bought my truck at 52,000 and tuned it at 56,000. now im right at 69,000 and the tranny is done for.. got her parked hopefully waiting to get a river city diesel tranny! truck has s&b intake H&S 300 tune shift strategy 1L, also has delete pipe 3.55 gears on stock tires, Truck was freakishly strong with just a tune so im not shocked at all, still love the hell out of the truck!

Got mine with 89k tuned at 92k and it has 103k. Iv'e run the spartan 275 mostly, but have run the 310 and 300 some. I have had some puking issues, but everything else is great. Unbeleiveable power. A friend of mine helped me do the dpf delete and install the exhaust and as soon as we got done I loaded the 300 tune and busted his 07 lbz efi live tuned dmax! Although I would like studs and an egr delete to make me feel better about the reliability because I have a pretty heavy foot! :ford:

100k miles tuned since day 1. 345 tune for a year and a half. Had transmission apart in dec for inspection. All good. Reseated and reassembled. Put a new stock converter in it because i could. Reset adaptives And continued abusing it.

How do you guys know if your TC is slipping? I'm getting ready to put some mods on mine, but I've had some shaking occasionally when the truck is under pull, (i would compare it to like the engine is missing or a clutch is chattering), usually in 4th gear at about 50 mph and 2500 rpm. It only does it occasionally and I have to be pulling a big hill or have a trailer on, but even then it's only intermittant and sometimes it's worse than others. I can't seem to do it on purpose, I've tried many times, but for some reason conditions occasionally become right and it will do it when I'm not trying. I didn't know if this was my TC slipping or something else or how to tell, but I'm concerned if I crank up the hp, it's going to go completely.

Little under 100k been running the Spartan 275 since 2k. No issues, switched to Amsoil full synthetic at 50k.

450, tuned/deleted at 52,000, now at 113,000, AFE, Deleted, Spartan tuned. Was SCT on Xstreet, and H&S on 300 HD. Stock trans, and I mean stock, even the fluid.... Never changed since she rolled off the lot. Hasnt leaked but about 1 quart when my pan bolts were loose. Still less than 6 RPM slip when Daily Driving the 250 Spartan, early lock tune, and less then 10 RPM slip on the 210 Tow Performance tune, with 18 K 5th wheel behind her... Temps usually stay around 175 in town, 185 on the highway, and 200-210 towing heavy. When she blows, Ill go with the stage 3 from elite, and an RCD TC, but I think she has a good bit more in her still! LOL
