TQ is locking at very low speed?????

[tpabayflyer]

My 136K mile GN has been acting funny lately...... The trans will appear to lock up the converter from just leaving from a stop..... like it shifts into 2nd and the converter is locked... then it hits 3rd very quick and the rpm's are very,very low... like around 1,000rpm or just off idle. If I put my foot down, the TQ will unlock and downshift normally and all is well. Thios has happened 3 or 4 times in the last month and only after highway use.... is this a common type of failure??? tia TBF
