Hi, My name is ***** ***** for the delay.
I will do my best to assist you
i would think your assumption is correct..
the problem seems to be the 2-4 band,,it is worn out or the servo seals have blown,
a common thing is the servo bore will wear on this transmission and will need to be re-sleeved.
sorry,but i do not see an easy fix for this one,the transmission will need to be rebuilt or replaced
