Bird, With the after market kit on the tranny (or with my new tranny) you can lock up the torque converter in any gear with no problems (except you need to be out of the after market aux OverUnder Drive) so the exhaust brake can function just fine to really hold you back (not quite as good as a REAL Jake brake but pretty good.) It automatically unlocks the converter when your speed drops to the set point so you don't shudder and yank the rods out.
