Seems to be sensor or computer related. Had a 10k machine on leaving a stop light she shudders my eyes go wide and I pull the shifter to first no change. At this point I think it's just slipping with a very light foot I get the load moving with minimal slipping.  

Ounce going I get 1upshift then lock and I stand on her roaling coal. Hunkered down and accelerating with no slipping.

It didnt hit me yet I was starting in second. 

Get where I'm going check fluid its good shut truck off . Go to lunch later no trailer truck sluggish to move then I realized it's in 2nd. Just for kicks I shut it off rolling to stop light turns green issues gone.

 

Ever since I've noticed it does do it on cold fluid. What I think is with fluid cold pressure must be high enough it's going into limp mode though no lights appear on dash wich I expected this truck never trips a service engine light. 

Another thing is I'm pretty sure overdrive indicator has changed color to a darker orange.

 

Not sure if I need a bigger resistor to mask pressure or bump back pressure a fuzz. Also not 100% sure that's what it is yet.

 

Doesn't do it ounce fluid temp starts moving the gauge at 80deg its stays under 80 for a long time.

 

Kinda just thinking outloud maybe I'm off on thinking it's in limp mode.?

 

Towing today. Fluid at 135 no issues

90is idle 150iswot. Yes resistor. No to tests.  No time for tests gota wing it.

Your gonna burn up that tranny if you don't. Something's not reading correctly and that is now starting higher.

 

Remember that stock PCM line pressures are 55 idle and 90 going down the road. I'm wondering if a resistor can fail and show true line voltage? @Mopar1973Man

 

Like if the voltage 5v the resistor should show 4.6v. if it fails does it show 5v thought it?

First drive across town. No 2nd ur 3rd gear starts 2-3 shift seems quicker. U have not drove it over 1/4 throttle.  

Headed back to shop after dropping of paper at morgage office. 

 

It do think it bumps into gear from at stand still not sure though.

 

Fingers crossed no more issues 

 

Havent had issues running more than 55psi since rebuilding a few years ago. 

 

3rd locked to overdrive 4th locked is quicker that's for sure changed. Shifts quicker than I can hit the button.  

 

Cruising at 80 trans temps at 80 86

 

 

 

90-100 for well put together tranny is nothing at idle.

90-100psi is fine, but it's not if you starting in 2nd or 3rd your going to have issues with burning up the clutches. 

 

It's too much to start in 2nd or even 3rd.

2nd gear starts seem to be resolved. Took me a couple weeks but I got it. Now I can do the turbo

 

Didnt get much chance to test her out today shes being yanked from job to job

 

 

Adding a few pics. To bad you never seen these billett parts hidden in tranny.
