Perhaps when the engine and the transmition were "conected" something did not align properly. Did it work when you first did it or it never worked.
On a 1995 Ford Explorer : Looking into the engine compartment from the DRIVERS SIDE ( a flashlight would be helpfull ) the starter is LOW DOWN at the rear of the engine where the automatic transmission is bolted to the rear of the engine
Fuel pump, I think I have heard of this problem before
A 1999 Ford Explorer Eddie Bauer has the 5R55E automatic transmission with the 4.0 liter SOHC , V6 engine , and the 4R70W automatic transmission with the 5.0 liter V8 engine
it is almost 100% your transmition selenoid. the same thing happened to my yota, and the 1997 auto trannys are notorious for that. if you use one of those engine code readers it will probably say "transmition selenoid#2".
Starting with the 2002 Ford Explorer 4 door there is no automatic transmission dipstick
According to the 1996 Ford Explorer owners manual : Motorcraft MERCON automatic transmission fluid is used in the automatic and manual transmissions with the V6 engine
4R55E - 4 speed automatic - with the 4.0 L - OHV - V6 engine 4R70W - 4 speed automatic - with the 5.0 L - V8 engine
According to the 2001 Ford Explorer Owner Guide : The automatic transmissions are : For the 4.0 liter SOHC , V6 engine ( 5R55E ) For the 5.0 liter V8 engine ( 4R70W )
My ( 1995 ) Ford Explorer XLT , 4x4 , automatic , 4.0 liter V6 engine had a shipping weight of 4,053 pounds
My 1995 Ford Explorer XLT , with 4.0 L OHV engine , automatic transmission and 4X4 had a shipping weight of 4,053 lbs
Starting in 2002 the Ford Explorer ( 4 door ) does not have an automatic transmission fluid level dipstick
The automatic transmission fluid dipstick is on the passenger side of the engine by the firewall
