Trans life expectation after lift

[Bradley3054]

Hey everyone i had bought a 8 super lift with 37 for my E99 7.3 and i was wondering how long you all think my trans will last. I have a e99 7.3 with auto and 3.73 open rear 4x4. I do 90% highway traveling at 60mph, i dont drive fast much and i dont race around, btw i also have tw 6 pos chip and 164,000 stock trans. Also when this trans does blow i plan to get high performance trans and that should hold up alot better correct? Give me your input guys thanks. P.s just bought 6.0 trans cooler.

When time/money permits, change your gears to 4.30 if you dont tow or tow very much........... or change them to 4.56 if you do tow heavy stuff. Your trans will thank you........... and last alot longer. Get a trans cooler from a 6.0 truck as well. All should be good

My bad, I didnt see you already have the cooler. Good luck

Hey i am about to install a 6" lift on my 02 F250 7.3L and this thread brings me to ask the question - Should i change my gears? I dont really do any towing or hauling, mainly highway and in town driving. Also, how can i tell what gears i have now? and depending on what i have now, What should i have with a 6" lift and 35" tires??

thanks

If you're not towing heavy, then 35s will be fine with stock gears. It's what I'm running. But, with a 6" lift, I think you will want bigger tires.
