On the high way it kicks down to second shifts to third and it feels you have an anchor tied to the bumper, let off the throttle and it seems fine.

Do you mean the 3rd accumulator capsule? Sounds like band is not releasing.

Any codes? What year? Recent tuning? 3-2 solenoid bad? History of trans? etc...

No codes, it was very intermitent until the trans went out. Rebuilt it and added the transgo reprograming kit. The 3-2 solenoid ohms out okay.

Did you scan for codes or is the SES not lit up? DTC in the trans will not always illuminate the SES.

If it doesn't do it during upshifts, only during 3-2 downshifts, I say something is causing the band to not release under high line since you say it gets better if you let off. Did you install any of the spacers from the transgo in the servo? Maybe it's too tight on the drum.

Ok, does it do this during the upshift or the downshift??? If it does it during the upshift, then its more then likely the band not releasing like stated. I would pull the servo out and make sure the pin is not sticking in the servo or in the case. I would also make sure you have enough band clearance, and all orings and seals are installed correctly. Was the spacer plate drilled correctly during the install?

hmm ok
on the 3-2 the 3rd clutch would need to release as the band applied. If the 3rd clutch did not release then you would not be a bind up but rather a return to 4th gear. 3-4 clutch and band = 4th gear unless its only happening in D position then you would have a bind up due to the overun clutch being on. Thats a strange symptom unless you have a cross leak of some sort thats keeping the 3-4 set on during the 3-2 downshift and bleeding into the overun clutch circuit at the same time. That would point to something with the stator or inputshaft rings/drum
