Transmission or TC problem? I have had my fuddle 3400 stall and RockON transmission installed for about 5 months now and out of no where im getting some horrible slipping or more like complete release at high rpms and hard acceleration. if i give the gas 90% or higher around 4500-5000 rpms somethin slips out and it just revs up to 7000 or whenever i let off and does not shift into second gear. same thing happens if im cruising and it wont shift into 3rd gear from second if i gun it. Fluids are fine...if i go easier on it everything is fine. sound more like a torque converter problem or Transmission both are new so im a bit PO'd.
You left out a third "T" which is "Tune". Presumably
there was some done about the converter swap?
There are things that could produce this behavior
such as upping the max line % limit without removing
a crazy high value in the 100% column of the force
motor table that forces a big cut in line pressure at
high load. Perhaps the trans shift learning finally put
you over the line. Or something.
Do you have the means to inspect for this? Any way
to log commanded pressure and force motor current?

No i do not it hasnt been tuned since the transmission install, I hope you are right you seem to know what your talking about. Theres a local shop that does dyno tuning. You think i should bring it there or would i need some kind of on road tuning like hptuners/ls1edit?
