I'm not tryin to diss you in any way, but thats what a trans flush is supposed to be. If they are using chemicals other than just the trans fluid recommended for ur car, they are at fault if anything breaks down. So iif and when you go to do this, make them state on paper what they are going to be using for the flush.ctruss said:If you feel a flush is needed, make sure no cleaners or chemicals are used. You can do a flush by simply running trans fluid through the trans.
