7.3 auto trans?

[whtcoupe]

So what's the deal with these things? I see some people have theirs go out before 100k and some go well past 200k with no trouble! I'm purchasing a 2wd 2000 f250 w/ 7.3 and auto trans this week. It has 75k miles and it is mint. Would it be wise to eventually upgrade the aux trans cooler?

Cheers, Brian.

I put in a new one at 87k one at 165k and one at 260k and this one slips sometime,truck now has 285k.

Best mod is to get a 31 row 6.0 trans cooler quick.

thats probably your problem, any bit extra of performance without trans tuning of any kind will just tear them up...iirc
