first post...o/d light flashing,trans noise

[4.0exsport]

This is my first post here & I have a question.My wife went to church this morning( I had to stay home w/h a sick 12 yr old) & says the o/d light started flashing & truck is making a noise,so I drove it ...when it is in gear it makes a rattling sound some what like a converter shield come loose but not in park or neutral,truck shifts perfect,& after I drove it about a mile the light went off but it was on the whole way home from church a distance off about 25 miles she tells me.I did a search & I didn't like what I read!Anybody got any good news for me? Tomorrow I'm going to go under it to see if a mount or shield is broke but was just trying to get some ideas of what to look for.btw I checked the fluid & it's not burnt or low.

p.s. it's a '97 explorer sport with 4.0sohc engine,4wd w/h about 90,000 miles & I changed the trans filter for routine maintenance about a month & 1/2 ago & there were no signs of metal or damage Scott

Change your TPS. It's about 20-30 bucks. That's likely your tranny problem. The rattling probably is your cat heat sheild.

Was it flashing all the way home or solid? If solid, she may have accidently hit the OD off button. As long as it is shifting ok, you should be alright. May want to have your alternator checked, cause if that starts to go, it can cause shifting anomolies. If the light comes back, you can try disconnecting the battery to reset the computer. If it was a one time glitch reading, then that may take care of it.
