has anyone had this problem?my 2001 supercrew with a 4.6 shakes for a couple of seconds when comimg to a slow stop in stop and go traffic ,it also feels like it may stall out,the tach does not move when this happens,its at the dealer right now,so far they cant find anything wrong.

 

Are you sure it's not warped rotors? Mine did the exact same thing you describe. It only did it during slow stops, I couldn't feel it during harder stops. I replaced the rotors and the problem was solved.

 

Probably the brakes. Does it shake if you coast to a stop or only when you use the brakes?

 

If the RPMs aren't jumping around or getting down low on the stop, then it might not be the engine. Of course when mine shook when I forgot to plug in a coil-pack... oops... the tach didn't move much and you wouldn't notice it easily.

 

okay heres an idea use the tranny to slow u down and u will know if its ur brakes or engine missfiring... if u doing about 50mph u can drop it into 2nd and idle speed will bring u down to about 20mph

 

i dont think it is the brake rotors because the shake continues for a few seconds after i stop,it is still at the dealer a second day,hopefully they will find something.

 

fuel filter? pump? plugs? Have you tried different brands of gas to see if that has any impact?

 

the dealer just called and said the problem is in the transmission,thanks for everyones help!

 

Glad they could find the cause! Sometimes they just send it back to ya and said they couldn't find anything wrong even though you know it's there.

 

Ah, didnt know that. In that case I agree its not the brakes.

edit: DOH! I REALLY need to start reading all of the thread LOL

 

clutch band is probably worn and slipping... thats just a intial guess...

 

as of today the truck is still in the shop,i will let you know what they replaced when i get it back,the truck only has 28.000 mile on it,has anyone else had tranny problems at this low mileage?

 

I kind of had the same with my 97 4.6 one dealer said it was the trans took it to another and replaced the fuel filter didn't do it any more under 30000 miles

 

the fuel filter was replaced at around 25000 miles.

 

i finally got my truck back after 2 weeks at the dealer,they replaced the valve body and the 2-3 accumulator piston,after driving it a few days i can now confirm that it is repaired!
