I just change the tranny becuase after driving an 1hr & Half the shift are hard ,after changing it ,it dose the same. i change the mount on it . it doesn't shift as hard but it dose the same what can it be

To much trans oil or wrong oil

are the bolts connecting the transmission to the engine tight? Check the engine mounts as well. if the engine is sliding around on broken mounts and cause trouble with transmission...

What did they check on the tranny to say that it's fine? Did that come with removing it and doing a rebuild? Or changing the fluids? Good luck! Nice thing, lots of f150's around from that time period still in scrap locations. Probably can get parts fairly cheaply, rebuilt or aftermarket...

I don't know why he's saying the instrument cluster...

looks like some good info here

Did it do it under hard acceleration? or just a normal take off. I have heard of engine mounts or tranny mount bushings getting old (not mileage old but just aging) causing a thump or clunking sound in between shifting. What happens is the tranny actually hits the undercarriage of the vehicle during high torque situations such as shifting gears. I have also seen the mount retaining nut back off of the mounts and the only thing holding everything in place is gravity. Another possibility is drive shaft u-joint problems, but if it were it would probably be making the noise more often. I dont think there is actually anything wrong with the transmission itself as usually when they go bad they dont magically get better. Hope this helps. Good luck!

sounds like your torque converter going bad. change the tranny fluid, and look for metal shavings (have a pro do this), sometimes you can squeeze enough life out of a bad tranny/torque converter by changing the fluid, or it might just be a clogged tranny filter. change the fluid, and if theres metal shavings in it, sell it while it still runs.

THIS A COMMON PROBLEM WITH OLD FLUID IN THE TRANS IT WILL DO THIS IS ONE THING ALSO IT KEEPS SHIFING IN AN OUT OF OVER DRIVE AT 55 MPH TAKE IT TO THE OIL CHANGE SHOP HAVE THEM CHANGE THE TRANNY FLUID AND THAT TOOK CARE OF IT SHIFTING IN AN OUT OF OD .. TRANNY FLUID SHOULD BE CHANGED EVERY 80K MILES BUT NO ONE EVER DOSE THIS IT IS 10 WEIGHT OIL AND IF IT LOSES ITS VISCOSITY IT WILL NOT FLOW RIGHT THRU TRANNY AND OVER DRIVE IS HARD TO GET IT IS A LOCK UP COVERTER ON THIS BLAZER FOR OVER DRIVE .. SO CHANGE THE FLUID AND ADD LUCAS TRANNY FLUID CONDITIONER THIS WORKS ABOUT 60 % TO 70% OF THE TIME I HOPE THIS WORKS FOR YOU OH BY THE WAY DON'T LET THEM TALK YOU INTO A FILTER CHANGE JUST MORE EXSPENSE RIGHT NOW IF THIS WORKS YOU WIL HAVE OVER DRIVE WHEN YOU LEAVE THE OIL CHANGE SHOP LOL POHLCAT

throw out bearing

First change tranny fluid and filter. Check the tranny mounts and motor mounts. The GM's also have an automatic torque converter clutch circuit that can cause problems just like this.

Ford Explorers are nice, but are commonly known for the trannsmssion to fail, I know becuase I know of people who also went through this tranny problem, Get it fixed and install a new tranny cool, heat is the number one cause for failure. I personally wouldn't get a Explorer from other peoples experiences.

try some transmedic .put a little in tranny .try to take out some fluid add it in dont over fill transmission .put about a half of bottle in it. it wiil loosen those stuck shift valves.

You need to bring it in for a transmission inspection/overhaul. The bands are not catching, and the fliud is turning black because it its burning up and iverheating.
