Torque converter failure or transmission failure Do converters fail often, or is it usually the transmission?
Yesterday I jumped on the freeway and got in it pretty hard, everything seemed to be like clock work. Cruising at 90 I punched it again, everything still working good. Close to the mixmaster I ran into traffic, cruising at 20 mph till traffic eased up,i tried to accelerate and the car bucked and lugged then felt like I was in nuetral. It gained speed but very slowly. I made the exit and came to a light. From a stop it didn't begin moving till close to 5000 rpm. The car wouldn't drive unless I put the gear selector into position 1. Got the car home into the garage and found I have no reverse. Sigh.
If the converter goes does the tranny go also?

it is VERY rare that a converter fails. There is really not many moving parts inside a converter and if it has worked before then it is definately not the converter

Do all the other gears work properly or is just reverse out? I don't think its a converter issue. Possible issues could be lo-reverse clutches are worn out, fluid leak in the reverse apply circuit, worn boost valve or broken sunshell.

When my TC went out, the car wouldn't move unless it was turning 4000rpms in any gear. It locked up at WOT and broke when shifting from 2nd to 3rd. I knew immediately because the rpms shot up when it was supposed to be shifting lol. Mine was a TCI 3500. Didn't destroy the transmission though. Went through it and everything was good. I couldn't see flakes on the dip stick but when I dropped the pan, the fluid looked like candle apple red paint (super fine flakes from the stripped clutch material).

had the clutch fail on my torque converter, the car would buck sitting in gear but not in park, but when given gas the car would drive like normal...plus alot of material was around the pump when we pulled it apart, took my chance and just cleaned the trans out, and with a new converter its been all good and that was around 6 months ago

So I'm off work now.... Pulled the dip stick, no flakes. Fired the car up and it backed up just fine. Drove down the block 1-2 shift just fine, half way through second it feels like it slipped into nuetral, wouldn't pull again until I manually down shift. Well time for a new tranny I'm thinking. Sigh. Guess I try my luck with performabuilt.

Yes I was saying that setup wont make enough power to hurt a Yank, they are a top notch piece.
Your latest post sounds almost like a 3-4 clutch failure.
Again though you still need to have both gone through, when one fails it contaminates the other. I would be looking at FLP or Rossler.
