Overview:
Ford Mustang, Ford Explorer, Ford Ranger, Mercury Mountaineer, Transmission shifting perfect then all of a sudden one day it won't go forward or reverse? You read all the forums and all they say is the transmission needs to be rebuilt and all for the shops want $1800 - $2400 to rebuild it. Or are you looking for a side hustle and you keep seeing mustangs, explorers and rangers on marketplace and craigslist with bad transmission no forward or reverse, this could either save you a lot of money or make you a lot of money depending on your situation, but I really hope this video helps you out..
I ran into a very common problem associated with the S197 mustangs..
It started out one day getting on the highway when we floored it to get over, instead of just going like usual, the motor revved high like the car was in neutral and we didn't accelerate at all, after a few seconds it finally caught and I made it to work. The car ran fine for a few months, the same exact thing happened again but this time to my wife. The car ran fine for about another week and it happened one last time, this time when she made it home, the car would no longer accelerate forward or in reverse and we knew we were in for a rebuild. The cheapest local shop wanted $1800 for a turn key operation. After trial and error and a lot of research, I have narrowed down this very common problem to a $25 part, The Over Drive Sprag. The Over Drive Sprag is a one way bearing that acts as a clutch and when it fails it doesn't lock up when it is suppose to, which allows the gears to spin inside of the transmission instead of sending power to the wheels. If you replace this part at the early warning sign I have given you above then you reduce the risk of damaging any other parts, or breaking down and being stranded due to it's failure.
In total I spent around $500,
If your fluid is clean when you check it you may not need to replace torque converter, fluid or filter, you may re-use them, but it is recommended to replace all of these things as preventative maintenance while going thru this process, but if you were to only replace the sprag itself you should be able to drive again for around $25..
