just can't attached that info for you until possibly later this evening.

This test can also be found in the 2001 fsm page 1538.

Edit: Also see page 2232 for info on setting the TVCable

if that don't work......shift solenoid, govt pressure solenoid is in your future

I already replaced those two sensors... like 200 miles ago... i tried doing the tv adjustment but theres too much slack in the cable so adjusting it doesnt do much

 

[gallis95]

i just checked turns out the throttle valve spring near the trans was disconnected.. SO i reconnected and the truck shifts almost perfect.. at 90 percent throttle itll shift perfectly downshift or upshift its good.. but 100 percent throttle it doesnt shift.. it revvs past redline.. please help me fix this.. let me have a perfectly shifting truckkk.. help a dodge brother out so

Sounds like your TV cable needs to be loosened just a tad.

loosened? should i just keep trying new adjustments until it works?

So far i've done a band adjustment, a tv adjustment, two fluid exchanges, one filter replacement, governor pressure sensor and solenoid replacement, and an output speed sensor replacement.... You seem rather knowledgeable, why would the limiter not work? and the actual throttle cable is a bit loose is there a way to tighten that? maybe the throttle and the tv cable need to be matched?

 

[gallis95]

Tried Tv adjustment again and it still doesnt work... someone help me.. TRUCK shifts at partial throttle but wide open throttle it doesnt... ive done a few adjustments but it doesnt make a difference.. truck drives like it has no limiter what can it be? HELPP!!!!

 

[Merc225hp]

You have done all that work and it still does not shift at wot, and the fact it was driven without the spring off the tv cable tells me its time for a rebuild.

 

[dodge dude94]

Is it slipping at all? How is it shifting under light throttle? What speed does it shift into OD and lock up at?
