94 chevy luminaz z34. I need to change the trans fluid to change a the tcc solenoid. The fluid has been neglected since the trans replace. About 70000 miles. I hear I am going to ruin the trans most likely if I change the fluid. What should I do?

If that is the case it would mean that the damage is already done and the fresh fluid is just exposing it. Not changing the fluid might put off the inevitable but you would have to deal with it eventually any way. If the fluid is dark and smells foul, you;re looking at a transmission job anyway.

I would change it. You have a chance at still preventing a problem if the damage isn't done yet and if it triggers something, it was already there anyway.

I feel like I should also mention that other than the tcc locking up for no reason it shifts and runs great. Would it be a bad idea for drop the pan and not replace the filter and reuse the fluid? Maybe cut it with fresh fluid?
