converter issues
 

i have noticed that my TQ converter is locking and unlocking when going down the hi-way, it's a triple disk suncoast converter, is this normal or do i need a lock up switch, i am having a valve body put in this week so just wondering if i need to do some thing else.
thanks in advance:tu:

no your having some isssues there its called the fourth gear hunt. its ususally static noise in the electrical system from the apps to the transmission. you can fix it with a bypass resistor or a line cut out. you can find the info for it on ats website if im not mistaken. or the lockup solonoid could be going out causing it as well
