Take it back to the dealership! Sounds like wrong fluid was used or damage was caused by fill procedure. Gm transmissions are also electronic and components such as solenoids could be failing. Never Never change or flush GM transmissions as early as 70,000 miles if it is normal use. You are asking for trouble. Under normal use they are sealed and can go for 100,000 mile under normal operation

75,000 miles isnt alot of miles,unless they were mostly city miles. If you aren't experiencing any transmission problems,i would drop the pan,change the filter and whatever fluid the pan holds,and hold off on flushing the entire sytem.The clutches and bands sometimes don't do well when shocked with ALL new fluid that contains a certain amount of detergent.The only real problems i have seen with the total flush is on Dodge trucks of the 90's up to even 2000 and some later models,the transmissions use a governor pressure sensor,and solenoid,and i have seen many of them set codes after the flush,and the components having to be replaced with new.Black fluid isn't a good indicator.Brown fluid,is better than black.And red fluid is the best.

Regardless of what dealer tells you, there is no such thing as lifetime fluid. Even the best fluids such as synthetics should be changed. Change intervals should be regarded as false as well...If you changed all the fluids once a week your vehicle would last far longer than it does...Obviously this would take up a lot of time and $, but reasonably engine oil should be changed at at least 4,000miles, trans fluid every 25-30K. Otherwise the oil begins to chemically change loosing it's ability to do it's job and also carries fine contaminants with it that begin to wear components.

It is best to flush the fluid this gets the fluid out of the torque converter.This transmission uses special fluid tpye t-Iv gm # 88900925 do not use dexron fluid in this transmission.
