How to adjust tq converter unlock? Now I have a 4l80e in both my trucks, with similar setups. Both of them unlock the converter the instant you lift the throttle, no matter how brief the lift. I don't recall the 4l60e's doing this, at least not as bad. I want to keep the converter locked, what tables do I change with Edit to do this?
In case I didn't explain what I am trying to accomplish good enough.....here is an example-driving along at lets say 70mph and lift (or tap brake to kill cruise) the converter unlocks instantly (tcc duty cycle goes to 0) coast down to 69 mph and then as soon as I lay my foot back on the gas the rpms come up a bunch (loose stall) then it starts commanding the tcc and as it relocks the rpms come back down. This is very annoying to me and I want to keep it locked for at least a few seconds of coasting.
