Should I worry about the transmission in my 2008 f250 (diesel) after driving it with a superchip for a year ?

Im curious if my tranny should be gone by now, i got the truck the day i turned 16 with 6" lift 37" tires and a superchips flashpaq on performance the entire time, ive already gone through a set of Nitto mudgrapplers and now have toyo M/Ts this was the truck i worked all summer in cutting hay and constantly driving, truck had 12,000 miles when i got it in june of 2010 and now has 43,000 on itShould I worry about the transmission in my 2008 f250 (diesel) after driving it with a superchip for a year ?
why should it be gone? ford builds some hardcore trucks, you should be getting another 100,000 miles out of it, change the oil in the motor and change the transmission fluid , service the transfer case and the front and rear end at 100,000, and the truck will likely last another 100,000. That truck was built to run , haul heavy loads, drag crap through mud ,dirt snow, and anything else you can think of. Keep up the maintenance and hang on to it.Should I worry about the transmission in my 2008 f250 (diesel) after driving it with a superchip for a year ?
Yeah you should worry, particularly if you didn't bother to regear the truck after the lift and 37 inch tires. If you have the stock gears, then the transmission has far less mechanical advantage that it was originally designed to have. So consequently more stress is put on it. Also if you're running a performance tune all the time that will put more stress on the transmission as well since the tune allows the engine to produce more power than the engineers planned on having in the truck, particularly with a diesel were a just a simple ECU tune can net over 75 HP and over 100 lb/ft of torque. It's easy to exceed the transmission's rated torque capacity.



What does your EGT look like when you're running the performance tune 24/7? That can give you a good idea on what kind of stress you're putting the drivetrain through.Should I worry about the transmission in my 2008 f250 (diesel) after driving it with a superchip for a year ?
it should be fine, my buddies 1999 f250 has 300,000+ on the stock motor he has changed the trans a few times because he hauls 20,000 pound trailers everyday but the original trans lasted to 200,000 miles when the engine had new high performance fuel injectors bigger turbo and a lot of other stuff i cant think of, it also has a shift kit in the trans even in the original so you should be fine and im sure newer f250's trans are built to last
