The A4LD transmission is the most common failure on early explorers. It's very likely that your transmission is failing.
clutch plates could be welded to gather
Reverse is usually the first to go, followed by first gear. Time for a transmission rebuild.
it needs a new transmission
if an automatic transmission is grinding in reverse it is probably an internal failure. The car will probably need a good mechanic who specializes in transmissions to look at it to be sure. I have seen some cars with a simple linkage problem do this...but its unlikely.
Depends on the transmission. Many transmission bands are not adjustable.
Check your Automatic Transmission fluid level
On the Ford Explorer , on the end of the automatic transmission gear selector lever ( park , reverse etc ) there is a push button that allows you to turn off the OVERDRIVE feature if you wish
Put it into reverse when moving rapidly forward.
Everything points to the transmission being rebuilt or replaced. The reverse band broke, came loose etc.
1998 ford explorer transmission reverse won't engage, acts like it is in neutral.
The A4LD transmission is the weakest part of the 91-94 explorer. It is likely that your transmission has failed.
My 2001 hyundai accent has no reverse
