High-Mileage Jimmy

[Shakespearesdad]

I bought My '88 Jimmy new and have now racked up 323,000 miles. I killed the original engine when it had 275,000 miles on it( Heavy boat, mountain road, stuck thermostat,nowhere to stop, BIG BOOM) I replaced it with a crate engine and have had no problems.
Anybody else have a high mileage truck? Any idea on tranny life? 700R4

from what ive heard 700's are good for about 125,000 miles before needing a rebuild...some go longer but that seems normal from my experiences and others

the last accurate reading on mine was around 400,000 miles and that was about 8 years ago the odometer was replaced i bought it with a blown motor and a ragged tranny it still doesnt run got the motor in no money for the little stuff
