First just want to say that forums like this are so helpful and wanna say thanks to everybody that contributes because sure has made it easier for me to work on my Dodge.

So, check engine light came on, would go up to 2500 RPM's before shifting from 1st to 2nd and was a pretty hard upshift. Was getting codes for pressure sensor and solenoid. Changed fluid and filter, installed new borg/warner solenoid and sensor. Test drove, still getting to 2500 RPM's before shifting, but not as hard a shift as before. Check engine light still on, but when I checked the codes this time, getting P1751 (Transmission throttle valve position minimum range performance) and P1754 (Transmission throttle valve actuator stuck). Took off the TTVA and seems to move freely. Put it back and waited the time for calibration as well. Not really sure what my next step should be except for changing out the TTVA. I don't have any way of checking the 48 degrees it should be moving. Feeling like I'm hitting information overload... but want to be able to tow my 5th wheel soon. Any insight would be helpful.

Thanks, wit.

Might take a look at this if you haven't done so already.

 

yeah, I have. thanks.

 

so, got my new ttva in today. put'er on and waited........

shifting like it was supposed to. threw some black smoke too, was afraid to before.

still have to wake up and drive it to work, hoping I'm not dreaming.

 

I would check the band adjustment also. Just another weak link in that transmission.

 

actually gonna do that, gotta find a inch pound torque wrench first. every auto parts store around here was sold out.

 

well, wasn't a dream. shifting like it should, was at the disc golf course, started the truck and lo and behold.... no check engine light.

woooohoooooo!
