Ok i got my truck altogether tonight and took it on a test run. It seemed the tc never wanted to unlock at 70 mph (2500 or so rpms) it was on cruise up hill down hill straights never unlucked. Also when i stepped on it at 70 it shifted down to sencond for a sec hit rev limiter then 3rd back to second the went and took off. I got a nelson tune but is my compter still learning everything?? Any help would be great. Thanks

 

sounds like your shift tables are off. not sure what mods you have done. but i'm in the same boat in hitting the rev limiter in second. gonna have Allen redo the tune to fix it.
mine also started doing this after the stall install

 

Ya i thought it was all jacked up. I am still not sure what is up. I installed a transgo to and servo. Everything looks fine in there. I have no washers in it either. It is just bothering me. Hey Parrish8 maybe can help me out i will be in his neck of the woods Sunday. Any more info will be great full. All my mods are in sig.

 

If you're on cruise, the TC will not unlock...no need to. The only way it will unlock is by pressing the gas whatever amount necessary that is in the tune..i.e. if the tune has the TC unlocking when the gas is pressed X% at X mph, then it will...

And either your shift points are wrong or your rev limiter is.
