ok, put new gov in, its a sonnax #730, springs r way liter then stock ones. i had also loosened the tv cable 3/8" + 4got i had done that or i would have moved it back. cause now not sure which one helped the most. pressure is all down to bout 120psi. it shifts 1st to 2nd an starts to slip, so i stepped on it an
it caught just fine. same with 2nd to drive an drive to overdrive. but D to OD was too quick. then from OD back to D, have to floor it even only going bout 25 or 30 for it to up shift. it will chirp tires 1 to 2 and 2 to D, but 2 to D is pretty hard shift. then D to OD is too quick. i know the way i had the tv valve set with pan off, it was all the way opened at WOT. so now its 3/8" from full open. the more i drove it, it seemed to get better. took it for a mile +. it sure feels like converter was slipping, but then again what do i know. guess cause i got lucky with my 1st tranny rebuild that i was smarter then i am.Thanks again for any more advice.
