I have posted about this a couple times.. and i still just can't figure it out.. this past weekend i flushed out my tranny system again.. replaced fluid, filter, and gasket. like suggested before.. i am still getting a klunk on the downshift from 3rd to 2nd gear, always right at 20 mph.. i have even taken it into the shop.. they cleaned my throttle body and sent me on my way.. i have replaced the TPS just incase..
I am still getting the same thing.. it happens more if i am breaking.. then if i am coasting to slow down, and it happens more in warm weather than in the cold. .. i think its a curse..

 

What year Explorer? U-joints, motor mounts, and transmission mounts all solid?

 

this is for my 98 xlt. i can check those mounts..
