How long does a 700R4 last?
At the very least, a rebuilt unit should last this long. However, if a rebuilt unit is paid more attention and care in terms of small, regular maintenance jobs, this ‘like new’ unit could conceivably last as long as any new unit – around 150,000 to 200,000 miles on average.
What is the difference between a 700R4 and 4l60?
You can’t tell the difference between a 700R4 and a 4L60E by the oil pan as they are nearly the same. If the transmission has a large 18-pin electronic connector above the passenger side pan rail, it’s a 4L60E, as seen here. If it has a cable connection near the cooler lines on the passenger’s side, that’s a 700R4.
Will a 454 bolt up to a 700R4?
Yeah a stock 454 won’t kill a stock 700r4 unless you’re planning on towing with it or hot rodding the 454 some day. Once you upgrade something though you’ll have a hard time with the weak parts like planetary, power band, output shaft. All of those should be upgraded if towing or building the engine are in your future.
