Question about 2002 Ford F150 Regular Cab
When truck down shifts going up hill the trans makes a loud clunk
If this is a 4X4 then the problem is most likely the slip yoke not sliding smoothly on the transfer case output shaft splines. You can correct this bt lubricating the slip yoke splines with Teflon Grease .
If it is a 4X2 then lube the output shaft splines on the back of trans.
