Hey guys ive got a 1999 F150 with 112,000 miles on it and i was wondering when the transmission usually goes out. thanks.

 

With regular maintenance and minimal hard use, one can last over 200,000 miles. A friend of mine has a chevy with close to 300,000 miles on the original engine and tranny.

 

I have 113000 miles and i cant even tell you how hard mine has been ran, plus towing a lot of heavy loads over 5000lbs for 300+ miles... still strong, just a shift kit.

 

My 97 5.4L has 218,000 miles on the original engine and transmission. It runs fine, and if I drove it more, would probably make 300K without changing or rebuilding either.....

 

90% of the time when they overheat. You can prevent that with fresh fluid, an extra cooler, or a temperature gauge.

150,000 and mine's finally fried.i've pulled the bobcat,tractors,trucks and anything else i could hook too.i just took it through a pond(more of a lake really) and had water over my hood like 2 weeks before it went out.i was slammin it into drive and reverse not lettin it drop down to idle so it wouldn't flood.i was really drunk that night and my budd started talkin ***** sayin i couldn't make it through.she made it and i also had to put a new starter in it then the tranny finally died.my truck has been through 150,000 miles of pure HELL though.i just put the shift kit in it a couple months ago after it started slippin in august.if you get any fine metal shavings in your fluid i would advise against changin it unless you park it right then and rebuild it.otherwise,just keep drivin it cause mine was fine til i changed the fluid after i noticed some sludge on the dipstick(metal) then it started slippin and finally fried.

 

alright thanks for the info. how much does a new tranny usually cost?
