Thanks for the info.. Here is an update.. I took my son to his baseball game, another rainout, so I stopped by Advance Autoparts in town to see if they had a torque converter and would the cost is.. He first could not believe it went bad with only 157K on it and asked about the fluid also.. I told him I have never had the fluid flushed so I figure it is bad.. He said he would just have the system flushed and serviced and see if the noise goes away.. He said he has done that in the past and it cleared up the problem.. He said if I pull the stick and it is dry, I have a big problem... So I got home and checked the fluid and it was a little low and brown in color.. Should I take it somewhere to have the system flushed and see if the problem goes away?? He said that would cost less than $100 and might solve the problem because he has never heard of a torque converter going out on a Toyota with those kind of miles.. I said my wife drives it to school (teacher) about 20 miles roundtrip and never been off road.. Any suggestions?
