Could dirty transmission fluid cause shift solenoid problems?

Eagle. How can you posably do any more damage?

dandyoun. Thank you for a useful response. Would you suggest attempting to clean the solenoids at all of they appear to be covered with dirt/trans fluid mix? The outside of the pan is covered with this so my assumption is the solenoids may be as well.

Truth is it probably needs to be gone completely thru. But if you like me at times that may not be financially possible. Carefully cleaning anything you can get to with pan off may be ok. Just use caution cause anything you move will break other debris loose. Make sure to get out what you can without flushing. I not a fan of flushing one in this condition cause you break this stuff loose and it gets in more critical areas your problems get worse. The CTC works wonders at times. Swells all rubber seals and cleans as it circulates. Put some in after you change the fluid and filter. And good luck cause it's a crap shoot whether or not all this will do you any good with it in such bad shape. But I would try if it was mine just to get me by for a while.

I've found a trans for $300, but I got the vehicle for free. So I'm trying to to make do with little $ spent. Much appreciated dandyoun. I'm more keen to the idea of a simple fluid/ filter change. Thanks again.

Ok. The CTC can be found at car quest stores and it does wonders on shifting problems with auto trans. Might want to add some with the new fluid.

Not an answer a question my 96 blazer won't get go past 30 in drive it is an auto tran what and the transmission fluid is clean what could the problem be
